India & China

Story hook

It is 15-16 June 2020. On a knife-edge ridge above the Galwan river in Eastern Ladakh, at an altitude of 4,300 metres, Colonel B. Santosh Babu of the 16 Bihar Regiment walks into talks with a Chinese contingent of the People's Liberation Army (PLA). The conversation degenerates. Spiked rods, iron bars wrapped in barbed wire, and rocks come out. By dawn 20 Indian soldiers are dead, including Col Babu. China admits 4 fatalities months later (Indian assessment is higher). This is the first combat death on the India-China border since 1975 — when an Indian patrol was ambushed at Tulung La, Arunachal Pradesh.

Four years later, on 23 October 2024, on the eve of the BRICS Kazan Summit, the two governments announce a patrolling agreement on Demchok and Depsang — the last two friction points. Modi and Xi Jinping hold their first formal bilateral since 2019 the next day. The "Wuhan-Mamallapuram" informal-summit playbook of 2018-19 may yet return, but on tougher Indian terms: trust must be earned, not assumed.

Between these two snapshots lies the entire grammar of India-China relations — a 3,488-km Line of Actual Control (LAC), a $118 billion annual trade deficit (FY2024), a $100+ billion two-way trade, contested rivers (Brahmaputra), competing visions for the Indo-Pacific, parallel memberships in BRICS, SCO, G20, and a fundamental disagreement on boundary, Tibet, terrorism (Masood Azhar), CPEC and the NSG.

Why this matters for UPSC

India-China is the primary strategic challenge of the 21st century for India. Every Mains GS-II cycle carries a question on it — boundary, trade asymmetry, strategic posture, or Indo-Pacific. Prelims has tested LAC sectors, Doklam location, the BRICS member-states, and SCO. Interviews routinely probe the "Wuhan Spirit" vs "Galwan Reality" dilemma and the trade-deficit paradox.
