Sino Pak Agreement 1963
According to Jane`s International Defence Review, the agreement was also important during the Cold War, given that Pakistan had relations with the United States and was a member of the Central Treaty Organization and the Southeast Asian Treaty Organization.  The agreement was part of a general strengthening of the association with China for Pakistan, which led Pakistan to distance itself from the United States.    After defining the borders, the two countries also concluded trade and air agreements, including the first international agreement of its kind concluded by China with a country that was not communist.  The agreement led China and Pakistan to withdraw respectively from about 1,900 square kilometers (750 square miles) of territory 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.  After Pakistan voted to grant 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. The deal has enjoyed a moderate economic benefit for Pakistan, which has been granted pasture under the deal, but is of much greater political importance, since it has both reduced the risk of conflict between China and Pakistan and, as Syed suggests, “China has formally and firmly stated that Kashmir is not yet part of India.
