"The essays presented in this collection not only examine the various most interesting concepts and institutions of the law of treaties under the Vienna Convention and the interplay between these and general international law and highlight the impact that the Vienna Convention has exerted on the development of general international law, but also do so in a thoroughly analytical way. This is a book that will repay reading." --Sienho Yee, Chinese Journal of International Law

"There can be few such compilations of works by so many different contributors that achieve such coherence of subject matter, themes and styles. All in all, it is a very valuable addition to the literature on the law of treaties." --Richard Gardiner, University College London, UK
