INDIA AND SOUTHEAST ASIA | REGIONAL RESEARCH MONOGRAPH

Preface: scope, definitions and method

This report examines India and Southeast Asia as interconnected but distinct political-geographic regions. India is treated as a single federal republic with extraordinary internal diversity and a continental-maritime position. Southeast Asia is treated as the mainland and maritime region comprising Brunei Darussalam, Cambodia, Indonesia, the Lao People’s Democratic Republic, Malaysia, Myanmar, the Philippines, Singapore, Thailand, Timor-Leste and Viet Nam. Timor-Leste became ASEAN’s eleventh member on 26 October 2025; the report therefore uses the 11-member composition current as of 25 October 2026. ASEAN membership is an institutional fact, not a claim that every state has the same political system or foreign-policy preferences. [1,2]

The report distinguishes history from contemporary analysis. Ancient and precolonial chapters cover migration, trade, religion, states, empires and maritime worlds; the modern chapters examine colonialism, independence, the Cold War, ASEAN, India’s post-1991 economic and diplomatic changes, supply-chain realignment and current strategic competition. Contemporary facts are time-stamped to 25 October 2026. Economic numbers are identified by source and forecast vintage; forecast values are not treated as realized outcomes. ADB’s September 2026 outlook projects developing Southeast Asia’s growth at 4.7% in 2026 and

4.9% in 2027, while India’s FY2026 growth projection is a separate fiscal-year measure. [3,4] The source base mixes official data and policy documents with academic books, peer-reviewed research, international organizations, regional think tanks, and dated reporting from reputable news organizations. Official sources establish policies and institutional positions; they do not necessarily resolve disputed claims. Journalism gives current chronology but may not supply long-run causal explanation. Academic interpretations vary, and the report identifies uncertainty where necessary. A bibliography at the end provides direct links to the principal sources. The core analytical premise is that geography and history shape possibilities, but do not mechanically determine outcomes. The Himalaya, Bay of Bengal, Mekong basin, Strait of Malacca, South China Sea, archipelagic passages, monsoons and resource geography matter because states, firms and societies organize around them. Yet institutions, leadership, law, social coalitions, infrastructure and historical contingency determine how these constraints become political realities.

Executive summary

India and Southeast Asia form a strategically connected zone between the Indian Ocean and western Pacific. Their relationship is not a modern invention: trade, migration, religious exchange and the circulation of technologies linked the subcontinent to Southeast Asian ports and courts long before European colonialism. Contemporary interdependence, however, is being reshaped by the rise of China, strategic competition involving the United States and its partners, maritime disputes, supply-chain changes, climate stress, digital integration and political instability in parts of the region.

India brings scale, a large internal market, a major services sector, growing manufacturing ambitions, an Indian Ocean position, military capacity and a long tradition of strategic autonomy. It also faces structural challenges: job creation, uneven human development, informal employment, energy import dependence, infrastructure gaps, social inequalities, and difficult security relationships with China and Pakistan. ADB’s September 2026 outlook projects Indian real growth at 7.0% for FY2026, while the World Bank’s April 2026 update projected 6.6% for FY2027 under assumptions about higher energy prices and external disruption. These are forecast vintages and periods differ; the appropriate inference is resilience with substantial exposure to energy and trade shocks, not a single precise current growth number. [3,5,6]

Southeast Asia is not a single strategic actor. Indonesia emphasizes autonomy and maritime sovereignty; Singapore is a globally connected financial and logistics hub; Viet Nam seeks to preserve strategic room while managing its relationship with China; the Philippines is more openly strengthening defence ties with the United States amid South China Sea tensions; Malaysia and Thailand generally favour flexible diplomacy; Cambodia and Laos have close economic and political ties with China; Brunei’s diplomacy is shaped partly by energy and maritime interests; Myanmar is consumed by civil conflict; and Timor-Leste is consolidating its institutions as the newest ASEAN member. ASEAN’s consensus-based style enables dialogue but limits decisive collective action when member-state preferences diverge. [1,2,7-10]

A key current development is ASEAN’s digital integration. Senior economic officials resolved the outstanding issues in negotiations on the ASEAN Digital Economy Framework Agreement (DEFA) in May 2026, with the ASEAN Secretariat announcing the conclusion of negotiations on 1 June. ASEAN’s analysis suggests that a successfully implemented framework could help unlock a digital economy of up to US$2 trillion by 2030; this is a potential scenario, not a guaranteed forecast. The agreement’s significance lies in interoperability, digital trade, payments, data governance, cybersecurity and the ability to keep regional commerce open as global trade becomes more contested. [11]

Several contemporary risks are unusually acute. Myanmar’s armed conflict and humanitarian crisis remain severe: the UN’s 2026 plan said 16.2 million people would need assistance and more than 3.5 million had been displaced, while a July 2026 update estimated nearly 3.8 million people displaced. In the South China Sea, China and several Southeast Asian claimants continue to contest sovereignty, maritime entitlements and access; the 2016 arbitral award in the Philippines-China case clarified aspects of UNCLOS and historic-rights claims but did not decide sovereignty over land features, and China rejects the award. In October 2026, Philippines-China diplomatic tensions again escalated over remarks viewed in Manila as threatening. A separate Thailand-Cambodia land and maritime dispute followed deadly clashes and remained unresolved as of 23 October 2026.

The region’s economic trajectory is promising but exposed. Developing Southeast Asia is projected by ADB to grow 4.7% in 2026 and 4.9% in 2027, with substantial variation: Viet Nam remains among the stronger performers, Thailand’s growth is weaker, and Myanmar and Cambodia face country-specific risks. South Asia is projected at 6.4% in 2026, anchored by India, but fuel prices, weather shocks, and export restrictions can alter outcomes. These forecasts show how regional integration coexists with divergent domestic models, debt constraints, export dependence, and uneven development. [3,4]

The legal and social picture is equally heterogeneous. India has a written Constitution, federal parliamentary government, fundamental rights and an independent judiciary in formal design, alongside contentious debates about secularism, citizenship, religious freedom, federalism, media freedom, caste discrimination and due process. Southeast Asia includes electoral democracies, hybrid regimes, constitutional monarchies, one-party states and Myanmar’s military-dominated conflict environment. Legal traditions combine civil law, common law, customary law, religious personal law, socialist legality and constitutional models. ASEAN’s principles of sovereignty and non-interference can reassure states against intervention but also constrain collective action on human-rights emergencies. [16-20]

The report’s main conclusion is that India and Southeast Asia should be understood as a connected strategic system without assuming they will converge into a single bloc. Geography creates a shared maritime and ecological space; history creates links and memories; trade produces incentives for integration; and politics, law and national identity produce friction. The central question for the next decade is whether regional states can convert interdependence into durable public goods-secure sea lanes, resilient supply chains, digital trust, disaster cooperation, rights-respecting governance and infrastructure-without surrendering the political autonomy that many regard as essential.

PART I-GEOGRAPHY AND LONG HISTORIES 1. Scope, regional labels and analytical method

India is part of South Asia in conventional regional classifications; Southeast Asia is the region extending from Myanmar and mainland Indochina through the Malay Peninsula and the maritime archipelago to the Philippines and Timor-Leste. This report centres on India and Southeast Asia, while bringing in Bangladesh, Nepal, Bhutan, Sri Lanka and Maldives where they materially affect India’s neighbourhood and connectivity. China, Japan, Australia, the United States, Russia and the Gulf states appear as external actors because their policies affect the region; they are not treated as members of Southeast Asia.

A region is a useful analytical scale, not a natural political unit. ASEAN is an organization with a charter, summitry and institutional routines; India is not an ASEAN member. India participates in ASEAN-led forums and maintains a Comprehensive Strategic Partnership with ASEAN, but strategic interests differ among individual Southeast Asian states. ASEAN centrality is a policy principle and a diplomatic aspiration, not a guarantee that the grouping can always act cohesively. The ASEAN Outlook on the Indo-Pacific explicitly frames the Indian and Pacific Oceans as interconnected and calls for dialogue, openness, inclusion, rules and ASEAN-led mechanisms. [26]

The report uses four levels of analysis. First, geography identifies routes, barriers and ecological systems. Second, history traces how trade, religion, colonial power and war shaped institutions. Third, domestic political economy examines production, inequality, labour, public finance and development. Fourth, geopolitics analyses strategic competition, international law, alliances and state choices. These levels interact: a port is simultaneously a geographic site, a historical node, a development project and a military asset.

1.1 What the report does not assume

• It does not treat Southeast Asia as culturally uniform or assume that shared Asian heritage erases national difference.
• It does not treat ancient cultural influence from India as a one-way civilizing mission; local societies selected and transformed ideas, scripts, religious forms and political symbols.
• It does not equate all ASEAN members with liberal democracies or assume that ASEAN’s consensual diplomacy makes it a military alliance.
• It does not treat economic growth forecasts as realized GDP outcomes or combine fiscal-year and calendar-year numbers without noting the difference.
• It does not assume that international law mechanically resolves a dispute when parties disagree about sovereignty, enforcement and interpretation.

2. Physical geography and strategic space

2.1 India’s continental and maritime position

India occupies most of the Indian subcontinent and faces the Arabian Sea to the west and Bay of Bengal to the east, with the Indian Ocean linking both coasts to the Middle East, Africa, Southeast Asia and the wider Pacific. The Himalaya and Hindu Kush systems shape northern land routes, water flows and defence; the Indo-Gangetic plain concentrates population and agriculture; the Deccan plateau, Western and Eastern Ghats, arid northwest, northeastern hills and long coastlines create highly varied ecological and economic zones. India’s Andaman and Nicobar Islands sit near the approaches to the Malacca Strait, giving India a geographic presence near one of the world’s busiest maritime chokepoints.

The country’s geography produces both connection and vulnerability. Monsoons support agriculture but can also produce floods and drought. Major rivers cross political boundaries or originate in mountain systems shared with neighbouring states. Cyclones affect the Bay of Bengal and Arabian Sea. Long coastlines support ports, fishing, shipbuilding, tourism and energy infrastructure, but create exposure to storm surges, sea-level rise and maritime security threats. Regional strategy therefore depends on both naval capabilities and domestic infrastructure, coastal governance and disaster response.

2.2 Mainland and maritime Southeast Asia

Southeast Asia combines a mainland river-and-mountain zone with a maritime archipelago. The Irrawaddy, Salween, Chao Phraya, Mekong and Red River systems support rice agriculture, transport, settlement and states. The Mekong basin links upland catchments to Cambodia’s Tonle Sap, the Vietnamese delta and the South China Sea. Mountain chains and forested uplands have historically limited central control and sustained ethnic diversity. The mainland also connects to southern China, the Indian subcontinent and continental trade routes.

Maritime Southeast Asia includes Sumatra, Java, Borneo, Sulawesi, the Moluccas, the Philippines, the Malay Peninsula and many smaller islands. Volcanic soils, fisheries, forests, oil and gas, minerals, plantations and rich marine ecosystems have sustained diverse economies. Island geography creates logistical and governance challenges, while sea lanes support both historic commerce and modern container trade. Indonesia’s scale, the Philippines’ archipelagic reach, Malaysia’s position around the

Malacca approaches, and Singapore’s port and finance networks make the maritime dimension a strategic centre of gravity.

