Boss, tawang is a province in Arunachal and not the chinese name of arunachal, Chinese call arunachal as NEFA or North East Frontier Agency. So dont worry, the Chinese are crazy like Mad dogs about Tawang because the monastery there is supposed to be the one that validates the dalai lama everytime a new one is elected. So when the present one passes away and the Chinese impose a new one that Dalai Lama will not be valid till the Tawang Monastery approves him. But the cant happen because tawang is part of India and China has no say in that. So the Chinese will go to any means to conquer arunachal and then bhutan and sikkim because these are the other states where tibetan budhism still prevails. Even the Arunachal people say they are Indians and nobody elses so I guess the question of Arunachal being a part of India is invalid.
