Both china and russia view the US as a bigger threat then each other.
Yeah, right now that is true. The scenerio that could unfold could be like that of WWII where Hitler and Stalin are allies and then Hitler invades Russia while they are busy with the Japs in the far east. This time would be the Chi-coms doing the back-stab while Russia engaged with Europe/USA. These guys may have learned from history and playing Sun Tzu by the numbers, but evil nations/groups always back-stab each other in the end.
