The US definitely cares where that happens. They could give a rats ass if every stupid trinket, knick-knack, or unsophisticated gadget was manufactured in China.
What they care very deeply about limiting is high-tech developments, semiconductor fabrication, and heavy industry.
These pose a serious threat to the US's ability to subjugate the rest of the world into allowing indefinite extraction of natural resources. Why do business with the West when China will provide technology that is of equal or superior quality with fewer strings attached? China has an extremely low bar to clear in terms of equality of exchange, and only needs to keep developing itself to put an end to US hegemony.
At which point, the rest of the world can sanction and exclude the West because the West largely extracts while producing very little in terms of material goods.
Unsurprising really. It seems fairly apparent that gravity merely influences the geometry of the substrate in which all known forms of matter & fundamental forces operate within. Something would have to seriously be fucky for antimatter to act counter to that geometry given it is comprised of similar particles with opposite charge. I'd assume astrophysicists know this, but wanted experimental proof for what seems to be straightforward logic from things we have experimentally confirmed.
The real question is what form does this geometry use to exert influence on the matter operating within curved spacetime? How is that information carried and how does gravity interface with that?

Tons of intense, short-lived hobbies is one of the biggest hallmarks of ADHD.
Over-prevalence of this notion does a lot more harm to me than people wrongly identifying with the OP.
