It is interesting to note that Bhutto, invoking Article VI of the 1963 agreement, told the UN Security Council: “Under international law, the right to conclude treaties and agreements is an attribute of sovereignty. Moreover, a sovereign cannot expect to hold sovereign functions in any territory other than his own. In light of the United Nations resolutions of 17 January 1948 and 13 August 1948 and 5 January 1949 (UNCIP resolutions), it is clear that Pakistan cannot (and cannot) claim sovereignty with regard to J-K. Pakistan`s motivation to offer the Shaksgam Valley to the People`s Republic of China has been driven by a short- and medium-range destination, as the agreement undoubtedly does not solve the Kashmir problem, but has resulted in legal recognition of Pakistan`s de facto control over Pakistan`s occupied Kashmir. After the border agreement, some experts believed that China had entered into an informal military alliance with Pakistan. What is clear from a statement by Zulfikar Ali Bhutto (then Foreign Minister) to the National Assembly in July 1963 “An attack by India against Pakistan involves the territorial integrity and security of Asia`s largest state,” said Zhou-en-Lai, the first Prime Minister of the People`s Republic of China (PRC), a Pakistani group that would visit China with goodwill. , that his country would defend Pakistan around the world. 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.  Today, China is spending an additional $18 billion to build a 200-kilometre tunnel in Gilgit-Baltistan, which will support rail traffic between Kashgar and the port of Gwadar in occupied Balochistan. The agreement was signed by Pakistani Prime Minister Nawaz Sharif, who also agreed to establish China-run industrial zones along the Karakorum Highway and deploy fiber optics over the Karakorum Mountains. Why is the mention of Shaksgam a topic for Beijing? On March 27, 1963, an agreement was signed between Pakistan and China on parts of the Kashmir border with Xinjiang. On December 27, 1962, it was learned that an agreement in principle had been reached.
The agreement was signed in Beijing on March 2, 1963. On March 26, 1965, a border protocol was signed to characterize ground positions. Over the coming decades, and more, the award-winning qualification has given way to a general affirmation. On 10 August 1994, The Minister of State for Foreign Affairs R.L. Bhatia told Rajya Sabha that “as part of the agreement, Pakistan illegally ceded about 5,120 square kilometres of Indian territory” in Pakistan-occupied Kashmir to China (The Hindu, August 11, 1994). The agreement was based on the Karakorum Basin and not on the Kuen Lun; On the Macartney-MacDonald offer of 1899, as varied curzon on the Shimshal Pass in 1905, and not on the Ardagh line of 1897. During this period, China was the subject of controversy with India over the eastern border of Kashmir, with India resold the previously demarcated border and 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 1963 China-Pakistan border agreement is a perfect example of a very popular phrase “politics makes strange bedmates”.
