The Line of Actual Control (LAC) is a demarcation line that separates Indian and Chinese territories in the region of Ladakh. It is not a formally recognized border but rather a practical boundary that has emerged from historical conflicts and military engagements between the two countries. The LAC is significant because it helps manage the territorial disputes between India and China. Both nations have differing perceptions of where the LAC lies, leading to occasional tensions and standoffs. Understanding the LAC is crucial for grasping the complexities of Indo-Chinese relations and regional security dynamics.
