Dear Sir, It is no surprise that Chinese have claimed Arunachal Pradesh . The whole problem is based on some strategic blunders commited by Nehru in not challenging Chinese forceful capture of neutral territory of Tibet. Culturally and ideologically Tibet is an integral part of Greater India or Akhand Bharat . Tibet is a source of our major rivers and Kailash- Mansarovar is the holiest place for 1 billion Hindus , as holy as Vatican or Mecca . So the very idea of Chinese claim over Tibet is rubbish and Tibet actually should be either independent or a part of Greater India and since Arunachal Pradesh as the Chinese say is part of Tibet , it naturally belongs to us , so as thousands of Kilometers of other Himalayan teritory . Jai Hind.
