In short, after an enterprise obtains foreign exchange for its export commodities, it must sell the foreign exchange to the country, and the country's foreign exchange reserves will increase.

Enterprises can only pay for imported goods by buying foreign exchange from the state, and the state's foreign exchange reserves are reduced.

Therefore, China's foreign exchange reserves are not controlled by the state at will, but are directly related to China's trade situation. The trade surplus reserve increased and the trade deficit reserve decreased. Not the country wants to reduce it.