2.3 Chokepoints and maritime routes

INDIA Bay of Bengal Mainland SEA South China Sea

Malacca Strait Maritime SEA Pacific

Relational schematic only: not to scale, not a political map and not a maritime-boundary depiction.

The Strait of Malacca and Singapore channel connects the Indian Ocean to the South China Sea and onward to East Asian ports. The Sunda and Lombok Straits offer alternative routes through Indonesia; the Makassar Strait connects western and eastern Indonesian waters. The Andaman Sea and Bay of Bengal connect India, Myanmar, Thailand, Malaysia and the wider Indian Ocean. These straits are not only commercial corridors but also ecological regions, fisheries, migration routes and potential sites of naval competition. No one state controls the entire network; cooperation on safety, piracy, rescue, pollution and maritime law is therefore essential.

2.4 Rivers, monsoons and climate exposure

Seasonal monsoons underpin agriculture and water availability from India to mainland Southeast Asia. Their variability can generate simultaneous pressures on food prices, hydropower, reservoir management and labour migration. The Ganges-Brahmaputra-Meghna delta, Mekong delta, Irrawaddy delta and many island coastlines face a mix of flooding, erosion, saline intrusion, subsidence and cyclone risk. In upland areas, glacial and snow-fed rivers create changing risks; in tropical peatlands, drainage and burning can turn land-use decisions into transboundary haze. Climate risk is therefore shared but not identical: adaptation has to be basin-specific and sensitive to class, livelihood and governance capacity.

2.5 Geography as political opportunity, not destiny

A chokepoint is valuable only if ships use it, infrastructure is maintained, law and insurance allow predictable passage, and states can manage security risks. Likewise, river basins can promote trade or become arenas of conflict depending on dam operation, water sharing, agricultural policy and institutional trust. Geographic location gives India and Southeast Asia strategic weight, but ports, roads, railways, digital cables, customs processes and political agreements determine whether that location becomes prosperity or vulnerability.

3. Ancient and precolonial connections across the Bay of Bengal

3.1 Maritime commerce before European arrival

For many centuries, maritime and overland networks connected eastern India, Sri Lanka, the Bay of Bengal, the Malay Peninsula, Sumatra, Java, Borneo, mainland Southeast Asia and South China. Traders moved textiles, beads, metals, ceramics, spices, forest products and prestige goods; sailors used seasonal monsoon patterns; ports served as entrepots where regional merchants exchanged products and information. These networks were built by Indian, Southeast Asian, Chinese, Arab, Persian and other traders, rather than by a single civilizational source.

The Bay of Bengal has often been described as a bridge rather than a barrier. Historian Sunil Amrith’s work on the Bay emphasizes circulations of labour, migration, capital, ideas and environmental change. The same waters carried merchants, Buddhist monks, Hindu teachers, Muslim traders, colonial soldiers, indentured labourers and modern migrant workers. The sea connected coastal societies while also leaving inland uplands and many island communities relatively autonomous.

3.2 Sanskrit, Pali and political adaptation

Sanskrit, Pali, Indian religious texts, royal titles, scripts and ideas of kingship moved through networks of trade, pilgrimage and elite emulation. They shaped states such as Funan, Chenla, Angkor, Champa, Srivijaya, Majapahit and several mainland polities, but the processes were selective. Local elites adopted and adapted forms that served local ritual, political or diplomatic needs; Southeast Asian languages, cosmologies, social institutions and art remained active sources of innovation. “Indianization” can be a shorthand for some transmissions, but it becomes misleading when it suggests passive recipients or direct Indian political control.

Buddhism moved along multiple routes: Theravada became influential in Sri Lanka and much of mainland Southeast Asia over long periods, while Mahayana and esoteric forms shaped other courts and networks. Hindu traditions influenced royal ritual and monumental art, particularly in Khmer and Cham contexts. These categories coexisted with local ancestor worship, spirit traditions and indigenous cosmologies. Religious change was never simply a replacement of one system by another; practices often accumulated, blended or changed by setting.

3.3 Maritime states and commercial power

Srivijaya, centred in Sumatra and its surrounding maritime world, is a classic example of a polity whose influence depended on control of routes, ports, diplomacy and ritual prestige. Later Javanese and Malay states, the Malacca Sultanate, Ayutthaya, Pagan, ■ai Viet, Khmer polities and many coastal sultanates developed different balances between agriculture, trade, tribute and military power. Their histories show that Southeast Asia was never an empty space awaiting European arrival. It contained dense political systems, sophisticated craft production, legal customs, religious institutions and extensive exchange.

3.4 Islam and the Indian Ocean world

Islam spread through trade, scholarly networks, rulers’ conversions, Sufi movements, marriage, migration and political change. Coastal Sumatra and the Malay world became major centres of Islamic commerce and learning; Muslim communities also grew in Java, the Philippines’ southern islands, mainland ports and India. The process was gradual, diverse and shaped by local rulers. Islam in Southeast Asia developed through local languages and traditions and remained distinct across the Indonesian archipelago, Malay Peninsula, Brunei, southern Thailand, southern Philippines and other settings.

3.5 Indian Ocean and Southeast Asian legal cultures

Precolonial legal orders combined ruler’s commands, court procedure, religious norms, customary law, village institutions, kinship, trade contracts and diplomatic arrangements. Buddhist monastic codes, Islamic jurisprudence, Hindu legal ideas, royal decrees and local adat systems could coexist. Modern legal systems inherited different parts of these traditions through colonial law and postcolonial reform. There was no single, continuous “Asian law” shared by India and Southeast Asia; legal borrowing occurred through local political choices and later colonial restructuring.

3.6 Trade and the limits of civilizational narratives

The historical connection is real, but it should not be converted into a claim that Southeast Asia was merely an extension of India or that contemporary diplomacy should be based on a single civilizational identity. Modern states choose their own histories and identities. Shared Buddhist, Hindu, Islamic and linguistic traditions provide cultural links, but they coexist with Chinese, indigenous, European, Austronesian and local influences. Historical depth is strategically useful when it expands understanding; it becomes unhelpful when used to erase sovereignty or pluralism.

4. Colonial conquest, national movements and the Cold War

4.1 Different colonial empires, different institutions

European expansion in the region was uneven. Britain ruled much of India and Burma and established influence in Malaya and Singapore; France built Indochina across present-day Viet Nam, Laos and Cambodia; the Netherlands consolidated control over the Dutch East Indies; Spain and later the United States shaped the Philippines; Portugal held Timor and other enclaves; and Siam/Thailand retained formal independence while ceding or adjusting territories and navigating great-power rivalry. Colonial rule varied between settler enclaves, plantation economies, extractive administrations, strategic ports, and indirect arrangements with local rulers.

Colonial governments reshaped property, land revenue, labour, education, census categories, religious administration, legal codes, transport and borders. These systems created new institutions and global connections while also extracting resources, constraining sovereignty, privileging certain groups and racializing access to law and work. Plantation slavery, indenture, forced labour, cash taxes and export agriculture affected different territories in distinct ways. The resulting economies were not equally developed and not all colonial borders had the same social impact.

4.2 Nationalism and independence

Anticolonial movements developed through a mixture of constitutional politics, religious revival, labour organizing, peasant protest, student mobilization, armed resistance and mass parties. India gained independence in 1947 amid Partition; Indonesia proclaimed independence in 1945 and secured sovereignty after revolution and negotiation in 1949; Viet Nam’s independence struggle involved war against France and later the United States; Burma/Myanmar became independent in 1948; the Philippines in 1946; Malaya in 1957 and Malaysia in 1963; Singapore in 1965; Brunei in 1984; Viet Nam, Laos and Cambodia experienced their own revolutionary and conflict pathways. Timor-Leste’s independence in 2002 followed Portuguese withdrawal, Indonesian occupation and a UN-supervised transition.

4.3 World War II and Japanese occupation

Japanese expansion during the Second World War broke the myth of European invulnerability and profoundly altered Southeast Asian politics. Occupation brought extreme violence, forced labour, resource extraction, famine and the mobilization of nationalist movements. It also changed military structures, administration, and the political opportunities available to independence leaders. The legacies varied by country; wartime collaboration, resistance and survival produced contested memories that continue to shape public history.

4.4 Cold War alignments and conflict

After independence, the region became a theatre of Cold War competition. India pursued non-alignment and strategic autonomy; ASEAN’s founding members sought stability and regime security; mainland Southeast Asia experienced wars and revolutions; Indonesia moved through shifting domestic and international alignments; and the United States, Soviet Union, China and regional states influenced conflicts in Indochina and beyond. The Vietnam War, Cambodian conflict, insurgencies in Burma/Myanmar, and confrontations around the South China Sea made security central to state formation.

4.5 ASEAN and regional order

ASEAN was founded in 1967 by Indonesia, Malaysia, the Philippines, Singapore and Thailand. Brunei joined in 1984, Viet Nam in 1995, Laos and Myanmar in 1997, Cambodia in 1999, and Timor-Leste in October 2025. ASEAN’s norms of consensus, non-interference, peaceful settlement and gradual integration reflect both regional aspirations and the political diversity of its members. The organization grew from a Cold War-era confidence-building project into a platform for trade, diplomacy and broader regional forums, but it has never been a supranational government or collective-defence alliance. [1,26]

5. From postcolonial states to the Indo-Pacific order

After the Cold War, economic liberalization, East Asian manufacturing, China’s accession to the World Trade Organization in 2001, ASEAN integration, India’s 1991 reforms and later connectivity initiatives changed the region’s economic map. Global supply chains divided production across multiple countries; ports and industrial zones attracted investment; Singapore, Malaysia, Thailand and later Viet Nam and Indonesia developed different roles in electronics, automotive, commodities, finance, logistics and consumer markets. India expanded services exports, IT, pharmaceuticals, manufacturing ambitions and regional partnerships, but remained less integrated into some East Asian production networks than its geography might suggest.

The phrase Indo-Pacific reflects the growing recognition that the Indian and Pacific Oceans are one connected strategic theatre. India’s Act East Policy, ASEAN’s Indo-Pacific Outlook, the US Indo-Pacific strategy, Japan’s Free and Open Indo-Pacific concept, Australia’s regional strategy and China’s maritime and economic initiatives overlap but do not share the same priorities. ASEAN’s official Outlook emphasizes inclusivity, cooperation, ASEAN-led mechanisms and a maritime perspective; it is partly an attempt to prevent regional order from becoming a binary choice between rival powers. [26]

Contemporary regional order is characterized by economic interdependence and strategic distrust. China is central to most Asian supply chains and remains a major trading partner, investor and infrastructure provider; it is also a military power whose border and maritime disputes concern several regional states. The United States supplies security relationships and advanced technology, but its trade policy can create uncertainty. Japan, Australia, South Korea, India, the EU and Gulf states add strategic options. Regional governments often hedge: they seek economic benefits from China while diversifying security, technology and market relations.

This is not a return to the Cold War in a simple form. There are dense trade links across ideological divides, complex manufacturing networks, sovereign wealth and pension funds, digital platforms, climate risks, and regional organizations that were less central in earlier decades. The same supply-chain connection can be a source of resilience and a vulnerability to sanctions, export controls, shipping disruption or economic coercion.

