The Depsang Plains are indeed located in the north-western part of Aksai Chin. They are strategically important due to their flat terrain, which facilitates the movement of troops and military vehicles.
The Depsang Plains are located in the northwest portion of the Aksai Chin region, and are divided by the Line of Actual Control (LAC) between India and China. India controls the western portion of the plains, while China controls the eastern portion. The Indian Army has established several forward bases in the Depsang Plains to monitor and secure the region.
The Depsang Plains are strategically important because they provide access to the Daulat Beg Oldie (DBO) airstrip and the Darbuk-Shyok-DBO road. They also provide a flat surface for military offensives, and are close to the Siachen Glacier.
