India–China Relations

India and China are Asia's two civilisational powers and nuclear-armed neighbours whose 3,488 km disputed Himalayan boundary — the Line of Actual Control — has never been formally demarcated. The relationship swings between deep economic interdependence and recurring military standoffs, most gravely the 2020 Galwan Valley clash, the first deadly border fighting in 45 years.

Where the relationship stands

India–China relations are defined by a structural paradox: China is among India’s largest trading partners, yet the two armies remain in a hardened forward posture along the Line of Actual Control after the 2020 Galwan clash. New Delhi’s response has fused military de-risking (accelerated border infrastructure, forward deployments) with economic de-risking (scrutiny of Chinese investment, import substitution in electronics and pharmaceuticals).

The three theatres

The land border. The unresolved LAC — western (Ladakh), middle, and eastern (Arunachal Pradesh) sectors — is the flashpoint. Disengagement since 2024 has eased the immediate crisis without resolving the underlying claim.
The maritime and neighbourhood contest. Both powers compete for influence across the Indian Ocean littoral, from ports to lending, and across South Asia’s smaller states.
The multilateral hedge. India cooperates with China inside BRICS and the SCO while deepening the Quad with the US, Japan and Australia — a deliberate two-track posture.
