I recall an article from 2009 about how Russia urged China to dump treasuries during our collapse in the fall of 2008...
Yes, i read secretary Paulson book too
I have no doubt that Russia would like to see our economy destroyed. They would surface as the good guys, the stable state etc. And they might well be willing to work with China to see that happen, as China is currently the big gorilla in the world. And yes, China buys most of its weapons from the Russians, from Russia with love. Steel cased, non corrosive, non reloadable. That is completely believable. But in the end, Russia doesn’t trust China and will hold some kind of threat over their heads. China is breaking out as the new superpower with cars and pets and designer dresses...and they want desperately to steal the Russians’ Siberian resources. Russia will definitely hold some kind of power over China...such a change in world power cannot be tolerated. Putin is still there and the KGB/FSB is still there...I would bet that there are limits established as to how far Chinese power can climb. Again, follow the money and the power.
