BIMSTEC

1. Origins, membership and institutional structure

BIMSTEC emerged from the recognition that the Bay of Bengal could connect South Asia with Southeast Asia through trade, transport and functional cooperation. The Bangkok Declaration of 6 June 1997 created BIST-EC with Bangladesh, India, Sri Lanka and Thailand. Myanmar joined in December 1997, followed by Bhutan and Nepal in 2004. With seven members, the grouping adopted its present name. Nepal and Bhutan are landlocked, but access to Bay of Bengal ports gives them a direct stake in regional connectivity.

BIMSTEC is an intergovernmental organisation based on sovereign equality, territorial integrity, political independence, non-interference, peaceful coexistence and mutual benefit. Decisions are taken by consensus. Its institutional structure includes summits of heads of state or government, ministerial meetings, senior officials’ meetings and sector-specific mechanisms. The permanent Secretariat, inaugurated in Dhaka in 2014, coordinates activities, although delivery still depends substantially on national governments.

The Charter, adopted at the fifth summit hosted virtually by Sri Lanka on 30 March 2022, entered into force on 20 May 2024. It established a clearer legal and institutional framework and conferred legal personality on BIMSTEC. The sixth summit in Bangkok in April 2025 adopted the Bangkok Vision 2030 and saw the signing of the Agreement on Maritime Transport Cooperation. These developments mark institutional consolidation, but their practical value depends on sustained implementation.

• The chairmanship rotates among members according to the alphabetical order of their English names.
• The Charter envisages regular summit meetings; historically, long intervals between summits weakened political direction.
• Consensus protects smaller states’ autonomy but can slow decisions where national priorities diverge.

2. Agenda and areas of cooperation

In 2022, BIMSTEC rationalised its previously dispersed agenda into seven sectors, each assigned to a lead country. Bangladesh leads trade, investment and development; Bhutan, environment and climate change; India, security; Myanmar, agriculture and food security; Nepal, people-to-people contact; Sri Lanka, science, technology and innovation; and Thailand, connectivity. The arrangement seeks clearer ownership without making the lead country solely responsible for implementation.

Connectivity is central because weak transport links and cumbersome border procedures prevent geographical proximity from becoming economic integration. The BIMSTEC Master Plan for Transport Connectivity, adopted in 2022 with Asian Development Bank support, covers roads, railways, ports, inland waterways, aviation and trade facilitation. Physical infrastructure must be complemented by customs coordination, transit arrangements, interoperable documentation and predictable border management.

Economic integration remains incomplete. A Framework Agreement on the BIMSTEC Free Trade Area was signed in 2004, but a comprehensive FTA has not become operational. Sensitive products, rules of origin, services, investment and customs procedures involve difficult negotiations. The 2018 memorandum on establishing a BIMSTEC Grid Interconnection provides a framework for electricity cooperation, potentially linking Himalayan hydropower with regional demand.

Security cooperation includes counterterrorism and transnational crime, alongside energy and disaster management within India’s sectoral responsibility. The Convention on Cooperation in Combating International Terrorism, Transnational Organised Crime and Illicit Drug Trafficking entered into force in 2021. Climate adaptation, public health, agricultural resilience and scientific collaboration widen BIMSTEC’s relevance beyond conventional diplomacy.

• A cooperation framework or signed agreement should not be confused with a fully functioning regional market or electricity grid.
• Maritime cooperation requires attention to shipping services, port efficiency, safety and the interests of coastal communities.

3. Strategic importance for India

BIMSTEC brings together three strands of Indian foreign policy: Neighbourhood First, Act East and cooperation in the Indian Ocean. It enables India to engage its eastern neighbours while connecting with Myanmar and Thailand. India invited BIMSTEC leaders to its prime ministerial swearing-in ceremony in 2019, signalling the grouping’s political importance. It also offers an avenue for regional cooperation amid the prolonged stagnation of SAARC.

For India’s Northeast, improved links through Bangladesh and Myanmar can reduce isolation and expand access to ports, markets and production networks. The India–Myanmar–Thailand Trilateral Highway and the Kaladan Multi-Modal Transit Transport Project illustrate the broader connectivity agenda. They are not automatically BIMSTEC-owned projects; rather, they can support the regional objectives that BIMSTEC promotes. Security conditions and unfinished infrastructure have constrained their potential.

The Bay of Bengal is important for commercial shipping, energy transport, fisheries and maritime security. Cooperation can improve responses to cyclones, trafficking, terrorism and environmental degradation. BIMSTEC also gives India opportunities to provide public goods through training, disaster assistance, technology and infrastructure finance. It should not, however, be portrayed simply as an anti-China coalition: members pursue varied external partnerships and value strategic autonomy.

• BIMSTEC can complement SAARC and ASEAN but cannot replace their different memberships, mandates and institutional roles.
• India’s credibility depends on timely delivery, consultation and equitable benefits rather than diplomatic announcements alone.

4. Constraints and critical assessment

The principal weakness is the gap between commitments and delivery. BIMSTEC has historically suffered from irregular summits, a broad agenda, limited Secretariat capacity and insufficient implementation resources. Member countries differ considerably in economic size, administrative capacity and development priorities. Without realistic project selection and sustained financing, regional plans can become lists of aspirations rather than instruments of integration.

Political tensions do not disappear merely because Pakistan is absent from the grouping. Myanmar’s conflict following the February 2021 military takeover has disrupted cross-border connectivity and created diplomatic difficulties. The Rohingya displacement crisis has strained Bangladesh–Myanmar relations. Political changes elsewhere can also affect project continuity, transit arrangements and public acceptance of cooperation with neighbouring countries.

Trade faces both infrastructure and regulatory barriers. Difficult border crossings, inconsistent standards, weak logistics and restrictions on movement limit participation by smaller firms. Large infrastructure projects also raise concerns about debt, displacement, biodiversity and climate vulnerability. Ports and transport corridors need resilient design because the Bay of Bengal is highly exposed to cyclones, storm surges and coastal flooding.

• Absence of India–Pakistan rivalry reduces one obstacle to cooperation; it does not guarantee regional cohesion.
• Economic asymmetry can generate concerns about unequal gains unless benefits are visible across member countries.
• Overlapping bilateral, subregional and regional initiatives require coordination rather than duplicated institutions.

5. Way forward and examination perspective

BIMSTEC should prioritise a limited number of achievable regional public goods: smoother border procedures, reliable shipping links, disaster early warning, electricity cooperation and professional exchanges. Strengthening the Secretariat with technical expertise, predictable funding and public progress reporting would improve accountability. Each priority project should have a responsible agency, financing plan, timetable and measurable outcomes.

Trade facilitation should proceed alongside negotiations on the wider FTA. Electronic documentation, standards cooperation and improved border infrastructure can produce benefits before a comprehensive trade agreement is concluded. Regional connectivity must include environmental safeguards, community consultation and opportunities for smaller economies and local enterprises. Existing electricity arrangements can inform wider cooperation without being misrepresented as a completed BIMSTEC grid.

For India, the appropriate approach is consultative leadership: delivering commitments, accommodating smaller neighbours’ concerns and avoiding excessive securitisation. In a Mains answer, assess BIMSTEC as a bridge between regions and a mechanism for practical cooperation, not merely as an alternative to SAARC. Its success should be judged by reduced transport costs, greater resilience and tangible improvements in citizens’ welfare.

• Analytical conclusion: BIMSTEC’s geographical promise requires institutional capacity and political trust to become meaningful regional integration.