PART II-INDIA AND THE ELEVEN ASEAN STATES 6. India: continental scale, maritime exposure and federal diversity

6.1 Political system and institutional structure

India is a sovereign, socialist, secular, democratic republic under a written Constitution, with parliamentary government, a federal division of powers, fundamental rights, an independent judiciary in formal design, and competitive multiparty elections. The Supreme Court of India describes the Constitution as binding the legislative, executive and judicial branches and protecting equality before law, religious freedom and constitutional review. In practice, public debate concerns executive power, federal relations, the use of investigative agencies, judicial capacity, media freedom, minority protection and the balance between national security and civil liberties. Formal constitutional status and empirical political practice must be evaluated together. [16,17]

India’s 2024 general election returned Narendra Modi as prime minister for a third term, but the governing coalition depended more on alliance partners than in the previous two parliamentary terms. This changed the parliamentary arithmetic without ending the BJP’s national dominance. Federal politics varies sharply by state; regional parties, caste coalitions, linguistic identities, farmers’

organizations, business networks, religious movements and urban classes shape policy and electoral outcomes. The federal structure means the national government does not control all implementation: education, policing, public health, agriculture, land and local government include important state responsibilities.

6.2 Economic structure and development challenge

India combines a large domestic market, services exports, IT and business-process services, pharmaceuticals, automotive production, engineering, agriculture, energy, construction and a growing digital public infrastructure. The World Bank’s April 2026 update reported FY2026 growth of 7.6% and projected FY2027 growth at 6.6% under its then-current risk assumptions, with higher energy prices and external disruption weighing on the outlook. ADB’s September 2026 outlook separately projected 7.0% growth for India’s FY2026. The differences reflect forecast dates, assumptions and fiscal-year definitions, so the range and risks matter more than false precision. [3,5]

The central development problem is converting aggregate growth into stable, productive work and rising household security. India has a large informal economy, uneven female labour-force participation and employment quality, agricultural dependence, regional inequality, and gaps in health, education and urban services. The World Bank reports a population around 1.46 billion in 2025 and life expectancy of 72 years in 2024, while its gender data portal reports that vulnerable employment in 2025 was substantially higher for women than men. These indicators point to development transitions that GDP growth alone cannot summarize. [18,19]

6.3 Social pluralism and constitutional tensions

India includes many languages, religions, castes, tribes, regional identities and migration histories. Hindu traditions form the majority religious landscape; Muslims constitute the largest religious minority; Sikh, Christian, Buddhist, Jain, Jewish, Zoroastrian and diverse Indigenous traditions also form parts of the country. Caste continues to shape marriage, occupation, social networks and political mobilization despite constitutional prohibitions on untouchability and a range of affirmative-action policies. Scheduled Castes and Scheduled Tribes have reserved representation in legislatures and public institutions, while implementation and the distribution of development gains remain contested.

Freedom House’s 2026 assessment categorizes India as Partly Free and describes concerns about minority rights, institutional checks and civil liberties; this is one external rights assessment and should be read with its stated methodology rather than treated as a universal score of society. India’s official legal order guarantees freedom of religion and equality before law, while public debate continues over the Citizenship (Amendment) Act, personal laws, anti-conversion measures in some states, cow-protection violence, internet shutdowns and the application of security laws. The relationship between constitutional principle and administrative practice is therefore an essential contemporary issue. [20,21]

6.4 Foreign policy: strategic autonomy and partnerships

India’s foreign policy combines strategic autonomy with issue-based partnerships. It participates in the Quad with the United States, Japan and Australia; engages BRICS, SCO, G20, the United Nations and ASEAN-led forums; maintains defence and energy ties with Russia; develops technology and security ties with the United States, Japan, France and others; and seeks economic integration without accepting an exclusive bloc identity. Strategic autonomy is not isolation: it is an effort to retain decision space amid competing pressures.

6.5 China, Pakistan and the northern frontier

India’s relationship with China combines trade interdependence, competition for Asian influence, Himalayan border disputes and military deployments. The 2024 patrolling arrangement around Depsang and Demchok was an important step toward reducing some friction, but it did not settle the boundary. Reports in October 2026 of continued face-offs and disputes over established patrolling patterns underscore how fragile normalization remains. Both sides have incentives to prevent escalation, yet infrastructure, military posture, maps and strategic rivalry continue to affect trust. [22,23]

India-Pakistan relations remain shaped by Kashmir, cross-border militancy, partition memory, water-sharing and nuclear deterrence. After a militant attack in Indian-administered Kashmir in April 2025 and India’s Operation Sindoor in May, a ceasefire held, but bilateral relations remained tense. The Council on Foreign Relations’ tracker, updated 23 October 2026, notes India’s suspension of the Indus Waters Treaty and Pakistan’s warnings about water coercion; a later border incident in October 2026 further sharpened tensions. Claims about individual incidents are disputed by the parties and should not be accepted uncritically. [24]

6.6 India and the Northeast as a gateway

India’s northeastern states connect the country’s mainland to Myanmar, Bangladesh, Bhutan, Nepal and the wider Southeast Asian region. The region’s languages, Indigenous communities, Christian, Hindu, Buddhist and animist traditions, migration histories and borderland economies differ significantly from India’s metropolitan core. Infrastructure is strategically important, but connectivity must account for land rights, ecological sensitivity, local political settlement and conflict. The Kaladan Multi-Modal Transit Transport Project and India-Myanmar-Thailand Trilateral Highway are designed to link Northeast India to Bay of Bengal ports and mainland Southeast Asia. In August 2026, India’s Ministry of Development of North Eastern Region reported completion of the Kaladan waterway component and the handover of the Kalewa-Yargi highway section in Myanmar in October 2025; the project’s remaining segments and the security environment remain critical constraints. [25]

7. Mainland Southeast Asia: Myanmar, Thailand, Laos, Cambodia and Viet Nam

7.1 Myanmar: state fracture and humanitarian crisis

Myanmar sits between India, China, Bangladesh, Thailand and Laos and links the Bay of Bengal to mainland Southeast Asia. Its mountain chains, river valleys, ethnic diversity, resource regions and borderland trade routes have long complicated centralized state-building. The 2021 military coup removed an elected government and triggered nationwide resistance and armed conflict involving the military, ethnic armed organizations and newer resistance structures. The conflict intersects with long-standing ethnic wars, contested federalism, resource extraction, cross-border crime and competing regional interests.

As of 2026, Myanmar remains one of the region’s deepest security and humanitarian crises. The UN’s 2026 Humanitarian Needs and Response Plan estimated 16.2 million people in need of humanitarian aid and more than four million displaced; an OCHA update in July 2026 estimated nearly 3.8 million internally displaced people. The March 2025 earthquake compounded damage and vulnerability. In September 2026, the UN reported that aid partners had reached 3.1 million affected people by the end of June, but access constraints and funding gaps remained. These are different measures-people in need, displaced people and people reached-and must not be conflated. [13,14]

ASEAN’s Five-Point Consensus calls for cessation of violence, dialogue, humanitarian access and a special envoy process. Its implementation has been limited, in part because ASEAN’s norms of non-interference and consensus collide with the scale of violence and member states’ differing interests. The Philippines, as ASEAN chair in 2026, has called for continued action. On 23 October 2026, Thailand’s foreign minister welcomed renewed US engagement with Myanmar’s military-backed government and anticipated substantive discussion at the November ASEAN summit, while saying engagement need not confer legitimacy. The strategic question is whether dialogue can create humanitarian access and political pathways without allowing the armed conflict to be normalized. [8,13,14]

7.2 Thailand: monarchy, military influence and regional position

Thailand’s political system combines an elected parliamentary framework with a powerful monarchy, military institutions, courts and networks of conservative and business elites. Repeated coups and constitutional changes have shaped the limits of electoral authority. The country is a manufacturing, tourism, logistics and automotive hub, and a longstanding US treaty ally with significant economic and diplomatic ties to China. Its position between Myanmar, Laos, Cambodia and Malaysia makes it a key mainland connector, but domestic political competition and regional border disputes can complicate policy continuity.

The Thai-Cambodian land border and overlapping maritime claims are a current flashpoint. After deadly clashes and the end of a 2001 joint development framework in May 2026, Cambodia initiated a conciliation process under UNCLOS for a maritime dispute involving roughly 26,000 square kilometres of the Gulf of Thailand, as reported by Reuters on 23 October 2026. The same report noted little progress and a Thai preference to settle the boundary before discussing resource-sharing. This is a reminder that legal process, energy interests, domestic nationalism and border security may advance at different speeds. [9]

7.3 Laos: landlocked connectivity and debt

Laos is a small, landlocked, one-party socialist republic whose geography is dominated by uplands and the Mekong basin. Hydropower, mining, agriculture, tourism and Chinese-backed rail and infrastructure connections are central to its development strategy. The Laos-China Railway improves access to regional markets, but debt service, currency vulnerability, the distribution of infrastructure benefits, environmental effects of dams and reliance on external finance remain important structural risks. The country seeks to convert its landlocked position into a land-linked one, while the benefits depend on logistics, customs efficiency, skills, and market demand beyond simply laying track.

7.4 Cambodia: garment exports, tourism and political centralization

Cambodia’s economy relies on garments and footwear, construction, tourism, agriculture and growing manufacturing links. The ruling Cambodian People’s Party has maintained a highly centralized political system through a leadership transition from Hun Sen to Hun Manet, while concerns over opposition space, civic freedoms, land disputes and independent media remain material to legal and political analysis. Cambodia’s relations with China support infrastructure and investment, but overconcentration in a narrow set of sectors and exposure to geopolitical shocks create vulnerabilities.

The 2026 Thai-Cambodian border dispute affects border trade, workers, tourism and investor confidence. ADB’s July and September outlooks noted that prolonged border closure would slow Cambodia’s growth outlook, underlining that geopolitical disputes can become real economic shocks at local border economies rather than merely diplomatic abstractions. [3,9]

7.5 Viet Nam: export manufacturing and strategic balancing

Viet Nam combines a one-party Communist Party-led political system with a market-oriented economy, export manufacturing, foreign investment, growing industrial capacity and an increasingly important role in supply-chain diversification. Electronics, machinery, textiles, footwear, furniture, agricultural products and maritime trade tie it closely to East Asian production networks. Its strategic challenge is balancing economic links with China against sovereignty concerns in the South China Sea and broader relationships with the United States, Japan, India, South Korea and Europe.

Viet Nam’s political system has prioritized stability and development, but its legal framework sharply limits independent political opposition, and broad national-security provisions have been used against dissent. Human rights assessments cite restrictions on speech, association and religious or land-rights activism. Its rising manufacturing role also creates new regulatory needs: labour standards, environmental review, intellectual property, data protection, power reliability and the ability to manage industrial clusters without reproducing inequality. [27]

7.6 Mainland patterns and differences

Mainland Southeast Asia should not be treated as one political subregion. Myanmar’s conflict and state fragmentation differ from Thailand’s contested electoral-monarchical system, Laos’s one-party state, Cambodia’s centralization and Viet Nam’s party-led export model. The Mekong basin creates shared hydrological and ecological stakes, while roads, rail, special economic zones and power grids create regional interdependence. Yet political trust, sovereign decision-making and competing external partnerships determine whether connectivity is inclusive or extractive.

