Nerina Boschiero is Professor of International Law. She has been the Dean of Faculty of Law at the University of Milan (2014-2021), where she teaches International Law, Private International Law and International Sustainable Development Law. She activated a new international programme (LLM in Sustainable Development) entirely taught in English, and a new PHD (truly international) on Law, Ethics, and Economics on Sustainability

It is with great pleasure that I sign this endorsement of mine to the very fine volume of professor Nerina Boschiero of the University of Milan, Italy, Law School, on "US Trade Policy, China and the WTO".This is not only an excellent, well researched and balanced work, it is also a very timely volume. In the wake of the Covid-19 pandemic, and against the background of the uncertainty surrounding the future of the WTO, a legal analysis of the US trade policies straddling over the last two administrations, and their implications on the lasting trade tensions among major economic powers, is more salient than ever. The WTO cannot flourish without the active participation and support of countries such as the USA and China, but the same States cannot thrive by pursuing unilateral trade policies. This well-crafted book puts the spotlight on distinct topics such as the recent US measures against China under US Sections 232 and 301; the relationships between the Trump and Biden administrations’ trade policies with the ongoing crisis of the WTO dispute settlement system; the very nature of the security exception provision under GATT Article XXI. The rigor of the legal analysis proposed is admirable, especially when one considers that the book was conceived and finalized over years of dramatic changes in international relations. Professor Boschiero’ s outstanding and comprehensive book will be of interest to a broad audience, including international law scholars, practitioners, postgraduate students, as well as domestic civil servants (attached e.g., to national foreign ministries or trade departments); civil servants of international or regional organizations (e.g., at the level of the WTO, or the EU); and NGO experts (especially those focusing on trade implications on human rights).Sincerely Emeritus Professor Giorgio SacerdotiProfessor of International lawFormer Chairman of the Appellate BodyDuring the last six years a revolution has occurred in international trade politics and law. The United States is at the center, especially concerning US relations with China. COVID19 has also complicated matters as has the war in Ukraine. Professor Boschiero, courageously in my view, has written a manuscript that details this revolution in trade law and globalization. She gives a first view of these developments. No other author to my knowledge has attempted to relate this story. Professor Boschiero in her manuscript both recounts the great changes of the past six years, she also analyzes these developments with a critical eye. Her book is a valuable piece of work that should appeal to a broad audience, which includes everyone interested in international trade and globalization.Thomas J. Schoenbaum, University of Washington School of Law
