A quarter of Russia's economic exports are still not fully sanctioned, and more yet are under threat from unmanned surface vessels that have (so far) respected the civilian designation of their tankers and freighters.

China is facing the butt-end of a 30 year population crisis with a replacement rate below 0.5 in some provinces and has a subprime mortgage crisis that threatens to make 2008 look like a fairytale. They disproportionately rely on imports that cannot be sustained during a conflict and stockpiles that will not last their population even a month.
