Juxtaposing perspectives, this insightful book brings together the various dimensions of the relationship between EU law and international law. As the multifaceted interplay between these two legal orders has become increasingly complex with expanding EU policy areas and the development of the EU as a global (normative) actor, this book offers a timely and state-of-the-art contribution to this important field of study.Adopting perspectives from both inside and outside the EU, chapters use international law as a starting point to see how it plays out in the context of EU law as well as vice versa. This work not only reveals the differences between these two legal orders, but also highlights that the EU (and its legal system) is not isolated from international law and follows these rules in its external relations. Wearing the lenses of both international and EU law, it considers the EU and its legal order from an international community viewpoint and assesses the reception and role of EU law in international law.Interactions Between EU Law and International Law presents a unique academic appraisal of the multi-layered interconnections between EU law and international law and provides an invaluable resource for scholars and students of public international law, EU law, international politics and European politics and policy. Its nuanced insights and accessible style will also benefit legal practitioners, policymakers, diplomats and legal advisors dealing with the EU and its Member States – both within the EU and beyond.
