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.
In all fairness, the United States is the world's largest consumer market and also China's largest import partner. So if the US imposes a complete ban and stops doing business with China, China will also suffer significant losses and there will be no market large enough to fill that void. But that also means that China is the largest supplier to the US, so they would also suffer serious damage if they lost a large and affordable supplier like China. Therefore, the scenario of them stopping doing business with each other on a large scale is unlikely. It would cause serious damage to both economies and the world.
