Free trade is a policy in international markets in which governments do not restrict imports or exports. Free trade is exemplified by the European Union / European Economic Area and the North American Free Trade Agreement, which have established open markets. Most nations are today members of the World Trade Organization multilateral trade agreements. However, most governments still impose some protectionist policies that are intended to support local employment, such as applying tariffs to imports or subsidies to exports. Governments may also restrict free trade to limit exports of natural resources. Other barriers that may hinder trade include import quotas, taxes and non-tariff barriers, such as regulatory legislation.
