India–China relations are the diplomatic, economic and strategic ties between India and China. The relationship has combined periods of cooperation, especially in trade and multilateral forums, with persistent rivalry driven mainly by an unresolved border dispute and wider geopolitical competition.

Historical background

India and China developed formal diplomatic relations in 1950 after a long historical connection. Relations deteriorated sharply after the 1962 war, but later improved at several points, including the 1988 visit by Rajiv Gandhi and the 2003 and 2005 agreements on broader cooperation.

Border dispute and security tensions

The unresolved boundary question, associated with the Line of Actual Control, is the main source of friction. It has led to clashes and standoffs, including the 1962 war, the 2020 Galwan Valley violence and continuing military deployments.

Economic and institutional ties

Despite strategic tension, the relationship has included deep economic interaction and many formal dialogue mechanisms. India and China have maintained trade, financial and scientific cooperation, and official sources describe more than thirty bilateral dialogue mechanisms.

Multilateral cooperation and rivalry

India and China coordinate in some international institutions and share interests on issues such as climate change and global governance. At the same time, they compete for influence in Asia and among developing countries.

Key facts

  • India established diplomatic relations with the People’s Republic of China on 1 April 1950.
  • The 1962 border conflict caused a major setback in bilateral ties.
  • China was India’s largest trading partner from 2008 to 2021, but India’s trade balance has been heavily deficit-based toward China.
  • The two countries cooperate in several multilateral settings, including the UN, WTO, BRICS, G20 and the Shanghai Cooperation Organization.
  • In recent years, both sides have sought cautious de-escalation and dialogue after the 2020 Galwan Valley clashes.

Canadian context

Canada is indirectly affected through global trade, Indo-Pacific security, and multilateral diplomacy, since India–China tensions influence economic supply chains and broader international relations relevant to Canadian foreign policy.
