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 accede to the agreement was welcomed by the Pakistani people. Negotiations between the nations officially began on 13 October 1962 and resulted in the signing of an agreement on 2 March 1963.  It was signed by Foreign Minister Chen Yi for the Chinese and Zulfikar Ali Bhutto for the Pakistanis. For Pakistan, which had disputes between residents on its eastern and western borders, the agreement made the task easier by protecting its northern border from future competition. The treaty also provided for a clear demarcation of the border with Pakistan, which would continue to serve as a border, even after the settlement of the Kashmir dispute.  The Republic of China, based in Taiwan and generally known as Taiwan, does not recognize changes in Chinese territory based on border agreements signed by the People`s Republic of China with other countries, including Taiwan, in accordance with the Constitution of the Republic of China and its amendments. Pakistan does not recognize the ROC as a state.  During this period, China was challenged with India over the eastern border of Kashmir, with India resold the border and China claiming that such delimitations had never taken place. In their agreement, Pakistan and China acknowledged that the border had not been demarcated or demarcated, which supported the Chinese position. The agreement was moderately economically beneficial for Pakistan, which obtained pasture in the agreement, but more politically important, as it reduced both the potential for conflict between China and Pakistan and, according to Syed, “China has formally and firmly declared that Kashmir does not yet belong to India.  The 1963 period, which referred to the case, expressed the view that, in signing the agreement, Pakistan had further dampened the “hopes for a settlement” of the Kashmir conflict between Pakistan and India. As part of the Sino-Pakistan agreement, Pakistani control of part of northern Kashmir has been recognized by China.  The agreement led China and Pakistan to withdraw about 1,900 square kilometres of territory and a border on the basis of the British note to China, amended by Lord Curzon in 1899, as amended by Lord Curzon in 1905. Indian writers insisted that Pakistan had ceded 5,300 km2 of territory to China (to which they believe it had no rights). In fact, if ever, Pakistan has gained some territory, about 52 km2 (20 sq mi), south of the Khunjerab pass. [Neutrality is controversial] The claim of Pakistan was abandoned, was the area north of the River Uprang Jilga, which also enjoyed the plots of Raksam, where the Mir of Hunza had tax and grazing rights for much of the late 19th century under agreements with the Chinese authorities in Sinkiang.
