Wouldn't the result of Russia losing all it's allies be an even more unstable situation? Assuming others follow suit to China, tho I have no idea how realistic that is, for instance India isn't close to China AFAIK. Barring an internal coup, in the desperation of getting truly economically and politically isolated I could imagine an angry autocrat going for an true all-in.
