During its history of integration, the EU has developed as a major reference point for regionalisms around the globe. The aim of this research area is to explore how and under what conditions European policies and institutions diffuse to other regions of the world, particularly to Latin America, Africa, the Middle East, and Asia. How are they adapted, translated, or “localized” in different regional and cultural contexts – and when do they meet rejection and resistance? What explains the variations in outcomes as regards institutional designs, meanings and interpretations? Moreover, despite its transformative power beyond its borders, the EU is not the only game in town when it comes to the spread of regionalism across the globe. Which alternative ideas of regional cooperation exist and how do they compete with the EU script? Lastly, can the EU maintain its image as a role model for regional integration in times of financial and economic crises?
