Sri Lanka sits only 30 km south of India at the nearest point — closer to Tamil Nadu than Delhi is to Agra. The two countries share 2,500 years of civilisational contact, a Free Trade Agreement since 2000, and an unresolved Tamil question that runs through Indian domestic politics. India's response to Sri Lanka's 2022 sovereign default — nearly USD 4 billion in credit lines, fuel, fertiliser and food — rebuilt strategic trust that had frayed during the Rajapaksa years. For UPSC GS II, Sri Lanka tests SAGAR, the 13th Amendment politics, Hambantota debt diplomacy, and the fishermen-Katchatheevu dispute.
Strategic significance
Maritime
- Astride global shipping lanes carrying Asian-European trade.
- Indispensable for India's SAGAR doctrine and net security provider ambition.

Trade and investment
- India is Sri Lanka's largest trade partner globally.
- Sri Lanka provides investment opportunities for Indian infrastructure: Colombo West Container Terminal (Adani-John Keells-SLPA) is an example.
- India-Sri Lanka FTA (2000) — first FTA India signed with a neighbour.
- Negotiations on Economic and Technology Cooperation Agreement (ETCA) continue intermittently.
Connectivity
Transshipment through Colombo and Hambantota ports handles significant Indian cargo because India has not yet fully developed a deep transshipment port.
Maritime security cooperation
- Dornier maritime surveillance aircraft provided to Sri Lanka.
- Maritime Rescue Coordination Centre (MRCC) — inaugurated with installations across Sri Lanka's coastline.
- Joint exercises SLINEX.
Energy
- High-capacity power grid interconnection planned for bidirectional electricity trade; BBIN-type extension.
- Undersea transmission line — USD 1.2 billion project — linking Sri Lanka's grid with India for energy security.
- Trincomalee oil tank farm redevelopment — joint venture between Indian Oil Corporation and Ceylon Petroleum Corporation.
Digital
- UPI-based digital payments operationalised in 2024.
- Digital Public Infrastructure (DPI) cooperation under India Stack.
Tourism
- Indian tourists are the largest source for Sri Lanka.
- Buddhist circuit cooperation; medical tourism.
Challenges
Ethnic issues
- Sinhala-Tamil conflict (1983-2009).
- Lack of full devolution under the 13th Amendment (1987) — legacy of the Indo-Sri Lanka Accord and the IPKF.
- India has pressed for meaningful implementation of the 13th Amendment.
UNHRC
India's vote against Sri Lanka at UNHRC (2012, 2013) on accountability for war crimes; abstained in 2021, 2022, 2024.
Fishermen issue
- Indian fishermen from Tamil Nadu and Sri Lankan Navy clashes.
- Bottom trawling by Indian vessels in Sri Lankan waters — an ecological and livelihood issue.
- Katchatheevu island dispute — ceded to Sri Lanka in 1974 by Indira Gandhi; Tamil Nadu politics continues to raise the question.
Trust deficit
- Scrapping of Colombo East Container Terminal (2021) by the Rajapaksa government after initial MoU with India-Japan consortium — a low point.
- China factor: Colombo Port City, Hambantota 99-year lease to China (2017), Belt and Road Initiative membership.
Sri Lanka's 2022 crisis and India's response
The crisis

Katchatheevu: the uninhabited island that won't go away
Katchatheevu is a 285-acre uninhabited island in the Palk Strait, ceded by India to Sri Lanka under the 1974 Maritime Boundary Agreement. The Sri Lankan Navy enforces fishing rights, leading to repeated arrests of Tamil Nadu fishermen. Tamil Nadu's political parties demand its retrieval; the Supreme Court was moved in 2008 on the issue. Diplomatically, the island is closed — no government has sought to reopen — but the fishermen's livelihoods remain a live issue.
Tamil question and the 13th Amendment
The 13th Amendment to the Sri Lankan Constitution (1987) — passed as part of the India-Sri Lanka Accord — created provincial councils and devolved land, law-and-order, education, and health powers. Full implementation has been patchy. India continues to press the Sri Lankan government for:
- Full devolution of promised powers.
- Provincial Council elections (pending since 2018).
- Meaningful political solution to the Tamil question.
Dissanayake's NPP government (elected September 2024), despite its JVP roots opposing the Accord historically, has signalled openness to implementation.
Connectivity push in detail
- Palk Strait ferry — Nagapattinam-Kankesanthurai ferry operational since October 2023.
- Rameswaram-Talaimannar ferry — in planning.
- Colombo West Container Terminal — Adani-John Keells-SLPA; operational 2025.
- Sampur LNG terminal and power plant.
- Undersea power cable — USD 1.2 billion project.
- Adani renewable projects — 484 MW in Mannar and Pooneryn; clearances 2024.
