On the one hand, pretty easy to see why the US would be looking for ways to stop Chinese drones getting in. Various US-backed entities have demonstrated that sleeper cells of drones are a pretty reasonable attack vector and the Chinese would be crazy not to try and prepare some sort of latent drone attack force in the US given that they are probably next on the chopping block after the US is done with Russia. Plus drones are very militarily strategic and China appears to have achieved an overwhelming dominance in the market which bodes well for them. US leadership must be quite unhappy about that and looking to try and salvage what they can of their local capabilities.

On the other hand, I doubt they can really stop China and it is amazing watching the US first position themselves to reject manufacturing as an undesirable industry, then start blocking imports from the globe's foremost industrial superpower as they realise that industrial capacity wins wars. There is a level of incoherence here - how does the US intend to run an advanced industrial society if it won't accept local pollution and won't accept goods from the places pollution is outsourced to?

Depending always on how misleading the Chinese figures are, the US doesn't have the globe's preeminent economy any more. They appear to be #2 or very close to becoming it. They're going to have to re-learn how to engage with a larger more industrially successful power and keep on good terms with people through diplomacy.
