How do foreign exchange reserves come from current account surplus and partial financial account surplus? For example, domestic exports are generally calculated in domestic currency, and when other countries come to buy things, they need to convert their currencies into RMB, so the currencies of these countries may flow into the People's Bank of China and become a part of foreign exchange reserves.

Foreign exchange reserves are mainly used to balance a country's international payments, regulate a country's financial market and maintain monetary stability.

Foreign exchange reserves are closely related to trade. Generally speaking, the greater a country's current account surplus, the more foreign exchange reserves it has. The more foreign exchange reserves a country has, the greater the possibility of exchange rate appreciation and the greater the negative impact on its trade.

What is usually said about how much debt a country owes a country is not what is usually said about national debt. Usually, national debt is denominated in domestic currency, and foreign debt is denominated in other countries' currencies, usually US dollars. These debts do not constitute a country's foreign exchange reserves, but the more foreign exchange reserves a country has, the less pressure it will have to repay its debts! !
