The agreement was therefore of the utmost importance, since it is the history of bilateral relations between the two states. Not only has it resolved the border dispute between the two countries, but it has also helped to establish friendly relations between them. But in other respects too, it was important that the agreement had weighed on Pakistan`s relations with the West and dealt a blow to the Kashmir conflict. According to Jane`s International Defence Review, the agreement was also important during the Cold War, as Pakistan had ties to the United States and was a member of the Central Treaty Organization and the South Asian Treaty Organization.  The agreement was part of a general strengthening of the Pakistan Association, which led to the secession of Pakistan from the United States.   After the delimitation of the borders, the two countries also concluded agreements on trade and air travel, the latter of which was China`s first international agreement with a non-communist country.  For Pakistan, which had border disputes on its eastern and western borders, the agreement made the task easier by securing 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 Pakistan-China border agreement for the Pakistan-China border was signed in March 1963. This agreement has become quite controversial because of India`s refusal to recognize it, because it also claims sovereignty over some of the territories. In addition to this controversy, the agreement has altered the regional balance by bringing Pakistan and China closer together, while weighing on Pakistan-U.S. relations. The agreement led China and Pakistan to withdraw from about 1,900 square kilometers of territory and a border based on the British note of 1899 to China, as amended in 1905 by Lord Curzon.
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.
