Despite its growing significance, the legal scrutiny of RTAs remains an underdeveloped academic field. This book considers how the interplay between multilateral and preferential liberalisation of trade in services increasingly raises concerns, both from the perspective of the beneficiaries of such liberalisation and that of regulators. With the application of a thorough article-by-article analysis, the author shows how these concerns lead to vast underutilisation of, and often prejudice against, the benefits of services liberalisation. The book meticulously analyses and compares the EU’s obligations under the GATS and the services chapters of several RTAs to finally assess the merits of the various concerns. This book will be an invaluable resource for students and scholars of law and related subjects. It will also be of interest to government officials looking for a detailed analysis of the topic, and practitioners looking for a framework for analysing RTA provisions.
