I think that would be enough to unify China/India/everyone else against Russia followed by the cracking of Russia into separate countries

Are there natural “fault” lines for Russia to split into?

Ethnic Russians are in the minority in some places https://commons.wikimedia.org/wiki/File:Percentage_of_Russia... so some people might try to secede and set up a new nation state. Well, it's been tried before in Chechnya and in the end Russian troops reconquered the territory. But if the Russian military appears sufficiently weak, separatists might try again.

Just draw lines like in Africa. This will ensure decades of turmoil
