The role of foreign trade:

Foreign trade not only connects countries with highly developed commodity production, but also enables countries and regions with low production development level to join the exchange field through foreign trade, so that currency, as a universal equivalent, penetrates into their economic life, making the labor products of these countries and nations more and more commodity and exchange value, and the law of value gradually dominates their production.

With the development of commodity circulation in various countries, the functions of gold and silver as world currencies are increasingly enhanced. Gold and silver are not only used as general means of currency purchase, but also as means of international payment, international settlement and international credit. As gold and silver become the world currency, it is possible to form the world price of commodities.

The formation of world price indicates that the role of law of value extends to the world market, which lays a foundation for the comparison of commodity production and exchange conditions in various countries and promotes the development of world production and trade.

Through foreign trade, participating in international division of labor and saving social labor, we can not only make full use of the resources of various countries, but also ensure the smooth progress of social reproduction and accelerate the realization of social expansion and reproduction.
