The Republic of China, based in Taiwan and generally known as Taiwan, does not recognize any change 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 complementary articles. Pakistan does not recognize the ROC as a state.  Pakistan had expressed some reservations, as Chinese maps showed parts of Pakistan on their side. Ayub Khan asked for clarification, but no response was received. After Pakistan`s vote to place a seat of China on the UN Security Council, the Chinese withdrew their cards in January 1962 and agreed to start discussions on the subject. Pakistan has welcomed its willingness to reach an agreement. Talks between the two sides officially began on 13 October 1962 and resulted in an agreement signed on 2 March 1963 by Foreign Ministers Chen Yi and Zulfiqar Ali Bhutto of China and Pakistan respectively. As a result, China withdrew from the disputed area following a complaint by Pakistan. It demonstrated the aspirations of the people of both countries for the growth of friendly and fraternal relations that, in the years to come, had to play an aiding role in ensuring world peace. (i) « Every time the border follows a river, the middle line of the river bed must be the boundary. The Pakistani side leaves the southeast summit of this spur and reaches the curve of the Skgam or the Muztagh River. From this point, the border runs along the Kelechin River along the middle line of its bed along its confluence with the Shorbulak Daria.
From the confluence, the demarcation line rises to the top of the spur and crosses the main basin of the Karakorum mountain. The border between China and Pakistan had never been demarcated before. Both parties agreed to do so on the basis of tradition. The agreement, which starts from the north-western border of Pakistan at an altitude of 5,630 meters, passes from this point to the east, then southeast along the main tributaries of the Tashkurgan River, on the one hand to the tributes of the Hunza River of the Indus River on the other side, by Kilik Daban, mintake Daban, Kharchanai Daban, Kharchana daban. , the Mutsgila Daban and the Parpik Pass reach Khunjerab Daban. The Sino-Pakistan Agreement (also known as the Sino-Pakistan Border Agreement and the Sino-Pakistan Border Agreement) is a 1963 document between the governments of Pakistan and China, which defines the border between these countries.  The agreement was economically advantageous for Pakistan, as it obtained pastures in the agreement. However, it has been more politically important because it has reduced the risk of conflict between the two countries. India does not recognize that. The agreement was also very important for Cold War policy. It was part of a growing link between China and Pakistan, which began after the war between India and China.
All of this has resulted in Pakistan being shaken by the United States. In addition, the two countries also concluded a bilateral agreement on trade and air transport after the definition of borders. 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.
