What is the policy of China's engagement with her neighbours?

In my opinion, China does not want to engage in any conflict with her neighbors. But, since the times of Zhou Enlai, Premier of China from 1949-1976, she has deliberately tried to disengage with her neighbors, by being aggressive, and not following her aggression with intent. The People's Republic of China is more concerned, rather very concerned, with her internal security, and her internal integrity. I do not know how influential, the international policies of Mr Zhou Enlai are today, in China, but China seems to be engaging in a milder form of the diplomacy practiced from the days of Zhou Enlai. Perhaps, the genesis of this policy, has to do with the foreign occupation of China, before the advent of the communist regime. If I may quote Encyclopaedia Britannica, "Renowned for his charm and subtlety, Zhou (Enlai) was described as affable, pragmatic, and persuasive." Mr Jawaharlal Nehru, must have been suitably impressed by Mr Enlai, too. Mr Jawaharlal Nehru coined the phrase, "Hindi-Chini Bhai Bhai", for the benefit of the Hindi speaking masses, which ment, "Indians and Chinese are brothers". However, his sentiment was rended, by the Chinese aggression. What hurt Mr Nehru, perhaps, was his estimation of Mr Enlai.
