"The objective of this article is to analyze the new cooperation of the European Union, in particular with middle and upper-middle-income countries, in order to understand the development policy of the Union in view of the new global scenario, taking into account the new status that these countries have acquired and the implications of this entails in international cooperation processes. This leads us to delve into how the EU cooperates with the middle-income countries and more advanced developing countries. The contribution of this work addresses some of the challenges and perspectives that are currently being planned about the EU’s development policy, providing different elements of analysis and reflection on its future evolution".
