India-China relations: border, trade, and trust
India and China are neighbours, major economies and rivals whose relationship mixes cooperation with deep mistrust. The core difficulty is the border. India and China share a disputed boundary known as the Line of Actual Control (LAC). India describes its length as about 3,488 kilometres, while China gives a different figure, and the line has not been fully delineated or demarcated. Aksai Chin is administered by China and claimed by India; Arunachal Pradesh is administered by India and claimed by China as South Tibet. These competing claims mean that even a local patrol can become a diplomatic incident.
Trust collapsed in June 2020, when soldiers clashed in the Galwan Valley in Ladakh. Twenty Indian soldiers were killed, and China later officially acknowledged four of its own soldiers killed — the first deadly clash on the border in 45 years, according to several accounts. India responded with restrictions on some Chinese investment and apps, citing national security, and both sides built up forces along the LAC. Disengagement at friction points in eastern Ladakh was completed in October 2024, according to reports of that agreement, but de-escalation — a return to earlier troop levels — remained a separate, unresolved step.
Since then, diplomacy has cautiously resumed. Prime Minister Narendra Modi met President Xi Jinping in Tianjin on 31 August 2025, on the sidelines of the Shanghai Cooperation Organisation summit, in what was described as Modi's first visit to China in seven years. The two sides discussed resuming direct flights, reopening border trade routes including Nathu La, Lipulekh and Shipki La, and improving border management. Analysts quoted in coverage of the thaw described it as driven in part by economic pressure, including United States tariffs, rather than by a settlement of the border dispute.
Trade tells a second story. India imports far more from China than it exports to it, especially electronics, machinery and chemicals. Reported estimates for 2025–26 put the goods trade deficit above $100 billion, though exact figures differ between Indian, Chinese and think-tank estimates, so the precise total should be treated with care. For students, the lesson is that border, trade and trust cannot be separated: commerce can continue while soldiers remain deployed, and a thaw in meetings does not by itself mean a thaw in security.
Key takeaways
- The LAC is disputed and undemarcated, which makes management, not just settlement, a permanent task.
- Galwan in 2020 broke trust; disengagement in 2024 did not by itself restore it.
- Trade has grown even as the security relationship remains tense, creating a large and politically debated deficit.
Why it matters for civil studies: India-China questions test whether you can hold border, economic and domestic-politics factors together instead of treating them as separate chapters.
Discussion question: Can India reduce its trade dependence on China without harming its own manufacturing and consumers — and who should decide that balance?
