India‑China Border
The India‑China border, spanning roughly 3,488 km across the Himalayas, the Karakoram, and the Tibetan Plateau, is one of the world’s most contested frontiers. It comprises three distinct sectors – the Western (Aksai Chin‑Ladakh), Middle (Himachal‑Uttarakhand‑Sikkim) and Eastern (Arunachal Pradesh‑Tibet) – each with its own historical claims, treaties, and flash‑points. For UPSC aspirants, this topic is pivotal because it intertwines geopolitics, security, foreign policy, constitutional law, and development challenges. Understanding the evolution of the boundary, the legal instruments that frame India’s stance, and the contemporary dynamics of border management equips candidates to answer questions on India’s external affairs, defence preparedness, and the interplay between national sovereignty and regional stability.
Constitutional/Legal foundation – India’s claim over the entire Line of Actual Control (LAC) is anchored in Article 370 (now abrogated) and Article 2 of the Constitution, which empower Parliament to admit new territories, and is reinforced by historic treaties such as the Treaty of Friendship (1954), the Panchsheel Agreement (1954), and the 1993 Agreement on the Maintenance of Peace and Tranquility along the LAC. The Supreme Court’s jurisprudence on “integral part of the territory” (e.g., Kashmir cases) also informs the legal discourse on border disputes.
