China is large enough that they don’t greatly care about global political opinion, their entire focus is on hoovering up and consolidating capital and influence while maligning any actions outside of their country that can be construed as unethical so that by lowering the bar, their dictatorship doesn’t look so bad.

Redirecting the flow of capital from Russia toward themselves is just the most recent opportunity available to them. It wouldn’t matter if it was Spain or Mexico or any other country in a weakened or different state, the whole focus of the CCP is to malign all countries more powerful than them while siphoning capital from countries both more and less powerful than themselves in an effort to lower the reputation of other countries to their levels so that the CCP can pull ahead.
