Free trade is a trade policy that does not restrict imports or exports. In government, free trade is predominantly advocated by political parties that hold economically liberal positions, while economic nationalist political parties generally support protectionism, the opposite of free trade.
Most nations are today members of the World Trade Organization multilateral trade agreements. States can unilaterally reduce regulations and duties on imports and exports, as well as form bilateral and multilateral free trade agreements. Free trade areas between groups of countries, such as the European Economic Area and the Mercosur open markets, establish a free trade zone among members while creating a protectionist barrier between that free trade area and the rest of the world. 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.
