阿克赛钦
From 1917 to 1933, the "Postal Atlas of China", published by the Government of China in Peking had shown the boundary in Aksai Chin as per the Johnson line, which runs along the Kunlun mountains. The "Peking University Atlas", published in 1925, also put the Aksai Chin in India. When British officials learned of Soviet officials surveying the Aksai Chin for Sheng Shicai, warlord of Xinjiang in 1940–1941, they again advocated the Johnson Line. At this point the British had still made no attempts to establish outposts or control over the Aksai Chin, nor was the issue ever discussed with the governments of China or Tibet, and the boundary remained undemarcated at India's independence.
