1, China is the largest creditor in the United States. If it is sold, the demand for government bonds will decrease, the price will drop, and the ability of the United States to issue bonds for financing will weaken. The excessive consumption in the United States is maintained by excessive issuance of national debt, so it will cause heavy losses to the American economy.

2. It may be for political reasons, which means that the United States has reduced its dependence on China, or it may be that China's practice will prompt the United States to change its excessive consumption and twin deficits's economic situation.

3. Politically, a large number of selling will cause American retaliation, such as trade barriers. Economically speaking, compared with other treasury bonds, US Treasury bonds are still a relatively safe and liquid asset, which will lead to excessive depreciation of the US dollar in the process of selling in large quantities, causing great losses to the US dollar assets held by China.
