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.
It's not like China won't be affected at all. The USA is a big market for China and the rest of the world. You can sell something at a better price to the US people. Yes, people in the USA will indeed face the consequences. China is the factory of the world; you can produce anything in China at a very cheap price, while the USA cannot produce the same product for the same price.
If the USA decide to produce everything on its own, then either they will have to minimise the cost by lowering the salary, or they will have to sell the product at a very high price. No matter what the USA says, it's not possible for them to produce everything on their own.
China has really been shaken off on the huge tariff implemented by Trump that's why they are condemning them and try to solve this issue in more convenient way.
US consumer would really face the consequences since instead they can buy cheap product the same as before, now they might spend more because of these tariff issues which the importer need to do so that their business can survive on this huge crisis they currently facing.
Well if they can produce their own product then its good to them, but I believe they are lacking of resources and China have almost all of that. This is why in long term US might be in big trouble especially that there's huge chance for China to change their trade route while US consumer will continue to get a problem with high prices of products they buy.
For sure somehow Trump just want what's best for US, but they didn't expect that worse situation will happen and now they face this consequences and engage much on more bigger problems.
