From the reviews:
"This book provides an extensive study of the changes brought about in EU foreign policy by the Lisbon Treaty, analysing the multiple areas of EU external action. ... All the subjects in the book are developed through detailed and comprehensive analysis. ... this book is recommended to those who already have a good knowledge of the subject and seek deeper insight into particular legal, political and economic aspects of EU foreign policy." (Paola Tessari, The International Spectator, Vol. 48 (1), March, 2013)
"The most important feature and added value of the book is likely its interdisciplinary combination of legal and political science approaches, as well as its focus on both the theoretical and practical consequences of the changes introduced by the Treaty of Lisbon. ... its coverage of a wide range of policy areas of external relations, its combination of legal and political science approaches, as well as its look at the practical consequences of the Treaty of Lisbon, makes the book a very valuable contribution." (Tina Van den Sanden, Common Market Law Review, Vol. 50 (4), 2013)
"The book under consideration distinguishes itself from the others that have already been published in that it expressly seeks to examine not only the law but also the policy aspects of the Union's external relations post-Lisbon. Furthermore, this book seeks to examine the full ambit of the Union's external relations and does not deal with only one aspect of it. ... this is a timely, well-informed and interesting contribution to the literature. ... all in all, it is a welcome addition to the literature." (Urfan Khaliq, European Public Law, Vol. 19 (2), 2013)
