China got nothing to lose, even if US imposes a complete ban China will sell their products to someone else but probably for lesser profits. But the story of US is different, they can't really sustain on their own because the salary is not same as China so the government has to lower the wage policy which again will affect their citizen.
And this is not new; it also existed in the Biden period, but now it is exposed due to the unfair rates, which is probably happening due to the ego clash of an individual now affecting the whole country in one way or another.
One of the major advantage of china in the global economy is that they have the ability to produce massive quantaties of products at a relatively lower cost. And the key factor behindd this is cheap labouring cost. So every country takes advantage of that. With the availability of huge population and well developed infrastructure they are able to produce goods of anything. That is why we see made in china everywhere.
This is what the USA lacks, they certainly doesn't have cheap labour. They cannot meet the production rate as China.
