First of all, a large amount of US Treasury bonds can be used to buy foreign products to recover bonds, such as American high-tech products and foreign military products, but relatively speaking, US arms sales to China are strictly prohibited.

China can sell US Treasury bonds to other countries, but this is a drop in the bucket compared with a large number of US Treasury bonds at home.

The country's hoarding of a large number of US Treasury bonds has a deeper thinking. These US Treasury bonds are a threat to American credit, that is, they can be used as bargaining chips in political and economic negotiations with the United States.

If Sino-US relations are not good in the future, we can crack down on American finance and American national credit by selling US Treasury bonds.
