So you think Russia and the ChiComs have been staging joint war games, as recently as a few months ago, while at the same time preparing to go to war against each other. Who the heck do you think you're fooling? I hope not many.
I don’t think they want to battle each other, but the situation is all about that. It is clear that China is taking advantage of US-Russian “Great Game” in Central Asia and Russians are certainly don’t like it. Just like they don’t like a Chinese immigration and overall growing economic dominance over Far East.
