BIMSTEC

Geography glossary

Also called: Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation, BIST-EC · Topic: India and her Neighbours · NCERT: Beyond NCERT

Meaning

BIMSTEC (Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation) is a regional group of seven countries around the Bay of Bengal: Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka and Thailand. It was founded on 6 June 1997 through the Bangkok Declaration. Its Permanent Secretariat is in Dhaka.

It matters because it joins South Asia to South-East Asia. India's Neighbourhood First and Act East policies meet in this group. With SAARC stuck (no summit since 2014), BIMSTEC has become India's main regional platform in its eastern neighbourhood.

Explanation

How it grew: from four members to seven

  • 1997, BIST-EC: the group began with 4 members, Bangladesh, India, Sri Lanka and Thailand. The name came from their first letters.
  • December 1997: Myanmar joined. The name became BIMST-EC.
  • 2004: Nepal and Bhutan joined, and the group took the name BIMSTEC.
  • Result: 5 South Asian members (Bangladesh, Bhutan, India, Nepal, Sri Lanka) and 2 South-East Asian members (Myanmar, Thailand).

How it became a formal organisation

Each step took years:

  • 2014: a Memorandum of Association for the Secretariat was signed at Nay Pyi Taw. The Permanent Secretariat in Dhaka has worked since September 2014.
  • 2015: a Headquarters Agreement was signed with Bangladesh at Dhaka.
  • 30 March 2022: the BIMSTEC Charter (its founding rulebook) was adopted at the 5th Summit in Colombo, which was held online.
  • 20 May 2024: the Charter came into force, according to the MEA. Under the Charter it starts working 30 days after the 7th member deposits its ratification (formal approval at home). So every member has to agree first.
  • The pace: 17 years from founding to a working Secretariat, and 27 years to a Charter in force.

How it works: sectors and pillars

  • Multi-sectoral: the group covers many fields of cooperation, not just one. Its full name stresses technical and economic cooperation, not defence.
  • 7 pillars: the 2022 Charter grouped the priority areas into 7 pillars. Each pillar is led by one member state.
  • India leads discussions on maritime security, cyber security and space.
  • Consensus: decisions need every member to agree, so the slowest member sets the pace.
  • 6th Summit, Bangkok, 4 April 2025:
  • It signed the BIMSTEC Maritime Transport Agreement. The agreement gives each member's ships, crew and cargo the same treatment as local ones, recognises each other's certificates, sets up a Joint Shipping Coordination Committee and creates a way to settle disputes.
  • It adopted the Bangkok Vision 2030.

Why the Bay of Bengal makes it work

  • Shared sea: most members either touch the Bay of Bengal or depend on it for trade. India, Bangladesh, Myanmar and Sri Lanka border it. Thailand faces it across the Andaman Sea.
  • Landlocked members: Nepal and Bhutan have no coast. Through BIMSTEC they get a link to the sea and to South-East Asia.
  • India as the link: India shares a land border with 4 members (Bangladesh, Nepal, Myanmar, Bhutan) and a maritime boundary with Sri Lanka, Thailand, Myanmar and Bangladesh.

Where it occurs

  • Region: the countries around the Bay of Bengal, from the Himalaya (Nepal, Bhutan) down to the Indian Ocean islands (Sri Lanka) and east to the Malay peninsula (Thailand).
  • Key places:
  • Bangkok (Thailand): where the 1997 Declaration was signed and the 6th Summit was held (2025).
  • Dhaka (Bangladesh): the Permanent Secretariat.
  • Colombo (Sri Lanka): where the Charter was adopted (2022).

  • Nay Pyi Taw (Myanmar): where the Secretariat Memorandum of Association was signed (2014).

  • India's land borders with BIMSTEC members (MHA):

  • Bangladesh 4,096.7 km (India's longest border), touching West Bengal, Assam, Meghalaya, Tripura and Mizoram.
  • Nepal 1,751 km, touching Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim.
  • Myanmar 1,643 km, touching Arunachal Pradesh, Nagaland, Manipur and Mizoram.

  • Bhutan 699 km, touching Sikkim, West Bengal, Assam and Arunachal Pradesh.

  • Connectivity projects that serve the BIMSTEC space:

  • Kaladan project: ships run from Kolkata to Sittwe port in Myanmar, boats go up the Kaladan river to Paletwa, and a road continues to Zorinpui (Mizoram). It bypasses the Siliguri Corridor.

  • India-Myanmar-Thailand Trilateral Highway: about 1,360 km, from Moreh (Manipur) via Mandalay and Bagan to Mae Sot (Thailand).

  • India's eastern edge: the Andaman and Nicobar Islands sit in the Bay of Bengal, on the approach to the Malacca Strait.

Don't confuse with

  • SAARC: founded in 1985 at Dhaka, with its secretariat in Kathmandu and 8 members, including Pakistan, Afghanistan and the Maldives. BIMSTEC's secretariat is in Dhaka, and those three countries are not members.
  • IORA (Indian Ocean Rim Association): also set up in 1997, but it covers countries around the whole Indian Ocean. BIMSTEC covers only the Bay of Bengal region.
  • ASEAN: a South-East Asian group. Only 2 BIMSTEC members, Myanmar and Thailand, belong to ASEAN. BIMSTEC is the bridge between SAARC countries and ASEAN countries.
  • BIST-EC vs BIMSTEC: BIST-EC was the 1997 four-member group. "BIMSTEC" with 7 members dates from 2004, when Nepal and Bhutan joined.

Prelims Hooks

  • BIMSTEC was founded on 6 June 1997 by the Bangkok Declaration, but its Secretariat is in Dhaka, not Bangkok.
  • Members: Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka and Thailand. That is 5 South Asian and 2 South-East Asian countries. Maldives, Pakistan and Afghanistan are not members.
  • Order of joining: Bangladesh, India, Sri Lanka and Thailand (1997) → Myanmar (December 1997) → Nepal and Bhutan (2004).
  • Charter: adopted at Colombo on 30 March 2022, in force from 20 May 2024 (per MEA). Do not mix up the two dates.
  • Its priority areas are grouped into 7 pillars, each led by one member state.
  • Trap: "Only coastal states are BIMSTEC members." FALSE. Nepal and Bhutan are landlocked members.

Mains Points

  • Bridge between South and South-East Asia
  • BIMSTEC links Act East (Myanmar, Thailand) with Neighbourhood First (Bangladesh, Nepal, Bhutan, Sri Lanka).
  • The North-East's only land link to the rest of India is the narrow Siliguri Corridor (about 20-22 km). Routes through Bangladesh, Kaladan (Sittwe) and the Trilateral Highway can give the region other ways out.

  • With SAARC stalled since 2014, BIMSTEC lets India cooperate regionally without Pakistan.

  • The Bay of Bengal as shared space (GS-III)

  • The bay is prone to cyclones, so disaster cooperation comes naturally. BIMSTEC has held disaster management exercises since 2017.
  • The 2025 Maritime Transport Agreement aims to grow sea trade and shipping links among members.

  • Landlocked Nepal and Bhutan gain from sea routes through the region.

  • Limits and the way forward

  • It took 27 years to get a Charter in force, which shows how slow consensus decisions are.
  • Projects run through unstable areas, such as Myanmar's Rakhine State (Sittwe), and many are still incomplete.
  • The way forward: finish connectivity projects on time, give the Dhaka Secretariat more capacity, and turn sector-wise plans into regular working mechanisms.
