What Does the Line of Actual Control Between India and China Really Mean?

What Does the Line of Actual Control (LAC) Stand For?
The Line of Actual Control (LAC) is not a formally agreed-upon international border but a de facto boundary that separates Indian-controlled territory from Chinese-controlled territory. It stretches over 3,488 kilometers, mainly covering regions like Ladakh, Arunachal Pradesh, and Sikkim.

The concept of the LAC emerged after the 1962 India-China war, with both sides having differing perceptions of where the line lies. This discrepancy often leads to border stand-offs and military tensions. The eastern Ladakh region, in particular, has seen heightened military activity and disengagement efforts in recent years.

On July 24, 2025, India and China held a fresh round of discussions through the Working Mechanism for Consultation and Coordination (WMCC). Both sides reviewed the current status along the LAC and prepared for the next round of Special Representatives’ (SR) dialogue. The goal is to ensure regular diplomatic and military-level engagement, promote effective border management, and restore trust.
India was represented by National Security Adviser Ajit Doval, while China’s side was headed by Foreign Minister Wang Yi. The last SR dialogue happened in Beijing in December. Talks continue with cautious optimism following troop disengagements, but full de-escalation is still pending.

Despite troop withdrawals from some key friction points like Demchok and Depsang, both nations still have around 50,000–60,000 troops stationed along the LAC. The situation remains sensitive but stable. These efforts at high-level talks are essential for long-term peace and border security.
The current talks come after External Affairs Minister S. Jaishankar’s visit to China and follow previous dialogue resolutions made during a meeting between Prime Minister Modi and President Xi Jinping in October last year.
