Politics of South America

During the first decade of the 21st century, South American governments have drifted to the political left, with socialist leaders being elected in Chile, Uruguay, Brazil, Argentina, Ecuador, Bolivia, Paraguay, Peru and Venezuela. Most South American countries use free market policies, and it is taking an active path toward greater continental integration.

Recently, an intergovernmental entity has been formed which aims to merge the two existing customs unions: Mercosur and the Andean Community, thus forming the third-largest trade bloc in the world.[27]  This new political organization known as Union of South American Nations seeks to establish free movement of people, economic development, a common defense policy and the elimination of tariffs.
