Protectionism is the economic policy of restraining trade between states through methods such as tariffs on imported goods, restrictive quotas, and a variety of other government regulations designed to allow (according to proponents) "fair competition" between imports and goods and services produced domestically.
This policy contrasts with free trade, where government barriers to trade are kept to a minimum. In recent years, it has become closely aligned with anti-globalization. The term is mostly used in the context of economics, where protectionism refers to policies or doctrines which protect businesses and workers within a country by restricting or regulating trade with foreign nations.