8. Maritime Southeast Asia: Indonesia, Malaysia, Singapore, Brunei, the Philippines and Timor-Leste

8.1 Indonesia: scale, archipelagic governance and resource transition

Indonesia is the world’s largest archipelagic state and a major regional actor, with a presidential system, large domestic market, Muslim-majority population and extensive ethnic, linguistic and religious diversity. Its economy includes commodities, manufacturing, services, nickel and other minerals, palm oil, coal, natural gas, fisheries, tourism and digital markets. Its foreign policy tradition emphasizes independence and active participation rather than formal alignment with one bloc, although it increasingly engages major powers on defence, infrastructure, critical minerals and investment.

A current environmental crisis illustrates the link between social policy and regional diplomacy. On 24 October 2026, the Associated Press reported that forest and peatland fires, aggravated by unusually dry conditions, extreme heat and an intensifying El Nino, were producing Southeast Asia’s worst haze in more than a decade. Indonesia’s health ministry reported more than 333,470 acute respiratory illness cases across seven affected provinces since mid-August; students protested for stronger action, and Singapore was pursuing legal action against seven Indonesian companies it blamed for the fires. These reported figures refer to a specific and evolving crisis; they show how domestic land-use governance can generate cross-border health, diplomatic and economic consequences. [10]

8.2 Malaysia: plural society and export integration

Malaysia combines a constitutional monarchy, parliamentary government, federal structure and a complex political balance among Malay, Chinese, Indian, Indigenous and other communities. Islam has a special constitutional position, while religious and civil-law institutions overlap in areas such as family law. The economy spans electronics and electrical exports, petroleum and gas, palm oil, finance, manufacturing, tourism and services. Malaysia’s location on the Strait of Malacca and its role in electronics supply chains make it a significant middle power, but domestic ethnic and religious politics, labour migration, inequality and ecological pressures remain important governance issues.

8.3 Singapore: global hub, constrained space

Singapore is a highly urbanized city-state, parliamentary republic and global hub for shipping, finance, aviation, advanced manufacturing, data centres and dispute resolution. It relies on trade and imported food, energy and water, giving resilience planning a strategic importance beyond its size. The People’s Action Party has dominated national politics since independence, and the system combines effective state capacity with restrictions on some forms of political competition, media pluralism and public assembly. Singapore’s role in ASEAN is often that of a rules-focused broker, but its economic exposure to regional instability means that maritime security, digital trust and predictable trade are national interests.

8.4 Brunei Darussalam: energy and monarchy

Brunei is a small, oil- and gas-producing sultanate with a high-income but hydrocarbon-dependent economy. Its political system is an absolute monarchy; Islam is the official religion and Malay identity is central to national ideology, while non-Muslim communities are present. Energy prices, diversification, migrant labour, fiscal sustainability and the South China Sea shape policy. Brunei is cautious in public diplomacy and has claims in the South China Sea, but generally prefers negotiation and ASEAN processes to open confrontation.

8.5 Philippines: archipelagic democracy and alliance politics

The Philippines is a presidential democracy with a competitive but highly personalized political system, strong family networks, an active press and civil society, and longstanding challenges around inequality, political dynasties, regional insurgencies and rule-of-law enforcement. Its society is predominantly Christian, with Muslim communities concentrated especially in Mindanao and the Sulu archipelago, alongside Indigenous and regional identities. The economy draws on services, remittances, electronics, manufacturing, tourism, agriculture and a large overseas workforce.

The Philippines is a frontline claimant in the South China Sea and a US treaty ally. On 20 October 2026, the Associated Press reported that Manila summoned China’s ambassador after remarks it interpreted as a threat to use force; Beijing rejected Manila’s characterization and described the response as an overreaction. The incident occurred amid expanded Philippine defence cooperation with the United States and other partners, Chinese military activity, and continuing ASEAN negotiations over a Code of Conduct. The episode highlights the challenge of turning UNCLOS-based legal positions into a stable maritime order when coast guard and naval encounters are politically charged. [12,15]

8.6 Timor-Leste: the newest ASEAN member

Timor-Leste is a small, young state in the eastern Indonesian archipelago with a history shaped by Portuguese colonial rule, Indonesian occupation, a UN-supervised transition and independence in 2002. Catholicism is central to public culture, alongside local practices and linguistic diversity. Petroleum revenues have been important, but long-run development depends on fiscal sustainability, human capital, agriculture, job creation, infrastructure and diversification. Its admission as ASEAN’s eleventh member on 26 October 2025 was a milestone for regional inclusivity but also brings the practical task of implementing ASEAN legal instruments, participating in the three community pillars, and building regulatory and diplomatic capacity. [1,2]

8.7 Maritime region: integration and uneven capacity

The maritime states differ in size and strategy but are linked by shipping, fisheries, energy, migratory labour, undersea cables and shared ecosystems. Indonesia and the Philippines govern huge archipelagos; Singapore concentrates global logistics and finance; Malaysia combines peninsular and Bornean territories; Brunei depends on hydrocarbons; Timor-Leste is building institutions and diversifying. Their different capacities affect responses to piracy, illegal fishing, haze, maritime claims, disaster relief and digital integration.

9. Country comparison matrix: political systems, economies and strategic issues

This matrix is an orientation, not a full constitutional description or a ranking. Political regimes change, laws differ in enforcement, and individual countries contain major internal differences. Timor-Leste is included because ASEAN admitted it in October 2025; Myanmar’s inclusion does not imply that ASEAN has resolved the crisis of its representation and political legitimacy. [1,2,8,9,27]

10. India’s wider neighbourhood: Bangladesh, Nepal, Bhutan, Sri Lanka and Maldives

Although not Southeast Asian countries, India’s immediate South Asian neighbours affect how New Delhi approaches the Bay of Bengal, Himalayan connectivity, maritime security, migration and regional diplomacy. India cannot effectively pursue an eastward strategy while ignoring instability, distrust or infrastructure gaps in its western and northern neighbourhood.

10.1 Bangladesh: geography, political change and interdependence

Bangladesh occupies the Ganges-Brahmaputra-Meghna delta, one of the world’s most densely populated and climate-exposed regions. It is deeply connected to India through borders, rivers, energy, transport, trade, culture and migration, while also maintaining important ties with China and other partners. The relationship involves border security, enclaves resolved by a 2015 agreement, river-water sharing including the unresolved Teesta question, transit, energy, textiles, and concern over cross-border violence and migration.

The political upheaval of 2024 changed bilateral relations when Sheikh Hasina left for India after a mass uprising. On 27 April 2026, Reuters reported that India named Dinesh Trivedi as its next high commissioner to Bangladesh, in a signal that New Delhi sought to rebuild ties as the BNP under Tarique Rahman came to power after a February election. Bangladesh’s request for fuel, fertilizer, energy cooperation and easier travel represented practical incentives for rapprochement, while India’s position on Hasina’s future remained a major source of tension. The situation is dynamic and should be read as an evolving diplomatic reset rather than a settled reconciliation. [28]

10.2 Nepal and Bhutan: Himalayan connectivity and hydropower

Nepal’s geography, open-border relationship with India, hydropower potential, labour migration, tourism and political transition make it strategically important. Its relations with both India and China reflect a desire for autonomy, infrastructure and economic opportunity. Bhutan’s close links with India include hydropower, trade, development assistance and security, while Bhutan also manages its own negotiations and concerns along the Himalayan frontier with China. Himalayan diplomacy must consider water systems, mountain ecology, border communities, disaster response and the risk of infrastructure becoming securitized.

10.3 Sri Lanka and Maldives: maritime neighbourhood

Sri Lanka sits astride Indian Ocean routes and has important links to India through geography, trade, religion, migration and security. Its debt and balance-of-payments crisis in 2022 exposed the vulnerability of external borrowing, tourism dependence, currency pressures and governance failures; subsequent reforms and political changes have occurred under continuing fiscal constraints. The Maldives is a strategically placed archipelago near Indian Ocean sea lanes. Tourism and fisheries are vital, while debt, climate change, coastal protection and choices about security partnerships shape domestic politics. The two countries show why India regards the Indian Ocean as a neighbourhood, not a distant global space.

10.4 Regional cooperation and limits

SAARC has been constrained by India-Pakistan rivalry, while BIMSTEC offers a Bay of Bengal framework connecting South and Southeast Asia. Connectivity projects can create mutual benefit but also raise issues of debt, environmental impact, local consent and strategic competition. India’s regional strategy succeeds only when neighbours perceive trade, transport, energy and security cooperation as useful to their own development, not simply as tools for Indian influence.

PART III-CONTEMPORARY GEOPOLITICS AND SECURITY 11. India-ASEAN relations: Look East, Act East and practical

connectivity

11.1 From Look East to Act East

India’s Look East Policy, initiated in the early 1990s, reflected economic liberalization and a strategic effort to reconnect with East and Southeast Asia after the Cold War. The Act East Policy, announced in 2014, widened the ambition toward connectivity, commerce, culture, strategic partnerships and the development of India’s Northeast. India and ASEAN became strategic partners and continue to cooperate through trade, summits, maritime forums, education and people-to-people programmes. India does not have the same institutional integration with ASEAN as China or the major East Asian production economies, so the challenge is to translate diplomacy into reliable logistics, investment and business linkages. [21,25,29]

11.2 Trade and investment

ASEAN’s official economic-relations page reports two-way merchandise trade with India of US$106.83 billion in calendar year 2024 and Indian FDI inflows to ASEAN of US$3.5 billion. India’s Department of Commerce reports a different fiscal-year total of US$120.87 billion for 2023-24. These figures should not be treated as contradictory without checking definitions, source, timing and statistical treatment; calendar-year ASEAN data and India’s fiscal-year trade data cover different periods. ASEAN was India’s eighth-largest trading partner and one of the key investment destinations among dialogue partners according to the ASEAN Secretariat. [21,22]

The ASEAN-India Trade in Goods Agreement (AITIGA) entered into force in 2010, and the parties have been reviewing it to improve effectiveness and address concerns about trade imbalances, tariff schedules, rules of origin and market access. India’s Ministry of External Affairs noted in March 2026 that the review was continuing, alongside maritime cooperation. The policy challenge is not only to increase trade totals but to raise the Indian share of regional value chains, reduce logistics costs, improve customs reliability, support small firms and prevent protection measures from undermining the trust needed for investment. [21,29]

11.3 Connectivity: ports, roads, rivers and people

The India-Myanmar-Thailand Trilateral Highway and Kaladan Multi-Modal Transit Transport Project are intended to reduce the geographic isolation of India’s Northeast and connect it to Myanmar and mainland Southeast Asia. Their strategic logic is strong: land routes can complement sea lanes and create local business opportunities. But implementation faces difficult terrain, security risk in Myanmar, construction delays, customs coordination, funding and local environmental concerns. A road is not a functioning corridor unless border procedures, warehousing, insurance, security, service firms and reliable demand also exist. [25]

Maritime links are equally important. Indian ports on the east coast connect to Singapore, Port Klang, Jakarta, Ho Chi Minh City, Manila and other hubs. Coastal shipping, container services, cruise and tourism links, fisheries, search-and-rescue and maritime domain awareness can deepen cooperation. Yet connectivity can be uneven: major ports may benefit while inland or border communities bear land acquisition and environmental costs. Inclusive design means local employment, safeguards, transparent procurement and cross-border customs reform.

