Foreign exchange control refers to the restrictive measures taken by a government to balance the international payments and maintain the exchange rate of its own currency. It is also called foreign exchange management in China. After receiving the export payment, you must declare to the foreign exchange administration department and sell all or part of the foreign exchange to the designated foreign exchange bank according to the official exchange rate and management regulations. In addition, in order to encourage exports, many countries implement export tax rebates, export credits and other measures, and at the same time restrict the export of some commodities, technologies and strategic materials that are urgently needed, in short supply or have a significant impact on the national economy and people's livelihood, and usually implement an export license system.

In order to restrict the import of certain commodities and reduce foreign exchange expenditure, the general measures are: the prepayment system of import deposit: when importing a certain commodity, the importer must deposit a certain amount of import payment into a designated bank, and the bank does not pay interest. The amount is determined in a certain proportion according to the category of imported goods or the country to which it belongs. Import license system: this means that importers can only buy foreign exchange needed for import if they obtain an import license issued by the relevant authorities. The issuance of import licenses usually takes into account the import quantity, the structure of imported goods, the country of production of imported goods and the terms of import payment.
