India-China Border Dispute
Three Sectors
The India-China boundary has never been formally delimited and demarcated along its approximately 3,488 km (the Line of Actual Control, or LAC). The dispute is organised around three geographic sectors with distinct histories and legal frameworks.
- Western Sector (Aksai Chin): ~38,000 sq km, administered by China since 1962 war; India claims it; China built the G219 highway linking Tibet to Xinjiang through this area.
- Middle Sector (Himachal Pradesh/Uttarakhand): Least contentious; approximate alignment broadly accepted by both sides.
- Eastern Sector (Arunachal Pradesh): ~90,000 sq km, administered by India; China calls it "South Tibet"; the McMahon Line is the de facto boundary; China specifically claims Tawang.
- The 1962 Sino-Indian War: India's defeat led to China occupying Aksai Chin; ceasefire established the LAC as the de facto boundary.
- The 2020 Galwan Valley clash (June 2020) was the first lethal confrontation since 1975; 20 Indian soldiers killed.
- Disengagement process: India and China reached a patrolling agreement in October 2024, with patrolling resumed at Depsang and Demchok friction points — a significant step toward normalisation.
