Doklam
Doklam (Tibetan: འབྲོག་ལམ།, Wylie: ‘brog lam, THL: drok lam), called Donglang (Chinese: 洞朗) by China, is an area in Chumbi Valley with a high plateau and a valley, lying between China's Yadong County to the north, Bhutan's Haa District to the east and India's Sikkim state to the west. Since the 1960s, China and Bhutan have disputed sovereignty over the Doklam area.
