Sino-Indian War(1962); Sino-Pakistan Agreement(1963)

Sino-Indian War

In 1962, troops from the People's Republic of China and India clashed in territory claimed by both. China won a swift victory in the war, resulting in the Chinese annexation of the  region called Aksai Chin, which has continued since then. Another smaller area, the Trans-Karakoram, was demarcated as the Line of Control (LOC) between China and Pakistan, although some of the territory on the Chinese side is claimed by India to be part of Kashmir. The line that separates India from China in this region is known as the "Line of Actual Control".After That China is Holding These Territories and India has a claim of them as "Sacred Indian Soil".While Pakistan has an agreement with China on These areas after 1963 "Sino-Pakistan Agreement".

Sino-Pakistan Agreement

The Sino-Pakistan Agreement (also known as the Sino-Pakistan Frontier Agreement and Sino-Pak Boundary Agreement) is a 1963 document between the governments of Pakistan and China establishing the border between those countries. It resulted in China ceding over 1,942 square kilometres (750 sq mi) to Pakistan and Pakistan recognizing Chinese sovereignty over hundreds of square of land in Northern Kashmir and Ladakh.

In 1959 Pakistan became concerned that Chinese maps showed areas of Pakistan in China. In 1961 Ayub Khan sent a formal Note to China, there was no reply. It is thought that the Chinese may not have been motivated to negotiate with Pakistan because of Pakistan's relations with India, with which China was soon to enter a war with.

After Pakistan voted to grant China a seat in the United Nations, the Chinese withdrew the disputed maps in January 1962, agreeing to enter border talks in March. The willingness of the Chinese to enter the agreement was welcomed by the people of Pakistan. Negotiations between the nations officially began on October 13, 1962 and resulted in an agreement being signed on 2 March 1963. It was signed by foreign ministers Chen Yi for the Chinese and Zulfikar Ali Bhutto for the Pakistani.

The agreement resulted in China withdrawing from about 750 sq m of territory, and Pakistan withdrawing its claim to about 2,050 sq miles of territory (which it had not in fact occupied or administered).

China's extended territory became known as Trans-Karakoram Tract. The area is part of Kargilik County.
