In order to avoid a sharp depreciation of the dollar, the United States needs a strong dollar to support its economy.

Of course, the United States borrowed money from China. China has creditor's rights.

In order to protect the stability of foreign exchange reserves, China has made it clear that the United States should keep the dollar stable.

Simply put, the cost of printing a $65,438+000 bill in the United States is a few cents. With these pennies, we can get the equivalent wealth of $65,438+000 (of course, this banknote will circulate abroad). For a simple example, there are only 100 resources and 100 dollars in the world, so 1 resources are 1. When the United States issues another $65,438+000, the resource will become $2. In the past, 1 USD could be exchanged for 1 resources, but after issuing currency, 1 USD could only be exchanged for half of the resources.
