I'm inclined to agree with you on Russia, but I'm not sure about China. I think the fact that they're both buying up gold is merely a coincidence.

Don't get me wrong, I'm sure that they're working together on this plan, but I think China's gold is going into corruption as a way to circumvent (and sustain) their totalitarian state in numerous ways. Gold is a traditional bribe or 'bonus' in China, and it's only become more relevant.