11.4 Culture, education and diaspora

Cultural ties provide a deeper foundation than summit diplomacy alone: Buddhist heritage, Hindu-Buddhist monuments, Sanskrit and Pali influence, maritime migration, Indian cinema, yoga, food, language and long-standing Indian-origin communities are visible across the region. These ties should be approached as reciprocal cultural history rather than a claim that contemporary Southeast Asian identities derive only from India. Student exchange, joint research, heritage conservation, tourism and digital cultural industries can support mutual understanding when they respect local perspectives.

11.5 What prevents deeper partnership?

Trade barriers, slow infrastructure completion, limited regional production networks, domestic protectionism, visa and payments frictions, uneven private-sector awareness, and Myanmar’s instability all constrain India-ASEAN relations. India left the Regional Comprehensive Economic Partnership negotiations in 2019, reflecting concerns over import surges and trade asymmetries. That decision preserved policy space but may also have limited India’s full integration into an East Asian trade architecture. India-ASEAN cooperation can deepen without identical choices on every trade agreement, but both sides need credible market access, logistics and stable regulatory arrangements.

12. China, the United States and strategic hedging

12.1 China as a central economic partner and strategic competitor

China is central to regional trade, infrastructure, manufacturing, tourism and investment. Chinese demand and supply networks have helped develop Southeast Asian manufacturing, while Chinese finance has funded roads, railways, ports and energy projects. At the same time, territorial and maritime disputes, economic coercion concerns, technology dependencies and military modernization generate strategic anxiety. It is therefore misleading to portray Southeast Asian states as either simply pro-China or anti-China; most seek benefits while maintaining room to resist pressure.

12.2 United States and partner networks

The United States remains a major military, technological, financial and diplomatic actor. Its treaty alliance with the Philippines, security partnership with Thailand, relations with Singapore and Indonesia, and wider regional initiatives shape deterrence. Japan, Australia and South Korea contribute investment, aid, technology, defence and infrastructure. India is viewed by some states as an additional strategic partner because of its size, Indian Ocean location and strategic autonomy, but India’s capacity to deliver infrastructure and security goods is not unlimited.

12.3 Strategic hedging

Strategic hedging is a portfolio of policies rather than indecision. A state may trade extensively with China, purchase advanced technology from multiple suppliers, cooperate with the United States on defence, and participate in ASEAN forums to preserve regional autonomy. The mix varies. Viet Nam is careful about sovereignty yet economically integrated with China; Indonesia emphasizes non-alignment and ASEAN centrality; Singapore stresses rules and maritime access; the Philippines has strengthened US defence ties; Malaysia tends to prioritize economic pragmatism and diplomacy. The choices are shaped by domestic politics, history, geography and perceptions of threat.

12.4 Supply chains and geoeconomic competition

Export controls, sanctions, tariff changes, industrial subsidies and national-security restrictions have turned supply chains into strategic assets. Electronics, semiconductors, batteries, EVs, critical minerals, pharmaceuticals, cloud services and undersea cables can become targets of competition. Southeast Asia benefits when firms diversify production, but it also faces pressure to comply with competing rules of origin, data rules and security restrictions. India seeks a greater manufacturing role, while requiring workforce skills, reliable power, logistics and predictable regulation to convert incentives into productivity.

12.5 ASEAN centrality under stress

ASEAN centrality means that ASEAN-led forums should anchor regional dialogue, not that ASEAN can compel every major power to comply. Consensus gives each member a voice but can constrain action when interests diverge, as Myanmar demonstrates. The ASEAN Outlook on the Indo-Pacific emphasizes cooperation over rivalry, openness, inclusivity, sovereignty and existing ASEAN-led mechanisms. It is an attempt to create space for dialogue, but it cannot remove the strategic competition that members must manage. [26]

13. South China Sea: law, power and maritime claims

The South China Sea is a strategic maritime basin connecting the Pacific and Indian Ocean systems. It carries commercial shipping, hosts fisheries and hydrocarbon resources, and contains reefs, shoals, islands and other features whose legal status affects maritime entitlements. China claims broad historic rights within its nine-dash-line map; the Philippines, Viet Nam, Malaysia, Brunei and Taiwan have overlapping claims or interests. Claims differ and should not be described as identical. The sea’s importance lies in the interaction of sovereignty, UNCLOS, fisheries, energy, military access, national prestige and economic dependence.

13.1 UNCLOS and the 2016 arbitral award

The Philippines initiated arbitral proceedings against China under the United Nations Convention on the Law of the Sea. The tribunal’s 12 July 2016 award addressed historic rights, maritime entitlements, the status of maritime features and certain conduct. It found that there was no legal basis for China’s claims to historic rights beyond UNCLOS entitlements where they exceeded the convention, and it addressed the classification of features and environmental obligations. It did not rule on sovereignty over land territory or draw every maritime boundary. China rejected the award and maintains that the tribunal lacked jurisdiction and that the award is null and void; the Philippines and many other states regard it as legally binding under UNCLOS. [30]

13.2 Coast guards and grey-zone pressure

Many incidents involve coast guards, maritime militia, fishing fleets and water-cannon or obstruction tactics rather than conventional naval battle. Such operations can shift facts on the water while staying below the threshold of open war. They create a legal and political dilemma for smaller states: they must document incidents, preserve resupply access, sustain domestic resolve and avoid escalation. The Philippines’ expanded defence cooperation and public documentation strategy reflect one response; other claimants often favour quieter diplomacy to preserve economic ties.

13.3 Code of Conduct and ASEAN diplomacy

ASEAN and China have negotiated a Code of Conduct for years, but key questions include legal bindingness, scope, geographic coverage, dispute resolution, enforcement and compatibility with international law. The Philippines, as ASEAN chair in 2026, has prioritized progress toward a substantive Code. Analysts note that a chair’s ambition cannot by itself resolve differences between China and claimants or ASEAN’s consensus constraints. A weak text may provide political optics without changing conduct; an overly ambitious text may remain unfinished. [31]

13.4 India’s interests

India is not a territorial claimant in the South China Sea, but it has interests in freedom of navigation, lawful maritime commerce, energy flows, the safety of its nationals, and relations with Viet Nam, Singapore, Indonesia, Malaysia and the Philippines. India’s naval presence and exercises, defence relationships, and public support for UNCLOS-based norms reflect these interests. India must also avoid presenting the maritime issue as simply an anti-China coalition, since regional states have different risk tolerances and commercial dependencies.

13.5 Practical risk reduction

Risk reduction requires reliable hotlines, incident-prevention protocols, search-and-rescue and coast-guard communication, transparency around exercises, environmental cooperation and mechanisms for fisheries and resource management. International law can create common standards; it cannot enforce itself. A durable settlement would require political decisions by states that disagree about sovereignty, so interim rules and crisis-management arrangements remain vital.

14. Myanmar: conflict, diplomacy and humanitarian fallout

Myanmar’s crisis is central to regional security because it borders India, China, Bangladesh, Thailand and Laos, and because conflict generates refugees, arms flows, illicit trade, narcotics, scam compounds, environmental damage and humanitarian emergencies. The conflict grew from the 2021 coup but interacts with decades of ethnic armed resistance and unresolved questions of federalism, land, resource governance and national identity. A policy that treats Myanmar only as a competition among foreign powers misses the agency of domestic resistance groups and ethnic organizations; a policy that treats it only as domestic politics misses the regional and transnational consequences.

14.1 Humanitarian metrics and limits of access

The UN’s 2026 humanitarian plan estimated 16.2 million people in need and more than four million people displaced, while its July 2026 update estimated almost 3.8 million internally displaced. The September update described assistance reaching 3.1 million people by 30 June, a measure of delivery rather than the disappearance of need. Hostilities, movement restrictions, administrative obstacles, funding gaps and destruction of infrastructure hinder consistent assistance. Figures change quickly, and the geography of access can be politically constrained. [13,14]

14.2 ASEAN’s dilemma

The Five-Point Consensus remains ASEAN’s primary framework, but implementation has not stopped violence. Member states disagree on engagement, representation and the conditions under which military authorities should be recognized. Thailand’s foreign minister said on 23 October 2026 that renewed US engagement with Myanmar’s military-backed government might help encourage peaceful resolution without legitimizing it; he also said discussions at the November ASEAN summit could be substantive. These statements indicate a possible shift in diplomatic tactics, not evidence that the conflict is nearing settlement. [8]

14.3 India’s border and connectivity interests

India shares a long, difficult border with Myanmar and has security concerns involving insurgent movement, refugees, arms and narcotics, while also seeking trade and connectivity to Southeast Asia. The Kaladan project and Trilateral Highway can be strategically valuable, but conflict in Rakhine and other frontier areas undermines reliability. India must balance humanitarian obligations, border management, relations with Myanmar’s authorities, engagement with affected ethnic communities and the objective of connectivity. Roads without security, local legitimacy and predictable customs cannot deliver their intended strategic returns.

14.4 Conditions for a durable settlement

A durable settlement would likely require a credible reduction in violence, humanitarian access, participation by a broad range of domestic actors, protection for ethnic communities, and arrangements addressing federalism and resource control. No single external actor appears able to impose such an outcome. ASEAN can provide diplomatic space, neighbouring states can reduce cross-border harm, and international partners can coordinate aid and pressure, but domestic political legitimacy remains indispensable.

15. Himalayan borders, India-Pakistan and India’s regional security dilemmas

15.1 India-China: border stability without strategic resolution

The 2024 arrangements around Depsang and Demchok reduced certain friction but did not settle the Line of Actual Control. Military infrastructure, patrol patterns, maps, strategic competition and trust deficits remain important. October 2026 reports of face-offs in Arunachal Pradesh and Indian concerns about patrol deviations illustrate how local incidents can undermine larger diplomatic normalization. Both states have incentives to maintain trade and prevent war, but the boundary question is inseparable from power and national identity. [22,23]

15.2 India-Pakistan and nuclear deterrence

The India-Pakistan security relationship combines Kashmir, militancy, military signaling, water, airspace, trade and nuclear deterrence. A ceasefire can limit casualties without resolving underlying disputes. The suspension of the Indus Waters Treaty after the 2025 crisis heightened concern about water as a tool of coercion; the treaty’s future has implications for regional hydrology and diplomacy. Reported incidents in 2026 further show that limited border events can quickly produce diplomatic escalations. The report treats claims from both states as contested unless independently verified. [24]

15.3 Northeast India’s security and identity

India’s Northeast is a borderland with many Indigenous peoples, languages, religions and political histories, including Christian-majority areas, Hindu and Buddhist communities, and local traditions. Security policy must account for insurgencies and cross-border networks, but also for ethnic representation, land rights, autonomous councils, migration and development. A purely infrastructural or militarized approach risks overlooking the political settlements that enable roads, trade and local economies to function sustainably.

15.4 Regional conflict diffusion

Security crises spread across borders through refugees, informal trade, weapons, fuel, criminal networks and commodity markets. Myanmar’s war affects border areas in India and Thailand; India-Pakistan tension affects airspace, energy and regional diplomacy; South China Sea tensions affect shipping risk and investment planning; and the Thai-Cambodian border closure harms workers, border markets and tourism. The region’s high interconnectedness makes crisis prevention a collective interest even when formal institutions remain weak.

