Mercosur and Post‐Neoliberal Regionalism: Brazil, Argentina, Venezuela, and the Challenges of Relaunching the Bloc

ABSTRACT This article examines the redefinition of the Common Southern Market during the rise of Latin America's pink tide, focusing on how debates over Venezuela's accession intersect with the broader context of post‐neoliberal regionalism. Drawing on literature reviews and primary sources, the study highlights the differing approaches of Brazil, Venezuela, and Argentina to reshaping Latin American regionalism. These divergent strategies influenced Mercosur's institutional reforms and underscored the challenges of reconciling key differences among leftist governments regarding broader regional objectives. Ultimately, the article concludes that conflicts surrounding Venezuela's entry were pivotal in determining Mercosur's trajectory, revealing both the potential and the limits of post‐neoliberal integration at that time.
