India–Sri Lanka Bilateral Relations: Framework, Agreements, and Institutional Architecture

India and Sri Lanka share a deeply interconnected relationship shaped by geography, history, culture, and strategic maritime alignment in the Indian Ocean Region. As Sri Lanka’s closest geographical neighbor, separated only by the narrow Palk Strait, India places the island nation at the core of its “Neighbourhood First” policy and SAGAR (Security and Growth for All in the Region) vision. The institutional framework governing bilateral ties has expanded over decades from early population agreements to sophisticated economic, security, and connectivity partnerships.

Historical Accords and Treaties

Bilateral cooperation is rooted in foundational agreements signed to address demographic status, boundary definitions, and conflict resolution:

• Srima-Shastri Pact (1964): Addressed the legal status of Indian-origin Tamils working in Sri Lankan plantations. Under this accord, Ceylon agreed to grant citizenship to 300,000 individuals, while India agreed to repatriate a specified population.
• Indo-Sri Lanka Maritime Boundary Agreements (1974 & 1976): Settled maritime boundaries in the Palk Strait, Gulf of Mannar, and Bay of Bengal. The 1974 agreement recognized Sri Lanka’s sovereignty over the disputed island of Kachchatheevu.
• Indo-Sri Lanka Accord (1987): Signed by Indian Prime Minister Rajiv Gandhi and Sri Lankan President J. R. Jayewardene to resolve the Sri Lankan civil war. It led to the 13th Amendment to the Sri Lankan Constitution, creating Provincial Councils and devolving powers to Sri Lanka’s northern and eastern provinces.

Economic and Commercial Agreements

Trade and investment frameworks form the backbone of economic engagement, facilitating trade flows across South Asia.

Trade Frameworks

• India–Sri Lanka Free Trade Agreement (ISFTA): Signed in 1998 and operationalized in 2000, ISFTA was India’s first bilateral free trade agreement. It provided duty-free access to thousands of tariff lines, boosting total bilateral trade.
• Economic and Technology Cooperation Agreement (ETCA): A proposed comprehensive expansion of ISFTA designed to include trade in services, technology transfer, and investment protections.
• Local Currency Settlement Arrangement: Both nations established mechanisms enabling cross-border commercial transactions in Indian Rupees (INR) to lessen reliance on foreign currency reserves.
