That said, China has traditionally looked to the US for an alignment against Russia. It was one of the central reasons why we were able to win the Cold War.
That said, the balance of power in East Asia is veyy different now. China is Russia's largest trading partner, and Russia is China's major arms supplier. They have no interest in fighting one another. Even if they did, I just don't think the Chinese have much to fear from the Russians right now. It would make no sense for the Russians to try anything, and if they did the Chinese would eat them for dinner. The Chinese military is in much better shape, and Russia would have serious supply issues given that it is dependent on basically one road system to supply the entire Far East.
Well, its nice to see you occasionally acknowledging some facts.
First, the Nixon opening to Communist China (and the Communist Chinese response) was not based on mutual admiration, but rather on mutual weakness and fear of (the Soviet) aggression.
Second, what country was supplying the largest propotion of Germany's food supply prior to June of 1941?
What country had the highest trade with Germany in 1938?
So much for your "trade" argument.
Third, the "road" system the Russians are depend upon is actually a "rail" road!
