A free-trade area is a concept that refers to a geographic area that has minimal restrictions on imported and exported goods and services. To describe this area, there are several synonyms that can be used, such as customs union, trade bloc, open market, free market, and economic alliance. Each of these phrases conveys the idea that there are few, if any, barriers to trade between the participating countries. Additionally, these synonyms are often used interchangeably to describe the same economic relationship, as they all share the fundamental characteristic of promoting increased trade and economic cooperation among member nations. Regardless of the term used, free-trade areas are an essential component of modern international commerce.
