According to the latest data, China has become the largest holder of US Treasury bonds, which are China's main investment products. In addition, there are some real estate bonds guaranteed by the US government, holding more than 500 billion US Treasury bonds, and US dollar reserves also account for 60% of China's total foreign exchange reserves. Although we also buy some European government bonds, it is rare, because the US dollar, as the world currency, has relatively good liquidity and risk.
As the only superpower in the world, the United States ranks first in finance, science and technology, and military affairs, and its national debt security is also the highest. And the liquidity of national debt is very good. Even if China doesn't buy it, Japan will buy US Treasury bonds just like Middle Eastern oil and countries. However, with the depreciation of the US dollar, China's foreign exchange assets have shrunk, but there is no way. If you don't buy US Treasury bonds, the shrinkage may be more serious.
Therefore, there is no better solution to this problem, but relevant institutions should pay attention to it, and more aspects should seek international relevant institutions to coordinate and solve this problem. This actually shows that the interests of various countries are closely related. Although many countries seem to dislike the United States, once the United States collapses, it will still harm their interests.
