介绍:
30.Free trade is an economic policy under which the government does not interfere with trade. No tariffs are applied to imports or exports, and people are allowed to trade goods and services as they please. Supply and demand dictates the prices for which goods and services sell and are the only factors that determine how resources are allocated in society. 微信 hwdfxy
