Venezuela Joins Mercosur, Paraguay Suspended

South America's intergovernmental organizations: Mercosur in green, the Andean Community (CAN) in (orange), and remaining members of UNASUR in blue (claimed territorial extents). Map by Evan Centanni, based on this map by Wikimedia user Luan.

After over six years of waiting, Venezuela today officially joined Mercosur (the "Southern Common Market"), one of South America's two main trade blocs.

The country was previously part of the continent's other major bloc, the Andean Community (CAN), but left that organization last year in anticipation of the switch to Mercosur (see Venezuela Leaves Andean Community).

By the time the Venezuela left CAN last year, its application had finally been approved by all Mercosur member states except for Paraguay; but despite support from that country's president, an opposition party in its congress continued to block Venezuela's entry into the trade organization.
