This paper analyses regionalism in Latin America and the Caribbean and interregionalism between this region and the European Union. The complexities and overlapping of Latin American regionalisms are reflected in the several interregional mechanisms that the European Union has with Latin American and Caribbean countries and regional organisations. The paper argues that different political and economic interests in Latin America and the Caribbean have given rise to overlapping regionalist projects, where the overlapping of competences is more problematic than that of membership. Also, Latin American and Caribbean regionalisms have constantly evolved in terms of strategies and organisations. This has generated a number of interregional institutionalized mechanisms between the EU and Latin America and the Caribbean, but the current structure seems in need for reform.
