The topic of this book is the external action of the EU within international economic law, with a special focus on investment law. The aim of the volume is to provide the reader with an appraisal of the most recent trends and developments that have characterised a field that has been rapidly evolving and in which the EU has imposed itself as a leading actor. The book is aimed at academics, practitioners and graduate students as well as at EU officials and judges, all of whom should find the subject matter discussed useful for keeping updated on a scholarly discussion of relevance to case law.
