Résumé : This edited book focuses on the dynamic balance between global cultural diversity and multilateral convergence in relevant policy areas that involve actual and potential policy convergences (and divergences): the environment, trade, peace and security, and human rights. It offers theoretical reflections about the impact of the concept of multiple modernities on new ideas, cultural backgrounds, and/or national or regional particularities. An interdisciplinary team of authors combines comparative policy analysis with theoretical dialogue about the conceptual, institutional, normative, and political dimensions of a new kind of multilateral cooperation. Finally, the book concludes that by stimulating an intercultural dialogue which goes beyond a mere “rational choice” approach, we can foster progress through a better understanding of the opportunities and limitations offered by a pluralist, varied, post-hegemonic, and multilayered form of multilateral cooperation. This book will be of key interest to scholars and students of European/EU studies, economics, human rights, climate change, history, cultural studies, international relations, international political economy, security studies, and international law.
