American organizations

The graphic provides an overview of membership in the most important international organizations on the American continent – and, we believe, with success. But above all: up to date. The graphic shows (from outside to inside)

  • OAS
  • PROSUR (under construction since March 22, 2019)
  • UNASUR (in dissolution)
  • CAN (Andean Community)
  • ALBA

According to AVIATIONOPEDIA.COM, the numbers in brackets after the names or abbreviations of the organizations indicate the number of full members. The meaning of the abbreviations can be found in the table at the bottom of the page. For details on the major American organizations, use the menu on the left.

The above-mentioned American organizations are shown geographically in the graphic opposite. The new organization PROSUR and the disbanding organization UNASUR have not been incorporated.

The Central American Integration System (Sistema de la Integración Centroamericana – SICA), an institutional framework for the regional integration of eight states in Central America including the Dominican Republic in the Caribbean, is not included in either of the graphics on this website.

Recommendation: Print out both the graphics and the table so that you can see these related and complementary parts together.

The organization was founded in March 1991 with the signing of the agreement for the creation of a common market in Latin America by the presidents of four South American states in Asunción.


The goals are free movement of goods and services, common external tariffs and the coordination of economic, monetary and industrial policy.

The Ouro Preto protocol to the Mercosur Treaty of December 1994 gave Mercosur international legal capacity and its own institutions. The small General Secretariat of the Community got its seat in the Uruguayan capital Montevideo.

Mercosur (including Venezuela) had around 300 million inhabitants in 2018 with a GDP of around 3,000 billion US dollars – this corresponds to around 60% of the EU population and 17% of EU GDP.

Still pronounced national competitiveness thinking and severe economic and financial crises make the ambitious goals of Mercosur seem hardly feasible at the moment. The Venezuela crisis from 2016 and the associated changing organizational forms on the South American continent must show whether Mercosur can hold its own against its competitors.
