Overview
In the western sector, the LAC is the de facto line between Indian- and Chinese-held areas in Ladakh. It has never been jointly demarcated, and India regards Aksai Chin as part of Ladakh.
The western sector of the LAC separates Ladakh from Aksai Chin, which is claimed by India.
Galwan valley, Depsang, Pangong Tso and Demchok are key points along it.
The 2020 clashes in Galwan led to disengagement talks, and patrolling arrangements were agreed in October 2024.
The LAC is not demarcated on the ground.
Both sides have different perceptions of where it runs.
Daulat Beg Oldi is a key Indian post.
India and China have held many rounds of talks.
