Mercosur, or the Southern Common Market, is a regional trade bloc in South America that aims to promote free trade and the fluid movement of goods, people, and currency among its member countries. Established in 1991, Mercosur was created to enhance economic cooperation and integration among its members, which include Argentina, Brazil, Paraguay, Uruguay, and Venezuela (currently suspended). It connects to broader economic strategies such as Import Substitution Industrialization, the Washington Consensus policies, and the evolution of regional trade agreements.
