This book provides the first systematic analysis of new Asian regionalism as a paradigm shift in international economic law. It argues that new Asian regionalism has emerged amid the Third Regionalism and contributed to the New Regional Economic Order, which reinvigorates the role of developing countries in shaping international trade norms. To substantiate the claims, the book introduces theoretical debates and evaluates major regional economic initiatives and institutions, including the ASEAN+6 framework, APEC, the CPTPP and the RCEP. It also sheds light on legal issues involving the US-China trade war and the COVID-19 pandemic, as well as trade policies of Asian powers, the European Union and the United States. Hence, the legal analysis and case studies offer a fresh perspective of Asian integration and bridge the gap between academia and practice.

'This ground-breaking work by a leading scholar in the field of international economic law provides a critical account of new Asian regionalism. Pasha L. Hsieh persuasively takes on the ambitious task of writing a comprehensive book on the increasingly important role of developing countries in shaping international trade norms. This book will surely prove to soon become an indispensable reference for practitioners and scholars in international law and international relations.'

Julien Chaisse - Professor, City University of Hong Kong & President, Asia-Pacific FDI Network

'Pasha L. Hsieh has written a remarkable book that should well serve all who wish to understand the increasing importance of Asian economies and political systems for international relations, rivalries and cooperation. It is comprehensive, analytical, theoretical and yet practical. It is also full of interesting, updated details, but nevertheless highly readable.'

'The conclusion of the RCEP heralds the emergence of Asia as a new center of the global trading order. This book provides a unique lens through which to view how new Asian regionalism led by ASEAN has transformed international economic law. Pasha L. Hsieh’s extensive research successfully fills a gap in the existing literature on regionalism by combining legal and political perspectives.'

Yuka Fukunaga - Professor, Waseda University

'This is an excellent and very timely contribution on an important area of international economic law. The book by Pasha L. Hsieh comes at a particularly opportune time with the rise of regionalism. It provides a clear, comprehensive, and well-researched analysis of regional trade integration law and policy in Asia. It combines theoretical analysis with a clear exposition of the law and will be of great use both to international trade lawyers and academics at large.'

Rafael Leal-Arcas - Jean Monnet Chair Professor, Queen Mary University of London

'In this compelling monograph, Pasha L. Hsieh convincingly builds upon his previous work theorizing a New Regional Economic Order (NREO) and applying his NREO theory to explain the emergence and importance of new Asian regionalism. Hsieh draws upon his advanced training in law and political science to engage with both legal and international relations literatures, filling in important lacunae in the scholarship of each discipline. This ambitious work is a must-read for any serious scholar of international economic integration in the Asia-Pacific.'
