China's US$ 3 trillion foreign exchange reserves seem to be quite large. In fact, they may not be used. In 215, foreign exchange reserves fell rapidly, ending the situation of rising for 22 years. The depreciation of RMB and capital outflow have accelerated the consumption of US dollars.

some of these investments may be illiquid or difficult to realize. Other investments may suffer losses, but the losses are not included. In addition, some of the reserves may have been used as funds for projects that the government is trying to promote, such as the Silk Road Fund. There are other liabilities that China must pay, such as foreign debts in foreign currencies.
