When did China become a South Asian country?
Chinese air force made of copied technologies and borrowed engines and operating against India from 7000 feet Tibet plateau has more disadvantages than their huge numbers. These numbers are made up to intimidate the adversary. Moreover a bulk of their inventory of 1200 planes are trainers. The latter are no threat.
Relax, China is no serious threat to anybody including India. Now with Japan deciding to amend its pacifist constitution, a much bigger threat to China has begin to emerge. Rise of Japan sends shiver thru the Chinese spine. It would have been better if Chinese had left Japan alone and raised no territorial ambitions against them. But over confident Chinese flush with excessive US merchandise cash wished to exert themselves. Now they have and awoke Japan.
Good for India; Chinese needed an enemy with better technological prowess, now they have found it.
Truly, It is the American in their excessive zeal to surround Soviet Union in eighties created China. Now US as onlooker would see rise of Japan and the whole Pacific equation would change.
Now US would have to rethink that wasting energies to beat up little guys in Vietnam, Afghanistan, Iraq, Serbia, Panama and other Caribbean Islands make them great or confronting somebody of their own size makes them great.
