Sino Pak Boundary Agreement
The agreement led china and Pakistan to withdraw from about 1,900 square kilometers of territory (750 square miles) and a border based on the 1899 British note to China, modified by Lord Curzon in 1905. Indian writers insisted that, in this transaction, Pakistan ceded 5,300 km2 (2,050 square miles) of territory to China (which they believe had absolutely no right). Indeed, if at all, Pakistan has gained some territory, about 52 km2 (20 square miles), south of the Khunjerab Pass. [Neutrality is controversial] The claim abandoned by Pakistan was the area north of the Uprang Jilga River, which also included the Raksam lands, where the Mir of Hunza had enjoyed tax rights and pastures for much of the late nineteenth century under agreements with the Chinese authorities in Sinkiang. Despite this, sovereignty over the territory has never been questioned by the Mir of Hunza, the British or the state of Jammu and Kashmir.  For Pakistan, which had border disputes on its eastern and western borders, the agreement brought relief by securing its northern border from future competitions. The treaty also provided for a clear demarcation of the border with Pakistan, which would continue to serve as the border even after the settlement of the Kashmir dispute.  The two sides also agreed that the two sides will resume talks on the border issue in the context of the settlement of the Kashmir conflict. After Pakistan voted to give China a seat at the United Nations, the Chinese withdrew the controversial cards in January 1962 and agreed to begin border talks in March. The willingness of the Chinese to join the agreement has been welcomed by the Pakistani people. Negotiations between nations officially began on October 13, 1962 and culminated in the signing of an agreement on March 2, 1963.  It was signed by Foreign Ministers Chen Yi for the Chinese and ali Bhutto for the Pakistanis.

Pakistan does not recognize the ROC as a state The border between China and Pakistan had never been demarcated before….
