There is no doubt. This is an alliance of convenience and I think in Russia's minds they are probably viewing this as like their Stalinist predecessor's alliance with Britain and America fighting against the Soviet Union. Once the enemy (i.e. the US) disappears, it will be the time to turn the gun barrels around and fight against China and the EU over the spoils that is the world.
They wouldn't have a snowballs chance in hell, if it weren't for 33% of the US, and their representitives in government, who hate themselves and would rather see China rule than Pax Americana.
