A trade in which many countries exchange goods and services is called multilateral trade. This means that there are more than two countries involved in the exchange of goods and services. Multilateral trade is conducted among members of international organizations such as the World Trade Organization (WTO) and the European Union (EU). Multilateral trade agreements are aimed at promoting free trade among countries and removing trade barriers such as tariffs and quotas. This allows countries to specialize in the production of goods and services that they have a comparative advantage in, leading to increased efficiency and economic growth.
