Who is "the west" in your eyes? I personally know plenty of people in the USA who are openly cheering for Russia in the conflict. So I don't think we could say that "the west" is mad at Russia. Certain people in western countries are, but plenty are quite happy with Russia and wish them well in their endeavors.
You overestimate length of the western outrage.
Anyway what's to sanction? Almost no country recognizes Taiwan. Diplomatically they changed one job in China to another
