Francis Watson, in Frontiers of China, provides a possible clue for the unsubstantiated claims made by China in Himalayas. ‘He avers that China’s historical notions of natural frontiers reflect a preference for looking down on a neighbour from the frontier. This would explain why the Ching dynasty and even the 1954 map of the People’s Republic showed Nepal, Bhutan, Sikkim, northern Burma, half of Vietnam and of course NEFA (Arunachal) as part of the domain of China.’
