Doklam

Doklam, called Donglang by China, is an area in Bhutan with a high plateau and a valley, lying between China's Chumbi Valley to the north, Bhutan's Ha District to the east and India's Sikkim state to the west. It has been depicted as part of Bhutan in the Bhutanese maps since 1961, but it is also claimed by China. The dispute has not been resolved despite several rounds of border negotiations between Bhutan and China. The area is of strategic importance to all three countries.
