The Sino-Indian border war was 1962. The border guards of the Indian People's Liberation Army stationed in Tibet and Xinjiang fought back in self-defense against the Indian army invading China's territory, which India called the Walloon War. After the People's Liberation Army entered Tibet, it bordered on Indian territory, resulting in a series of territorial problems.

After the talks between the two sides broke down, the Dalai Lama Tenzin Gyatso fled to India for asylum on 1959, and Sino-Indian relations began to deteriorate. Later, a series of crossfire conflicts led India to set up military positions in southern Tibet, and sent troops to cause this war. The Cuban missile crisis in the United States and this war broke out almost at the same time.

Part of the reasons for the Sino-Indian War:

1, Britain has laid the bane of the Sino-Indian border dispute.

China and India have a long history of communication and traditional friendship. The maps of the two countries mark the boundaries according to the traditional custom line, and the people of both countries abide by this traditional custom line. However, after Britain ruled India, the British and Indian authorities pointed the finger of aggression and expansion at the southwestern and northwestern border areas of China. The British and Indian governments arbitrarily demarcated the so-called "McMahon Line" on the grounds that the Sino-Indian border had never been formally demarcated, and carried out aggression and expansion activities in China, Tibet, Xinjiang and other places, laying the bane of Sino-Indian disputes.

2. Indian occupation of China territory after independence.

1947, after Indian independence, it not only wanted the China government to recognize the "McMahon Line", but also occupied the territory of China under the jurisdiction of the China government.

After India's independence, the local government in Tibet believed that India was out of British jurisdiction and Tibet should also get rid of the privilege of British occupation. To this end, the local government of Tibet has made representations to India's "representative office" in Lhasa. In response to the reasonable demands of the local government in Tibet, the Indian government, with the arrogance of a big country, announced that it would inherit the "McMahon Line" delineated by the British emperor. Although the British invaders concocted the "McMahon Line", they did not dare to invade the area north of the traditional custom line between China and India for a long time.