16. Maritime security, chokepoints, piracy and coast guard cooperation

The Indian Ocean and Southeast Asian seas sustain a large proportion of global trade, energy shipments, container traffic and undersea digital cables. The Malacca-Singapore strait is a key route between the Indian and Pacific Oceans, while the Sunda and Lombok routes provide alternatives through Indonesia. The Andaman Sea and Bay of Bengal are strategically important for India, Myanmar, Thailand, Malaysia and Indonesia. Sea-lane security includes more than naval deterrence: piracy and robbery, illegal fishing, trafficking, search and rescue, environmental emergencies, port cybersecurity and disaster relief all require routine cooperation.

16.1 India’s naval role

India’s navy and coast guard protect sea lines of communication, conduct humanitarian assistance and disaster relief, support anti-piracy operations, and build maritime partnerships with Southeast Asian countries. The Andaman and Nicobar Command provides a geographically significant presence near the western approaches to Malacca. India’s maritime diplomacy is more credible when it combines exercises with practical public goods: hydrographic cooperation, maritime domain awareness, rescue capacity, pollution response and training.

16.2 ASEAN maritime cooperation

ASEAN members do not share one maritime threat assessment. Singapore prioritizes sea-lane access; Indonesia emphasizes sovereignty over archipelagic waters; Malaysia and Brunei balance resources and claims; the Philippines is focused on South China Sea pressure; Viet Nam has major sovereignty concerns; Thailand prioritizes coastal and Gulf interests; and Cambodia’s maritime policy is linked to its wider regional diplomacy. ASEAN mechanisms can coordinate dialogue, but operational cooperation often occurs through bilateral or minilateral arrangements. The goal should be to ensure that such cooperation complements rather than undermines ASEAN-wide trust.

16.3 Ports, cables and the digital maritime layer

Modern maritime power includes ports, ship registries, insurance, undersea cables, satellite communication, port community systems and digital customs. A disruption at a major port or cable landing station can affect manufacturing and financial activity hundreds of kilometres away. Cybersecurity, data integrity, redundancy, and clear legal responsibility are therefore part of maritime resilience. Strategic investment screening must be proportionate: it should address genuine security risks without turning every commercial project into a geopolitical contest.

16.4 Piracy, trafficking and illicit economies

Piracy and armed robbery at sea have declined in some corridors through cooperation but remain concerns; trafficking, illegal fishing, narcotics, arms and human smuggling also exploit maritime complexity. The region’s waters are difficult to police because they cross national jurisdictions and contain many small islands and informal ports. Coast guards, customs, fisheries agencies, prosecutors and communities need information-sharing and legal procedures, not only more patrol vessels.

17. Regional institutions and economic architecture

17.1 ASEAN’s institutional design

ASEAN’s model is built around consultation, consensus, non-interference and gradual integration. This protects national sovereignty and enables states with different systems to stay engaged, but it can make enforceable collective responses difficult. ASEAN-led forums include the East Asia Summit, ASEAN Regional Forum, ASEAN Defence Ministers’ Meeting-Plus and ASEAN Plus One mechanisms. The ASEAN Outlook on the Indo-Pacific places ASEAN centrality within a wider approach to cooperation across the Indian and Pacific Oceans. [26]

17.2 India’s place in ASEAN-led forums

India participates in the East Asia Summit, ASEAN Regional Forum, ASEAN Defence Ministers’ Meeting-Plus and ASEAN-India mechanisms. Its approach seeks to strengthen maritime cooperation, resilient supply chains, digital and physical connectivity, education, tourism, health, disaster response and development. The difficulty is implementation: diplomatic communiques need to become transport corridors, customs improvements, skills programmes, standard-setting and investment outcomes. India must also recognize that each ASEAN member evaluates its relations with China, the United States, Japan and India through its own security calculations.

17.3 RCEP, CPTPP, IPEF and AITIGA

The Regional Comprehensive Economic Partnership (RCEP) links ASEAN with China, Japan, South Korea, Australia and New Zealand and is a major regional trade architecture. India chose not to join RCEP in 2019, citing concerns about import surges, protection of sensitive sectors and trade imbalances. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) includes several Southeast Asian members but not all; the Indo-Pacific Economic Framework for Prosperity focuses on selected economic and supply-chain issues rather than a conventional tariff-cutting free-trade area. AITIGA is the main ASEAN-India goods agreement, and its review seeks to improve effectiveness.

17.4 ASEAN Digital Economy Framework Agreement

On 1 June 2026, ASEAN’s Senior Economic Officials announced that negotiations on the Digital Economy Framework Agreement had resolved outstanding issues at a meeting in Manila in late May. ASEAN framed the agreement as a step toward a digitally integrated, secure, interoperable and inclusive regional economy, with a potential digital economy of up to US$2 trillion by 2030 under successful implementation. The estimate is not a guarantee and depends on adoption, investment, trust, skills and governance. DEFA could influence e-commerce, digital payments, cross-border data, cybersecurity, consumer protections and support for small businesses. [11]

17.5 Law, trade rules and industrial policy

Trade agreements increasingly regulate services, data, subsidies, standards, procurement, rules of origin and supply-chain resilience as much as tariffs. The region must reconcile national industrial policies with the practical needs of cross-border production. India’s policy challenge is to build export competitiveness and reduce logistics frictions while retaining legitimate policy space for agriculture, small industry and development. ASEAN’s challenge is to deepen integration while avoiding a race to the bottom in labour, environmental and fiscal regulation.

17.6 What regionalism can and cannot do

Regional institutions can lower transaction costs, provide crisis channels, establish common standards, and create space for dialogue among competing powers. They cannot abolish sovereignty disputes, force political reconciliation in Myanmar, guarantee free trade under geoeconomic rivalry or replace domestic institutions. Successful regionalism depends on credible national implementation, predictable law, transparency and public legitimacy as well as summits.

PART IV-ECONOMY, SOCIETY, RELIGION AND LAW 18. Regional political economy and supply-chain transformation

18.1 The macroeconomic picture

The region is economically dynamic but heterogeneous. ADB’s September 2026 Asian Development Outlook projects developing Southeast Asia’s GDP to expand by 4.7% in 2026 and 4.9% in 2027, while South Asia is forecast to grow 6.4% in 2026 and 6.5% in 2027. These aggregates mask divergent country trajectories: Viet Nam is projected to remain relatively strong; Indonesia’s domestic demand supports growth; Malaysia benefits from manufacturing and exports; Thailand is more subdued; the Philippines faces consumption and investment headwinds; and Myanmar’s forecast is shaped by conflict and disaster recovery. [3,4]

The same ADB report highlights regional exposure to higher energy prices, trade uncertainty, weaker external demand, climate hazards and financial conditions. India’s economy has greater weight in the South Asian aggregate, but its growth is exposed to imported energy and weak productivity or employment outcomes in parts of the economy. Forecasts are scenario-based and can change quickly; the appropriate method is to state the forecast date and assumptions rather than quote one number as a timeless fact.

18.2 Production networks and manufacturing

Southeast Asia’s manufacturing strengths include electronics, semiconductors, automotive components, electrical equipment, textiles, footwear, machinery, processed food and consumer goods. Different economies occupy different parts of the chain: Singapore concentrates high-value services and advanced logistics; Malaysia and Viet Nam have electronics and manufacturing clusters; Thailand has automotive and industrial supply chains; Indonesia combines a large domestic market with nickel and resource industries; the Philippines contributes electronics and services; Cambodia relies substantially on garments and footwear. India seeks to expand electronics, semiconductors, pharmaceuticals, defence production and industrial components but must improve reliability of logistics, power, workforce skills and supplier depth.

18.3 China-plus-one and geoeconomic shifts

Companies diversify production to reduce concentration risk, respond to tariffs, secure access to different markets or meet rules-of-origin requirements. Southeast Asian states have attracted investment as alternatives or complements to China, but many still rely on Chinese intermediate goods and capital equipment. Supply-chain relocation can create jobs and technology transfer, while also creating dependencies and environmental costs. India may benefit if it offers scale, competitive inputs, logistics and clear regulation; incentives alone cannot compensate for delays, unreliable infrastructure or weak skills.

18.4 Commodities, energy and critical minerals

Coal, oil and gas, palm oil, rubber, rice, nickel, bauxite, copper, timber, fish and other resources remain important. Indonesia’s nickel policy connects mineral supply with electric-vehicle batteries and industrial upgrading; Brunei and Malaysia remain significant energy actors; Laos exports hydropower; Myanmar holds gas and minerals but conflict complicates extraction; India is exposed to imported oil and gas while expanding renewable energy and manufacturing. Critical-mineral strategies can support industrial value addition but risk deforestation, pollution, labour abuses and overdependence on one export commodity.

18.5 Agriculture and food security

Rice remains central to livelihoods, food security and politics in many parts of Southeast Asia, while Indian agriculture supports a vast population and a large rural workforce. Trade, procurement, subsidies, irrigation, fertilizer availability, climate risk and storage determine the stability of food systems. Export restrictions may protect domestic consumers in the short term but can transmit price shocks to neighbours. Drought, floods and energy shocks may affect fertilizer, transport and cold chains, linking agricultural policy to geopolitics.

18.6 Informality, inequality and state capacity

GDP growth does not automatically reduce inequality or create secure employment. Informal workers, rural households, migrant labourers, women, ethnic minorities and small enterprises often have less bargaining power, social insurance and access to finance. Welfare systems differ sharply: some states offer universal or near-universal services, while others rely on family networks, migrant remittances or narrowly targeted programmes. The region’s long-run competitiveness depends on education, public health, labour rights, reliable legal institutions and the distribution of productivity gains, not just export volumes.

18.7 India-ASEAN trade: opportunity and friction

India-ASEAN trade is large enough to matter strategically but smaller than the region’s deepest East Asian production networks. ASEAN’s calendar-2024 figure of US$106.83 billion in merchandise trade and India’s fiscal 2023-24 figure of US$120.87 billion reflect different statistical periods. India’s leading trading partners in ASEAN include Singapore, Indonesia, Malaysia, Viet Nam and Thailand. Exports from India include fuels, chemicals, meat, gems, engineering goods and machinery; imports include coal, electronics, vegetable oils, chemicals and metals. This trade profile reflects complementarity but also exposes India to energy and intermediate-goods dependencies. [21,22]

Practical gains would come from reducing non-tariff barriers, improving rules of origin and customs, expanding standards recognition, improving maritime and land connections, supporting smaller firms, increasing services trade and building trusted digital payment and logistics links. The AITIGA review offers an opportunity to address perceived asymmetries without abandoning the broader strategic interest in integration.

19. Social structure: caste, class, ethnicity, migration and gender

19.1 Demographic transition and urbanization

India and Southeast Asia are undergoing different demographic transitions. India remains very large and relatively young, with strong regional variation in fertility, health and urbanization. Several Southeast Asian economies face aging populations and lower fertility, while others remain younger and have large informal or rural labour forces. Cities such as Mumbai, Delhi, Bengaluru, Jakarta, Manila, Bangkok, Ho Chi Minh City and Singapore concentrate services, jobs, education and infrastructure, but also traffic, pollution, housing pressure, flooding and social inequality. Urbanization brings productivity only if transport, housing, utilities and legal planning can keep pace.

19.2 Caste, ethnicity and Indigenous status

In India, caste and tribe continue to shape social life and access to land, work, education, political representation and justice, even as constitutional and statutory remedies seek to reduce discrimination. In Southeast Asia, ethnicity and indigeneity matter in different ways: Karen, Kachin, Rakhine, Rohingya and other communities in Myanmar; Malay, Chinese, Indian and Indigenous communities in Malaysia; Moro and Lumad communities in the Philippines; Indigenous peoples in Indonesia, Viet Nam, Laos, Thailand and Cambodia; and diverse local groups across the region. These are not interchangeable categories. Their histories, land rights, citizenship, language, religion and experiences of state-building differ.

