The EU has as its legal mission to be a good global governance actor yet is continuously challenged in the world. As a global actor, the EU is both a weak and strong actor in a divergent range of global governance areas. EU international relations constitutes arguably a booming field of law where the EU appears often to be a victim of its own success. The book unpacks and problematises the mission of the EU to be a good global actor, while exploring the complexities of fulfilling it. With a focus on the nexus between trade and values, and the role of institutional actors and competing powers, the book advances a future research agenda in the new era of deeper enforcement of EU trade law, EU digital sovereignty and EU defensive multilateralism.
