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. In June 2017 a military standoff occurred between China and India, as China attempted to extend a road on the Doklam plateau southwards near the Doka La pass and Indian troops moved in to prevent further road construction. India claimed to have acted on behalf of Bhutan, with which it has a 'special relationship'. Bhutan has formally objected to China's road construction in the disputed area. Geography The Imperial Gazetteer of India, representing the 19th century British view of the territory, states that the Dongkya range that separates Sikkim from the Chumbi Valley bifurcates at Mount Gipmochi into two great spurs, one running south-west and the other running south-east. Between these two spurs runs the valley of the Dichu or Jaldhaka river. However, the Dongkya range that normally runs in the north–south direction gently curves to east–west at the southern end of the Chumbi Valley, running through the Batang La and Sinchela passes and sloping down to the plain. A second ridge to the south, called the Zompelri or Jampheri ridge, runs parallel to the first ridge, separated by the Doklam or Doka La valley in the middle. At the top of the valley, the two ridges are joined, forming a plateau. The highest points of the plateau are on its western shoulder, between Batang La and Mount Gipmochi, and the plateau slopes down towards the southeast. Between the two ridges lies the valley Torsa Nala (called Doklam River by the Chinese), which joins the Amo Chu river about 15 km to the southeast. The 89 km2 area between the western shoulder of the plateau and the mouth of Torsa Nala is called Doklam by China. In the Tibetan language, "Doklam", or more properly "Droklam", means a nomad's path. The said path can be seen in Maps 5–7, which runs from the village of "Shuiji" in the vicinity of Sangbay (Sangbe), climbing up
