Basic Structure

India-Bangladesh relations represent one of South Asia's most significant bilateral partnerships, rooted in the 1971 Liberation War when India played a decisive role in Bangladesh's independence. The relationship spans a 4,096-kilometer border, making it one of the world's longest international frontiers.

Key foundations include the Treaty of Friendship, Cooperation and Peace (1972) and over 54 bilateral agreements covering trade, connectivity, water sharing, and security. Economically, bilateral trade exceeds $18 billion annually, with India being Bangladesh's second-largest global trading partner.

Major cooperation areas include railway and road connectivity, power transmission (1,100+ MW electricity supply), and development assistance through $8 billion in Lines of Credit. Water diplomacy remains crucial, with the Ganges Water Sharing Treaty (1996) as a success story, while the Teesta agreement remains pending.

The historic Land Boundary Agreement (2015) resolved the complex enclave issue, exchanging 162 enclaves and affecting 50,000+ people. Security cooperation encompasses border management, counter-terrorism, and maritime security in the Bay of Bengal.

Cultural ties through shared Bengali heritage, educational exchanges, and people-to-people connections provide relationship resilience. Current challenges include trade imbalances, water disputes, border management issues, and managing China's growing influence in Bangladesh.

The relationship exemplifies how historical bonds, geographical realities, and strategic interests can create comprehensive partnerships despite occasional political differences.