19.3 Labour migration and diaspora

Migration connects rural households to cities and international markets. Indian workers and professionals travel throughout the Gulf and Asia; Southeast Asian workers migrate to Singapore, Malaysia, Thailand, South Korea, Japan, Taiwan, the Gulf and beyond. Remittances support household spending and foreign exchange, but migrants can face wage theft, recruitment debt, passport retention, abuse, insecure status and limited access to justice. Regional migration frameworks remain fragmented, and refugee protection is particularly weak in some jurisdictions.

19.4 Gender and employment

Women’s labour-market outcomes are shaped by care work, transport safety, occupational segregation, legal protections, informal employment, childcare and cultural norms. India’s World Bank gender data page reports higher vulnerable employment among women than men in 2025, reflecting the prevalence of work without secure contracts or social protection. Across Southeast Asia, female participation differs between countries and sectors; export factories may create paid employment while maintaining low wages and limited advancement, and domestic workers can be particularly vulnerable to exclusion from labour protections. The region’s competitiveness depends on reducing gender barriers, not only attracting capital.

19.5 Class, education and mobility

Education and digital services create new opportunities, but the quality and cost of schooling, rural connectivity, language, family wealth and urban location shape who can benefit. Elite universities and professional networks coexist with crowded classrooms, uneven vocational training and gaps in basic learning. Skills policies must be connected to real labour demand in manufacturing, healthcare, logistics, construction, care work, digital services and green industries. Growth strategies fail socially when they create islands of modern employment without broad-based capability.

19.6 Refugees, displacement and statelessness

The region hosts refugees, asylum seekers, internally displaced people, stateless populations and migrants in precarious legal positions. UNHCR’s Asia-Pacific report published in August 2026 recorded 17.6 million people forcibly displaced, stateless, returned or otherwise supported across the wider region by the end of 2025; this is a regional assistance grouping, not a count of Southeast Asia alone. The Myanmar crisis and the Rohingya situation are major drivers of displacement, while other vulnerabilities arise from conflict, persecution, disaster and documentation gaps. Statelessness limits access to education, healthcare, lawful work, travel and justice. [32]

19.7 Social cohesion and information environments

Social media allows rapid mobilization and greater visibility for marginalized groups, but can also spread disinformation, communal hatred, conspiracy theories, scams and electoral manipulation. Governments vary in their response, from transparent regulation and independent oversight to broad censorship and criminal restrictions. Platform governance must balance safety, privacy, freedom of expression and due process. Digital inclusion is a social issue: people without connectivity, language access or digital literacy are excluded from both economic opportunity and public debate.

20. Religion, language, identity and cultural pluralism

20.1 India: religious diversity and constitutional secularism

India’s religious landscape includes Hindu traditions, Islam, Christianity, Sikhism, Buddhism, Jainism, Judaism, Zoroastrianism and many Indigenous and local traditions. Religious practice also intersects with region, caste, language, family, pilgrimage, food, festivals and political mobilization. The Constitution protects freedom of conscience and religion while allowing regulation of secular activities and social reform. Debates arise around personal law, conversion, religious-site claims, minority rights, citizenship, hate speech and the public role of religion. These debates should be described through legal provisions, political practice and the views of affected communities rather than treated as evidence of a single uniform social attitude.

20.2 Southeast Asia’s religious geography

Theravada Buddhism is institutionally central in Thailand, Myanmar, Cambodia and Laos, though these societies also contain Muslims, Christians and Indigenous traditions. Indonesia and Malaysia have Muslim majorities and diverse minorities; Brunei has an Islamic monarchy; the Philippines and Timor-Leste are predominantly Christian; Singapore is highly plural, with Buddhist, Christian, Muslim, Hindu, Taoist and nonreligious populations; Viet Nam combines Buddhist, folk, ancestor and other traditions, alongside Christianity and large numbers who report no formal religion. These national summaries describe broad patterns, not uniform belief or practice.

20.3 Religion and nationalism

Religion can support solidarity, ethical action and civil society, but it can also become a language of exclusion in electoral competition or nationalist projects. Buddhist majoritarian politics in Myanmar and Sri Lanka, Muslim identity politics in parts of Indonesia and Malaysia, Hindu nationalist mobilization in India, Christian political networks in the Philippines, and state regulation of religion in Viet Nam each have distinct histories. Comparative analysis should not collapse these into one pan-Asian conflict: the legal and political structures differ, as do histories of majority formation and minority status.

20.4 Language and political identity

Language policy is often a foundational state-building issue. India recognizes multiple scheduled languages and uses Hindi and English at the Union level in different capacities, with state languages shaping education and administration. Southeast Asia includes Malay/Indonesian, Thai, Vietnamese, Khmer, Lao, Burmese, Filipino, Tetum, English, Chinese varieties, Indigenous languages and many others. Language can unify administration and national identity, but minority-language rights matter for schooling, legal access and Indigenous sovereignty. ASEAN’s working language is English, which facilitates regional diplomacy but also reflects unequal access to global language education.

20.5 Heritage, cultural diplomacy and historical claims

Temples, mosques, churches, monuments, scripts, epics, maritime traditions and foodways create shared heritage across borders. Cultural diplomacy is most credible when it recognizes exchange and local reinterpretation: Angkor is Khmer, Borobudur is Indonesian, Bagan is Myanmar heritage, and India’s civilizational contacts do not make these sites extensions of Indian sovereignty. Heritage policy must also contend with colonial collecting, contested repatriation, mass tourism, religious sensitivities and the destruction of archaeological sites during conflict.

20.6 Religious freedom in practice

Constitutional protection does not ensure freedom in everyday life. Registration requirements for religious organizations, restrictions on conversion, zoning and permits for worship, blasphemy or insult laws, local majoritarian violence and state surveillance may affect communities differently. Comparative legal analysis should distinguish official constitutional guarantees, statutory limits, court decisions, local enforcement and social violence. Equally, it should recognize that religious institutions can provide welfare, education, dispute resolution and community support where state services are weak.

21. Constitutional orders, legal systems and human rights

21.1 India: constitutional supremacy and federalism

India’s Constitution establishes parliamentary government, fundamental rights, a federal division of powers, judicial review, elections, equality before law and freedom of conscience. The Supreme Court’s constitutional overview emphasizes that the Constitution binds legislative, executive and judicial organs and empowers courts to invalidate unconstitutional action. Yet access to justice varies by income, geography, caste, gender and legal literacy; court backlogs and pretrial detention weaken effective remedies. The debate is not simply whether rights are written down, but how reliably people can invoke them. [16]

21.2 ASEAN’s legal diversity

Southeast Asia contains common-law influenced systems, civil-law systems, mixed systems, religious jurisdictions, customary law and socialist legality. Singapore, Malaysia, Brunei and Myanmar retain significant common-law features, though their constitutional arrangements differ; Indonesia and Viet Nam use civil-law traditions and national codification; Thailand combines civil-law influences with its own constitutional and court structures; Laos and Viet Nam operate under one-party socialist systems; Cambodia’s legal framework reflects civil-law and post-conflict influences; the Philippines combines civil-law elements with common-law traditions; and Timor-Leste’s system was shaped by Portuguese law, Indonesian occupation and post-independence reform. These labels are simplifications: each system contains historical layers and evolving practice.

21.3 ASEAN Charter and non-interference

The ASEAN Charter formalizes principles of sovereign equality, non-interference, peaceful dispute settlement and cooperation. These principles help states with different regimes participate in a regional forum and reduce fears of intervention. But the Myanmar crisis exposes their limits: a member can suffer mass violence and humanitarian collapse while collective measures remain constrained by consensus. This is not simply hypocrisy; it is a structural tension between an intergovernmental organization built to protect sovereign autonomy and the need for collective responses to cross-border crises.

21.4 International law at sea

UNCLOS sets the legal framework for territorial seas, exclusive economic zones, continental shelves, navigation and dispute settlement, subject to the Convention’s detailed rules and state practice. The 2016 South China Sea award clarified particular issues within UNCLOS but did not resolve every sovereignty claim. For India and Southeast Asia, maritime law matters to fisheries, energy, shipping, undersea cables, naval operations and environmental protection. Compliance depends on both legal reasoning and political incentives; a sound legal position must be matched by documentation, diplomacy and practical risk management. [30]

21.5 Human rights, speech and political competition

Political-rights assessments and legal reports find substantial variation across the region. India retains competitive elections but faces documented debates about civil liberties, minority protection, investigative powers and internet freedom; several Southeast Asian states restrict opposition, media or civil society, while others maintain more competitive institutions but struggle with corruption, political dynasties and uneven justice. Myanmar’s military coup and conflict are a separate category of state fracture. Rankings such as Freedom House are useful comparative signals, but methodologies should be read and scores should not replace country-specific analysis. [20,21,27]

21.6 Citizenship, refugees and statelessness

Citizenship laws determine access to voting, education, land, health care, lawful work and protection from deportation. India debates citizenship and documentation in the context of the CAA, National Register of Citizens and Assam; Myanmar’s citizenship framework has excluded many Rohingya; stateless communities exist in multiple Southeast Asian settings. Refugee law is fragmented: some countries are not parties to the 1951 Refugee Convention or lack comprehensive asylum systems, leaving refugees dependent on administrative discretion and international assistance. The legal problem is acute when people cross a border without documentation but cannot safely return.

21.7 Labour law and migrant protection

Regional production networks depend on migrant workers, seafarers, domestic workers, construction labour, plantation workers and seasonal agricultural labourers. Labour laws differ on unionization, wage protection, working hours, recruitment fees, employer-tied visas and social insurance. Enforcement often depends on inspection capacity, courts, employer power and migrants’ fear of losing legal status. Bilateral labour agreements, accessible complaints, portable social protection and transparent recruitment can reduce exploitation, but implementation is more important than declarations alone.

21.8 Emergency powers, surveillance and security law

Counterterrorism, public-order, cybercrime, sedition, misinformation and national-security laws affect political competition and privacy. Some measures address real violence and crime; overly broad wording or weak judicial oversight can also chill speech, assembly, journalism and religious practice. Legal safeguards require clear statutory definitions, proportionality, transparent evidence, independent review and accessible remedies. The balance between security and liberty is not unique to Asia, but the balance differs sharply across the region’s constitutional systems.

22. Digital state, cyber governance and the political economy of data

India and Southeast Asia are expanding digital payments, digital identity, e-government, platform commerce, cloud services, AI adoption and data-centre capacity. India has built major public digital infrastructure for identity, payments and service delivery, while Singapore, Indonesia, Malaysia, Thailand, Viet Nam and the Philippines each pursue their own digital-economy strategies. ASEAN DEFA negotiations concluded in May 2026; implementation will test whether interoperable rules can support cross-border commerce while protecting consumers, data, competition and security. [11]

22.1 Opportunity and uneven access

Digital systems can reduce transaction costs, broaden financial access, help small firms reach markets, and improve delivery of public services. They can also exclude people without smartphones, connectivity, literacy, stable identity records or bank access. Rural communities, older people, migrants, women with limited digital autonomy, Indigenous language speakers and people with disabilities can face distinctive barriers. Digital transformation is therefore a governance and inclusion question as much as a technology question.

