The US sanctions have nothing to do with free market maximalism. I thought that was quite obvious historically and specially now. They've imposed tariffs on literally every country on the planet.
But the "banned" chips this article is referring to and the original chips act is from the Biden administration, having nothing to do with the current tariff climate.
Also, obviously US actions have nothing to do with free market maximalism. Nor does China feel that way either. Which is my point.
