Mercosur

Mercosur (in Spanish), or Mercosul (in Portuguese), officially Southern Common Market, is a South American trade bloc established by the Treaty of AsunciĂłn in 1991 and Protocol of Ouro Preto in 1994. Mercosur's purpose is to promote free trade and the fluid movement of goods, people, and currency. Since its foundation, Mercosur's functions have been updated and amended many times; it currently confines itself to a customs union, in which there is free intra-zone trade and a common trade policy between member countries.
