of India. The border is in the extreme north and is depicted as a dotted line with the caption Alignment Official Pakistan Map 1962. In 1959, the Pakistani government became concerned over Chinese maps that showed areas the Pakistanis considered their own as part of China. In 1961,
Ayub Khan sent a formal note to China; there was no reply. It is thought that the Chinese might not have been motivated to negotiate with Pakistan because of Pakistan's relations with India. In 1962 the
Government of Pakistan published an official map depicting the alignment of the northern border of Kashmir, which depicted much of the Cis-Kuen Lun Tract as part of Kashmir. The alignment published by the Government of Pakistan was mostly similar to the portrayal of the northern Border of Kashmir depicted in the 1954 Times Atlas, though in places, the Government of Pakistan's position deviated from the 1954 Times Atlas, and included areas as part of Kashmir which were to the north of the border of Kashmir shown in the Times Atlas. For an idea of the extent of the Trans-Karakoram Tract or the Cis-Kuen Lun Tract, a view the map (C) from the Joe Schwartzberg's Historical Atlas of South Asia at DSAL in Chicago with the caption, "The boundary of Kashmir with China as portrayed and proposed by
Britain prior to 1947" would show that the geographical and territorial extent of the Trans-Karakoram Tract or the Cis-Kuen Lun Tract is more or less the territory enclosed between the northernmost line and the innermost lines. After Pakistan voted to grant China a seat in the United Nations, the Chinese withdrew the disputed maps in January 1962, agreeing to enter border talks in March. Negotiations between the nations officially began on October 13, 1962, and resulted in the Sino-Pakistan Agreement signed on 2 March 1963 by foreign ministers
Chen Yi of China and
Zulfikar Ali Bhutto of Pakistan. However, the Indian political analyst and historian
A. G. Noorani claims that Shaksgam Valley never formed part of Kashmir, and that the northern and eastern boundaries of Kashmir remained undefined. The historian
Alastair Lamb, noting the Indian stance in his analysis of the agreement, states that the Indian government has repeatedly used the agreement as to claim "existence of a Pakistan-China “axis” directed towards the humiliation of India". He further adds that the western frontiers along Karakoram had been clearly established by British note to China in 1899 and its subsequent modification in 1905 had been admitted by Chinese authorities in Xinjiang during 1930s, the same border which was more or less followed during the 1963 demarcation.
Sumit Ganguly states that Pakistan gained in Shimshal Valley in return of ceding its claim over in Shaksgam. According to
Neville Maxwell, Pakistan gave up only map claims while China had to withdraw from the territory it administered. == See also ==
