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.  China has ceded more than 1,942 square kilometres to Pakistan and Pakistan to recognize Chinese sovereignty over hundreds of square kilometres of land in northern Kashmir and Ladakh.   The agreement is not recognized as legal by India, which also claims the sovereignty of a part of the country. In addition to rising tensions with India, the agreement has shifted the balance of the Cold War by bringing Pakistan and China closer together, while easing relations between Pakistan and the United States. 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.
The agreement was moderately economicly beneficial for Pakistan, which obtained pastures in the agreement, but much more important politically, 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 Sino-Pakistan Agreement (also known as the Sino-Pakistan Border Agreement and the China-Pakistan Border Agreement) is a 1963 document between the governments of Pakistan and China that establishes the border between these countries.  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. Despite this, I have never questioned the sovereignty over the territory by Hunza, the British or the State of Jammu and Kashmir.
