"Mega-FTA is where international economics meets international politics. It is arguably the most advanced form of regional trade liberalisation while offering great powers a seemingly economic instrument to compete against one another for global preeminence in the geopolitical sense. Xianbai offers an authoritative and innovative account of the drivers behind the formation of mega-scale trade treaties since the 2010s. This volume is a must-read for anyone interested in understanding mega-regionalism in the context of great-power competition."---Di Dongsheng, Associate Dean, School of International Studies, Renmin University of China. “Ji Xianbai’s study of the factors driving mega-regionalism is comprehensive and innovative. He illustrates with great conceptual clarity one of the most important features driving competition and uncertainty in an increasingly rivalrous world. With many of the (geo)political processes affecting the latest phase of globalization remaining in their infancy, and with the overlapping character of normative and regulatory contestation becoming ever more manifest, this book will be useful to scholars and practitioners alike for years to come."---Zachary Paikin, Senior Visiting Fellow, Global Policy Institute (London)"Mega-regionalism is a new trend of economic integration in the globalized world. This book examines this topical issue from a geopolitical and geo-economic perspective. It offers an excellent and empirically-rich explanation of why governments enter mega-regional trade agreements, with a particular focus on the US, China, and the EU. It surely represents an important contribution to the field of international political economy in the era of Sino-US competition and confrontation."---Chia-yi Lee, Associate Professor, Department of Diplomacy, National Chengchi University
