ABSTRACT
For the last two decades, regional security organisations have contributed to conflict mediation and the development of cooperative forms of interaction between states in Latin America. Since the 1990s, the Organization of American States (OAS) has played an important role in providing and promoting public security goods in Latin America. However, the recent establishment of the Union of South American Nations (UNASUR) appears to represent a challenge to the OAS’s influence in South America, as UNASUR’s security conceptions and practices overlap with those of the OAS. 1 In fact, UNASUR’s member states have created a South American Defense Council (SDC) to develop policies and strategies to enhance regional cooperation on traditional and new security issues.
