This timely book explores the complexities of the EU's international economic relations in the context of its commitment to the rule of law both within the Union and internationally. It does so from three main standpoints: the 'autonomy' of the EU and judicial dialogue, the rule of law through treaty drafting, and the role of international courts and tribunals in upholding the rule of law. Bringing together diverse perspectives from both EU and international law scholars and practitioners, the book investigates some of the most controversial and lively issues in the field of EU external relations, such as the relationship between EU law and international investment arbitration. The contributions consider how dialogue between EU law and international law can enhance the rule of law, providing an analysis of legal issues that also offers concrete tools for overcoming the challenges that arise from them. Scholars and practitioners working in EU external relations, constitutional EU law, and public international law will find this book to be essential reading. Its critical approach will also be of great interest to policymakers in Europe and beyond.
