Yes, I'm also pretty sure it was Russia. Their main business is selling energy to Europe; Russia doesn't need the US for this. Also, they know the US and Western Europe have little power to stop them from invading some of their neighbors. If the US pisses them off, then they simply turn off the tap to Germany's gas supply and we watch western economies crumble. Or they turn off the heating oil in the wintertime and Europeans freeze to death. Russia is in the most powerful position to hurt the US.
China can talk about de-coupling from the dollar economy, but the fact is they hold a lot of American debt already and China's manufacturing economy will rise or fall based on US consumer demand. So I think China is stuck with the US partnership, though they can push their agenda to some extent because the US badly needs China to keep making cheap shit and buying American debt. Isn't interdependence a wonderful thing?
