On a less deranged take, there’s definitely potential to mend the Sino-Soviet split. Their interests and capabilities dovetail quite a bit, but I suspect unification is wildly impractical for any number of cultural and historic reasons. OTOH, if they presented a Warsaw Pact-style alliance, perhaps using the cudgel of mutually assured economic destruction instead of nuclear destruction, that’s a hell of an act for the West to try to follow.
