From Municipalist Activism to Institutional Changes: An Analysis of the Subnational Dimension in Mercosur (1995-2019)

Abstract Mercosur has gone through distinct phases, leading to the articulation between a myriad of sectors, groups, and actors, among which subnational governments stand out. Local governments started this movement in 1995, with the foundation of the Mercosur Cities Network. In 2000, the Specialized Meeting of Municipalities and Intendencies (REMI) was created, replaced in the following years by the Mercosur Advisory Forum of Municipalities, States, Provinces, and Departments (FCCR), known for being the channel for subnational representation in the bloc. Drawing on bibliographic and document analysis, in addition to interviews and questionnaires, this article aims to analyze the internationalization and inclusion of subnational actors in Mercosur, mainly focusing on the changes observed over the years within these three institutions. The first section introduces the literature on paradiplomacy and deals specifically with Mercosur, seeking to verify how the regional agenda has been expanded, despite decision-making processes not being decentralized. The second and third sections analyse the origins of subnational integration through Mercocities alongside the development of REMI and FCCR. Considering the historical and institutional specificities of Mercosur, the research concludes by questioning the assumption of International Relations literature that regional blocs are potential arenas for effective internationalization of subnational governments.
