Does this so anything? Iirc China had already flexed a bit on rare earth metal sales to the evil empire, can’t buy weapons from these companies under American law, and I doubt they are selling weapon components to American companies.

The anglo stenographer who wrote this thinks this is just for show and I can’t tell if that’s copium or an accurate assessment.

This might actually be a bit worrying. The US can’t really justify a war with China when half the components in their weapons are made there. But if China sanctions the US, they can shift production away from them.
