“The arguments are persuasive and are both legal and philosophical…There is no other book being written to make such strong and clear argument about the problems of IEL before…The book definitely deserves the highest academic recognition from many perspectives.” – Chang-fa Lo,
Asian Journal of WTO and International Health Law and Policy, Volume 8:345
“For his distinct and distinctive reconceptualization of IEL, Petersmann deserves our thanks and praise.” – Gonzalo Villalta Puig,
Leiden Journal of International Law, Volume 26. Issue 04.
“For over three decades, the scholarship of Professor Ernst-Ulrich Petersmann has illuminated trade law for academics, practitioners, and students alike. Writing with intensity, persuasiveness, and enviable productivity, Petersmann has opened more new doors into our thinking about international economic law (IEL)2 than any scholar of his generation…Peterman's new treatise, International Economic Law in the 21st Century, lays out his intellectual edifice in its most comprehensive and inspirational form to date.” – Steve Charnovitz,
Journal of International Economic Law, Vol. 17, no 1
“… Petersmann's recent work is undoubtedly a significant contribution to the indeed indispensable global discourses on the future directions to be taken by the lawmaking as well as law enforcement processes in the international economic system, and it is thus highly recommended to scholars and practitioners interested in this important issue of our time.” – Karsten Nowrot,
European Yearbook of International Economic Law 2014
