The notion that China gonna fight a war with India for Pakistan is totally false, why will China fight a war with a nation with whom it has some $60+ billion of trade which is only going to increase in the coming years as the two Asian giants rise, & for the sake of that nation with whom it has no economic gains?? This thinking of the people of Pakistan that China will come as a savior vis-a-vis India is completely without basis, & the faster they understand this the better, there is no permanent friends in International affairs but only permanent interests, China thought that it's interests are best served by friendship with India pre-1962, so it did that, post-1962 it thought that it's interests are best served with a friendship with Pakistan so it quickly changed sides. China din't came to save Pakistan in it's hour of need in 1971, now this is 21st century where the economic relations between the nations decide the political relations between the nations. China is not going to jeopardize it's billions of trade with India for the sake of Pakistan, even if it does than what do u think, will Russia & US be watching this from the sidelines?? So what u r thinking about is the recipe of a third world war & not a defeat of India.
