During the upcoming visit of Indian Prime Minister to China, India must clearly make the China to understand that Macmohan Line that demarkates the actual boundary between Tibet and Indian was agreed in the treaty made among British India, Tibet and China. So, according to that treaty, Whole Arunachal Pradesh comes under India. Arunachal Pradesh is not a disputed area at all. Moreover, Tibet was hostorically an independent country and China has no right to claim it as part of China. Instead as British India invaded Tibet and controlled Tibet, India has every right to claim Tibet as its part.
