India–China Relations
Historical Framework and the Border Dispute
India and China share a 3,488 km disputed boundary, divided into three sectors: the western sector (Ladakh — where China controls Aksai Chin), the middle sector (Himachal Pradesh/Uttarakhand), and the eastern sector (Arunachal Pradesh — which China claims as "South Tibet"). The Line of Actual Control (LAC) — not a formally demarcated boundary — serves as the de facto border. The term "LAC" was first used by Chinese Premier Zhou Enlai in a 1959 letter to Indian Prime Minister Jawaharlal Nehru, and the current LAC took shape after the 1962 Sino-Indian War. The two countries have no settled boundary and maintain the Special Representatives Mechanism (SRM), established in 2003, for border negotiations.

- SRM (Special Representatives Mechanism): established 2003 under "Declaration on Principles for Relations and Comprehensive Cooperation"
- 2020 Galwan Valley clash: 20 Indian soldiers killed; triggered four-year disengagement process
- October 2024 patrolling agreement: India and China reached an agreement on LAC patrolling resumption, resolving the 2020 standoff
- China's "salami-slicing" strategy: incremental territorial occupation along disputed borders
