What are the difficulties in the Sino-Indian border issue?

The difficulty of the Sino-Indian border lies in southern Tibet, because since the Sino-Indian War 1956, China and India have been engaged in constant disputes over southern Tibet, because southern Tibet belongs to our country.

The Sino-Indian border issue refers to the border issue between China and India, which mainly includes the eastern section, Sikkim section, middle section and western section. The total length of the Sino-Indian border is about 2,000 kilometers, which is divided into three sections: west, middle and east. The western section is about 600 kilometers, the middle section is about 450 kilometers and the eastern section is about 650 kilometers. 1962, the border war broke out between the two countries because of the border dispute.

Nehru 1954 10 just returned from a visit to China, and an illegal McMahon line appeared on the official Indian map, thus forcing China to accept this fact. Until 1958 14 February 14, Nehru wrote in his personal letter to Zhou Enlai: "These large tracts of land in India (marked as belonging to China on the map of China) can only belong to India. There is no doubt about this, and these lands are not controversial. " Since then, the Indian government has also supported the rebellion of the reactionary serf owners in Tibet and publicly denied China's sovereignty over Tibet. Nehru even accused China of "failing to abide by the agreement between Tibet and China on the autonomous region and the guarantee given to India."

The failure of the Tibet rebellion shattered Nehru's delusion of designating Tibet as India's strategic buffer zone, but the idea of "Greater India Federation" still disturbed him. He openly proposed to the Indian government to transfer all the disputed land of 6.5438+0.25 million square kilometers to India, and Sino-Indian relations deteriorated immediately. Nehru completely blocked China's proposal to prevent border conflicts, pursued a "forward policy" and continued to occupy China's territory. 1962 10, Nehru issued an order to the Indian army to "drive away the China army", and the war broke out in an all-round way.
