Historically Tibet, East Turkistan ( Chinese call it Xing Kiang), Manchuria, Inner Mongolia and Taiwan were never parts of China. China was called Middle Kingdom, because it was only the central part of what is the Chinese Empire was China historically. All other areas were occupied by either the Communist Chgina or Kuomingtang China ( in the case of Taiwan or Formosa). This is true history. China is an imperialist country. However, that true history was unknown for the Englishman born in India, Nehru, who became the first Prime Minister only because both the British and the Birlas(the paymaster for Gandhi) wanted him. That has ruined India in the beginning. Rest is only the gradual surrender. Even in 1962, Nehru only cried but could not resist or fight back the Chinese. Now we have the worse case, a monority government with Sikh PM, Muslim vice President, a corrupt woman as president, a Christian Catholic as the leader of the ruling party and a group of pro-Chinese south Indian paracities like Karat-Yachuri as king maker. India has no future with this gang.
