India and Bangladesh

Why the topic matters for UPSC

India‑Bangladesh relations are a cornerstone of South‑Asian geopolitics. The two neighbours share a 4,096 km porous border, a common riverine ecosystem, intertwined economies, and deep cultural‑linguistic ties. For a civil‑service aspirant, understanding this bilateral partnership is essential for answering questions on foreign policy, border management, water‑sharing, trade, security, migration, regional groupings (SAARC, BIMSTEC, IORA), and India’s “Neighbourhood First” doctrine. Moreover, the historical legacy of the 1971 Liberation War continues to shape diplomatic narratives, defence cooperation, and people‑to‑people contact—areas that frequently surface in both Pre‑lims fact‑based questions and Mains essay/GS‑II/III answer‑writing.

Constitutional / legal foundation

  • India‑Bangladesh Friendship Treaty (1972) and the Indus‑Water‑Treaty‑style agreements on the Ganges (1975), Teesta (1996) and other rivers provide the legal scaffolding for water‑sharing and border management.
  • Both countries are signatories to SAARC (1985), BIMSTEC (1997), IORA (2011) and the Commonwealth, which institutionalise multilateral cooperation.
