India-Sri Lanka Maritime Friction: Fishermen Livelihoods and the Katchatheevu Dispute

From a policy perspective, the issue presents a significant challenge to India’s 'Neighborhood First' policy. While New Delhi seeks to maintain strategic ties with Colombo, especially in the face of regional geopolitical competition, the humanitarian and economic concerns of the Tamil Nadu fishing community demand proactive diplomatic intervention. The situation also highlights the need for sustainable fishing practices, as the depletion of resources on the Indian side of the International Maritime Boundary Line (IMBL) often drives fishers to cross into Sri Lankan waters. For UPSC aspirants, this development is a classic case study of how domestic socio-economic issues can influence foreign policy. It involves understanding the legalities of the United Nations Convention on the Law of the Sea (UNCLOS), the historical context of Indo-Lanka treaties, and the role of sub-national actors in international relations. UPSC Relevance: This topic is highly relevant for GS Paper II (India and its neighborhood relations) and GS Paper III (Security challenges in border areas). It provides a practical example of maritime boundary disputes, the impact of historical treaties on modern livelihoods, and the diplomatic challenges of balancing bilateral ties with domestic welfare.
