Why this matters now
India-China is a top GS-2 topic — the boundary dispute, the post-Galwan situation, trade dependence, and the strategic rivalry. Balance the cooperation and competition dimensions.
The boundary dispute
The core issue is the un-demarcated boundary — the Line of Actual Control (LAC) — with disputes in the western sector (Aksai Chin, held by China) and the eastern sector (Arunachal Pradesh, claimed by China). The legacy of the 1962 war and repeated standoffs keep it tense.
Galwan and after
The 2020 Galwan Valley clash (eastern Ladakh) — the first deadly border incident in decades — severely strained ties, leading to military build-ups, multiple rounds of disengagement talks, and a recognition that “peace and tranquillity on the border” is the basis for normal relations.
Economic ties
China is one of India’s largest trade partners, but trade is heavily skewed — India runs a large trade deficit and depends on Chinese imports (electronics, APIs, machinery). Post-Galwan, India tightened FDI scrutiny and restricted some Chinese apps, pushing self-reliance (Atmanirbhar Bharat, PLI).
Strategic competition
Beyond the border, India and China compete across Asia: China’s Belt and Road Initiative (BRI) and the China-Pakistan Economic Corridor (CPEC) (which India opposes), influence in India’s neighbourhood (the “String of Pearls”), and rivalry in multilateral forums — even as they cooperate in BRICS and the SCO.
UPSC angle
Cover the boundary (LAC, Aksai Chin/Arunachal, 1962), the post-Galwan freeze, the lopsided trade dependence, and strategic competition (BRI/CPEC, neighbourhood) alongside BRICS/SCO cooperation.