22.2 Data protection, localization and cross-border flows

States are developing different approaches to privacy, data localization, cybersecurity, cross-border transfer, online platforms and digital competition. Firms need predictable rules; citizens need effective privacy and complaint mechanisms; national-security agencies seek access to data; and governments worry about foreign platform dependence. These goals can conflict. ASEAN interoperability will require not only common standards but credible enforcement, transparent exceptions and safeguards against arbitrary access or surveillance.

22.3 Cybercrime, scams and trafficking

Regional digital growth has been accompanied by cyber fraud, online gambling, romance and investment scams, identity theft and trafficking into scam compounds. Borderland areas with weak rule of law and conflict can become bases for transnational criminal networks. These activities exploit jurisdictional gaps and victims’ reluctance to report. Cooperation needs joint investigations, financial tracing, victim protection, anti-trafficking services and legal channels for data sharing with due process.

22.4 AI, industrial policy and public trust

AI can increase productivity in services, manufacturing, logistics, healthcare, agriculture and education, but benefits depend on computing infrastructure, energy, skilled workers, language resources and competitive firms. AI governance also raises concerns around privacy, copyright, bias, deepfakes, political persuasion and automated decisions. The 2026 ASEAN chairmanship has placed responsible use of emerging technologies among its priorities, while DEFA creates a complementary economic framework. The test is whether these commitments produce enforceable standards and shared capacity rather than aspirational language. [2,11]

23. Climate, energy, food, water and disaster resilience

23.1 The regional climate system

The region faces heat extremes, monsoon variability, cyclones, floods, droughts, landslides, sea-level rise, glacier and snow changes, coral damage, forest loss and peatland fires. Risks differ between the Himalayan headwaters, Indo-Gangetic plain, Bay of Bengal delta, Mekong basin, Mekong and Irrawaddy deltas, tropical islands and urban coasts. Climate impacts are transmitted through crop yields, electricity demand, water storage, tourism, fishing, insurance, public health and migration. Climate risk is a security and economic issue as much as an environmental one.

23.2 Water and transboundary basins

The Ganges-Brahmaputra-Meghna, Indus, Mekong and other river systems connect upstream choices to downstream livelihoods. Dams can generate power, support irrigation and moderate some flood risks, but can also alter sediment, fish migration, seasonal flows and local rights. Water governance is especially difficult when data are limited, trust is low and hydrological change interacts with climate change. Agreements must address data sharing, emergency notification, environmental flows, affected communities and dispute mechanisms rather than only aggregate water volumes.

23.3 Energy security and transition

India depends heavily on imported oil and gas while expanding solar, wind, hydro, nuclear and domestic manufacturing. Southeast Asia includes major energy exporters and importers: Brunei, Indonesia and Malaysia produce hydrocarbons; Thailand and Viet Nam rely on mixed systems; Singapore imports fuels and specializes in refining and trading; Laos exports hydropower; and many states are increasing renewables. Higher energy prices are an external vulnerability that affects inflation, fiscal subsidies, transport and industrial competitiveness. ADB’s September 2026 outlook identifies persistent energy-price volatility as a regional downside risk. [3]

23.4 Food security and rural resilience

Rural incomes, farm size, land tenure, irrigation, fertilizer prices, storage, transport and public procurement determine how climate shocks affect households. Export restrictions can protect national supply but shift scarcity to neighbours. Rice, wheat, palm oil, fish, meat and other commodities have different trade patterns and policy sensitivities. Climate-adaptive agriculture needs research, extension, water management, resilient seeds, storage and income diversification; it also needs to avoid concentrating benefits among large firms while smallholders shoulder transition costs.

23.5 Haze, forests and cross-border pollution

The October 2026 haze crisis in Indonesia illustrates how local land clearing and peat drainage can create regional costs in neighbouring states. AP reported more than 333,470 acute respiratory illness cases across seven Indonesian provinces since mid-August and described protests demanding stronger action; Singapore was pursuing legal action against seven Indonesian companies it blamed for the fires. Weather conditions and an intensifying El Nino aggravated the fires, but land-use decisions, enforcement, corporate responsibility and regional diplomacy remain policy levers. It is a current example of the limits of national sovereignty when environmental damage travels across borders. [10]

23.6 Disaster risk and public trust

Earthquakes, tsunamis, cyclones, floods and volcanic eruptions require regional early warning, emergency logistics, insurance, resilient infrastructure and trusted public communication. ASEAN and India have experience in disaster response, but capacity differs. Disaster policy must protect vulnerable groups, displaced people, disabled people, migrant workers and remote communities. Transparent relief distribution and accountable reconstruction help prevent disasters from deepening existing inequality or creating political grievances.

PART V-FUTURES AND SYNTHESIS 24. Strategic scenarios for 2027-2035

The following scenarios are analytical tools rather than predictions. They identify conditions that may push India and Southeast Asia toward different forms of cooperation or fragmentation. All assume that domestic politics, external economic shocks and regional crises remain important sources of uncertainty.

Scenario A: Practical integration without a security bloc

In this scenario, ASEAN and India deepen trade facilitation, digital connectivity, maritime domain awareness, disaster response, renewable energy, skills and supply-chain cooperation while avoiding a formal anti-China alignment. DEFA implementation improves digital interoperability, AITIGA reform lowers some frictions, and cross-border infrastructure becomes more reliable. Myanmar remains difficult but regional humanitarian cooperation improves. This is the most institutionally incremental path: it requires neither strategic unity nor perfect political alignment, but it does require predictable implementation and sustained trust.

Scenario B: Competitive fragmentation

In this scenario, tariff conflict, sanctions, export controls, maritime incidents, cyberattacks and crisis diplomacy divide supply chains and weaken ASEAN consensus. States face pressure to choose technology and security partners, while domestic polarization makes regional commitments harder to sustain. Investment may still flow, but duplication, uncertainty and restrictions raise costs. Myanmar, South China Sea confrontation or a new India-China border crisis could accelerate fragmentation.

Scenario C: Climate and social stress outrun governance

In this scenario, severe heat, haze, flood, drought, food price spikes and urban disruption interact with debt, inequality and migration. Governments divert public funds to emergency subsidies, while local communities lose livelihoods. Environmental disputes damage regional trust; public discontent spreads through digital channels. This scenario is not inevitable, but current climate and environmental vulnerabilities show why resilience should be treated as core economic infrastructure rather than a secondary policy area.

Scenario D: Nationalist consolidation and narrower civic space

In this scenario, political leaders prioritize centralized control, religious or national identity, security law and managed media environments. In some states, elected governments retain authority while civil liberties weaken; in others, one-party or military rule deepens. Such systems may be able to build infrastructure rapidly but can suppress information, reduce accountability and make policy errors harder to correct. External strategic partnerships may continue even as domestic civic space narrows.

Indicators to monitor

A grounded policy agenda

A practical agenda would prioritize reliable cross-border infrastructure, customs digitization, logistics standards, maritime safety, energy diversification, resilient agriculture, climate adaptation, migrant protection, skills and public-health cooperation. For India, the priority is to align Act East rhetoric with reliable project completion and a competitive manufacturing base. For ASEAN, the priority is to preserve regional agency without allowing consensus to become paralysis. For all parties, the priority is to keep economic integration useful to households and small firms, not only to strategic elites or large corporations.

25. Conclusions: a connected but non-unified region

India and Southeast Asia are bound by geography, history, maritime exchange, migration, religious traditions, trade and contemporary strategic interdependence. The Bay of Bengal and the Strait of Malacca are not peripheral waterways; they are the connective tissue of a major economic region. The Himalaya, Mekong basin, archipelagos, monsoon systems and tropical coasts shape livelihoods and state capacity, while ports, roads, digital networks and legal rules determine whether geography becomes an advantage.

The histories of India and Southeast Asia show both transmission and local agency. Precolonial trade moved language, religion and political concepts, but Southeast Asian societies transformed them into their own institutions and cultural forms. Colonial rule redrew borders, property, law, labour, trade and state structures; national movements then produced varied paths to independence. The Cold War shaped alliances and violence, while post-1990 liberalization and China’s rise created deeper economic ties and new strategic risks.

Contemporary India is a large democratic federal state with significant economic momentum, but development gains are uneven and its security relationships with China and Pakistan remain difficult. Southeast Asia is an 11-member regional organization with diverse national political systems and economic trajectories. ASEAN’s consensus and non-interference norms preserve dialogue across difference but constrain collective action on crises such as Myanmar. The 2026 conclusion of DEFA negotiations demonstrates that regional institution-building can still advance even amid geopolitical rivalry.

The social, religious and legal dimensions cannot be separated from geopolitics. Caste, ethnicity, migration, gender, citizenship, religion, labour and civil liberties affect trust in institutions and the distribution of growth. India and Southeast Asian countries differ in their constitutions and legal traditions, but all confront questions about balancing security with rights, economic opportunity with inequality, and national identity with pluralism. Political stability is more durable when institutions provide lawful avenues for criticism, redress and participation.

The coming decade will test whether regional states can build cooperation around public goods while retaining strategic autonomy. Trade and supply chains can make conflict costly but do not eliminate nationalist rivalry. Maritime law can clarify rights but needs political willingness and practical safeguards. Climate risks create common interests but also intensify competition over water, energy and land. The most plausible path is neither a unified bloc nor inevitable fragmentation, but differentiated cooperation: pragmatic integration where incentives align, crisis management where disputes persist, and transparent legal processes where rights and sovereignty are contested.

The central finding of this report is therefore simple but consequential: India and Southeast Asia should be studied as an interconnected system whose unity lies in geography and history, not in identical political choices. Their future will depend on how governments and societies manage interdependence-through credible institutions, inclusive growth, resilient infrastructure, respect for international law and the political imagination to cooperate without erasing difference.

Appendix C. Source guide and research method

How to read current data

The report uses a clearly defined information cut-off of 25 October 2026. Current reporting may be updated after this date; the report is a snapshot, not a live intelligence feed. Forecasts from ADB and the World Bank reflect their publication dates and assumptions. Statistics should be compared only when the time period, currency, coverage and definition match. Where a figure is drawn from news reporting during a developing crisis, the report identifies the date and avoids treating it as a final annual total.

How to read conflicting claims

Territorial and maritime disputes should be presented with attribution. For example, the 2016 South China Sea award clarified rights under UNCLOS but did not decide sovereignty over land features; China rejects the award while the Philippines maintains its legal position. Similarly, India and Pakistan dispute accounts of particular border incidents, and India-China border claims remain unresolved. A research report should distinguish an established institutional fact, a party’s claim, a court or tribunal’s finding, and an analyst’s interpretation.

Source types and limitations

• Official sources: excellent for laws, treaties, membership, government policy and official statistics; they may present events through a state’s own legal or political position.
• International organizations: useful for comparable economic and humanitarian data; their regional aggregates may differ by geographic and fiscal definitions.
• Academic books and journals: strongest for historical depth and causal interpretation; publication dates matter in a rapidly changing current-affairs context.
• News organizations: useful for dated events and statements; individual reports should be corroborated for disputed or high-stakes claims.
• Think tanks and rights monitors: useful for focused analysis, but their frameworks and methods should be considered; do not turn a score into a complete judgement of a society.
