Nearly two-thirds of the lake is controlled by China, with just about 45 km under Indian control. The LAC, running north-south, cuts the western part of the lake, aligned east-west. But India and China have unsettled borders, and the perception of the LAC differs in multiple sectors, including on Pangong Tso. At the lake’s north bank, according to India, the international boundary is close to Khurnak Fort, a 19th-century ruin. But the LAC, according to India, is around 15 km west. On the north bank are spurs that jut into the lake, identified as fingers. India says the LAC passes through Finger 8; China claims it is farther west.
