If the dollar collapses, will China collapse?

At present, the US dollar is the main currency or even the only currency for foreign trade settlement. China's economy is closely related to foreign trade, so it is inseparable from the US dollar. Even if you don't charge dollars when you sell it, you have to pay dollars when you buy it. If we don't accept it, we can't take out dollars to buy it. So China has $3 trillion in reserves. If the dollar collapses, first of all, the value of more than 20 trillion will definitely become waste paper. Moreover, the collapse of the dollar not only led to the collapse of the dollar system, but also led to the credit collapse of the paper money system. In other words, any country will no longer believe in paper money as a trading medium. Even if the US dollar collapses, China can stabilize its domestic monetary system through policy regulation, but any currency will lose its credit in foreign trade transactions, so it is estimated that it can only keep the RMB circulating in China. Some people say that the dollar will be replaced by gold. Of course, this is a possibility, but the problem lies in the pricing of gold. From the collapse of the US dollar to the re-establishment of the standard of circulation media recognized by both parties in international transactions, all countries need to discuss and determine. It will take a long time to re-establish a system, during which all industries that rely on foreign trade will stagnate and collapse. China is the only country with a complete industrial system. It is a fact that our life will be better if we rely on foreign trade. Without foreign trade, we can manufacture and buy most things, and we have systematic advantages. In addition, our financial institutions are all government-controlled and have regulatory advantages. Therefore, I think that if the US dollar collapses, China will definitely not collapse, and it may be one of the countries with the least losses in the world, but no one can estimate how much the economy of China will be affected on this day.
