The article analyses Chile's participation in the South American Defense Council (CDS), since its establishment in December, 2008. To such effect, it asserts that its role in said Council represents an important part of the Latin American priority defined in Chilean foreign policy. Moreover, the work argues that, much in the same way as in the participation in other regional integration mechanisms, the country has carried out its activities in the Council with moderation and pragmatism. This suggests that, in addition to its active involvement in the CDS, Chile continues to be strongly committed to the hemispheric framework of security and defense.
