Since 2002, the European Union and its member states have pursued an ambitious foreign policy in Latin America, particularly in Chile, through an Association Agreement and various bilateral and regional programs to enhance trade, social cohesion, and environmental sustainability. This chapter aims to analyze the adaptation of public policies from Europe to Chile, focusing on learning processes, best practice experiences, and knowledge sharing. According to Adler and Hass (1992), governments learn from each other through policy learning or by obtaining new ideas and frameworks that are then implemented to change existing policies or create new ones. The importance of these learning processes lies in understanding some critical questions: Which critical junctures can lead to policy learning? Which actors are involved, and what are their demands? This chapter aims to analyze changes in the preferences and interests of governmental and non-governmental actors in Chile and the learning processes that have projected the EU’s influence. Furthermore, this study aims to analyze if these processes have enabled institutional strengthening and the creation of better governance among a diversity of actors from the public and private sectors and citizens, thereby contributing to the regional dimension-building of the EU’s actorness.
