Résumé : The China-EC/EU relationship, started in 1975, is a highly institutionalized, multidimensional and complex, but to some extent controversial international partnership. It is also challenged within the current unstable world.This book addresses the convergences and the differences (ideational, political, institutional and interests-related) between China and the EU by a collective interaction between Chinese and European scholars. Among other things the book assesses sectoral bilateral dialogue and focuses on the interplay between internal complexity and external policies, discusses ideational divergences in international law and rule of law and in many relevant policy fields. Furthermore, it compares sustainable growth policies; explores trade and investment controversies and negotiations, human rights dialogue; and addresses environment and climate change policies.This text will be of key interest to EU studies and politics, China studies and more broadly to area/Asian studies and international relations/global governance.
