That's pure wishful thinking. Russia spans 11 time zones, but most of Russia's population lives near Europe, west of the Ural mountains. They have as little to do with China as other people of Europe. The "mental center" of Russia is close to Eastern Europe, and their greatest ambition is to dominate the continent, for a variety of reasons that would take too long to explain. They see the US as the archenemy, because the US has stood in their way since the end of WWII.

Russia is willing to play an ally, but only insofar as it brings them closer to what they really want: Europe. Anyone who doubts this is utterly clueless about Russia and not worth listening to.
