evidence: India claims Aksai Chin, which is administered by China. During the 1950s, the People's Republic of China built a 1,200 km (750 mi) road connecting Xinjiang and western Tibet, of which 179 km (112 mi) ran south of the Johnson Line through the Aksai Chin region claimed by India.[18] Aksai Chin was easily accessible to the Chinese, but was more difficult for the Indians on the other side of the Karakorams to reach.[18] The Indians did not learn of the existence of the road until 1957, which was confirmed when the road was shown in Chinese maps published in 1958.[19] [...] Arunachal Pradesh is a state of India created on 20 January 1972, located in the far northeast. It borders the states of Assam and Nagaland to the south, and shares international borders with Burma in the east, Bhutan in the west, and China in the north. The majority of the territory is claimed by China, by whom it is called South Tibet.[23] The northern border of Arunachal Pradesh reflects the McMahon Line, a line demarcated by the 1914 Simla Convention between the United Kingdom and the Tibetan government. The Simla Convention was never accepted by the Chinese government, and it was also considered invalid by Tibetans due to unmet conditions specified in the treaty.[24] The boundary was not broadly enforced by the Indian government until 1950. Currently, this territory is administered by India.[25][26]
