 Significance of BIMSTEC for India

BIMSTEC holds immense strategic and economic significance for India, allowing it to pursue several core foreign policy objectives:

  • Neighbourhood First Policy: It reinforces India's commitment to its immediate neighbours in the Bay of Bengal region, supporting stability and growth in the periphery.

  • Act East Policy: BIMSTEC is a critical component of the Act East Policy, acting as the primary link connecting India's Northeast states with Southeast Asian markets via Bangladesh and Myanmar.

  • Economic Development of Northeast States: By strengthening regional connectivity, particularly through projects like the India-Myanmar-Thailand Trilateral Highway, it boosts the economic development of India's landlocked Northeast region.

  • Alternative to SAARC: Given the structural and political hurdles within the South Asian Association for Regional Cooperation (SAARC), BIMSTEC offers India a viable and stable platform for regional cooperation, especially with its eastern neighbours.

  • Security and Counter-Influence: It is a vital platform for enhancing maritime security cooperation and countering non-traditional threats in the Bay of Bengal. It also provides a mechanism to balance the increasing strategic influence of external powers in the region.

Challenges for BIMSTEC

Despite its potential, BIMSTEC faces several challenges that hinder its progress:

  • Slow Progress: The organization has historically suffered from a slow pace of progress, with key initiatives like the BIMSTEC Free Trade Area (FTA) Framework Agreement, signed in 2004, still under negotiation.

  • Wide Focus Area: The initial broad focus across many sectors (14 before rationalization) led to a dilution of efforts. While rationalization of the seven core sectors is a positive step, effective implementation remains key.

  • Lack of Resources: The Secretariat requires greater capacity, both in terms of manpower and dedicated funding, to effectively manage and implement regional projects.

  • Bilateral Issues: Bilateral conflicts, such as the Rohingya refugee crisis involving Myanmar and Bangladesh, can sometimes cast a shadow over the regional cooperative spirit.

  • Inadequate Connectivity: A lack of robust physical and digital connectivity infrastructure remains a major constraint on boosting intra-regional trade, which currently stands at a low percentage.
