This book makes a new departure from others on the subject. Not only does it analyze Brexit from the domestic point of view in the UK-democracy, social analysis, and construction of new institutionalization with the EU - it extends the analysis externally and reconsiders the EU and UK relationship with Asia and the implications for international relations and a new world order. From this foundation, this book presents a broad and diverse spectrum of views concerning Brexit and the EU. For these reasons, it serves as an original and excellent textbook for undergraduate and graduate students as well as for researchers of the EU and international relations. Contributions to this volume are from the European Union Studies Association (EUSA) Asia Pacific Tokyo Conference and affiliated conferences at the following universities between 2017-19: Aoyama Gakuin University (Tokyo), Taiwan National University (Taipei), and Fudan University (Shanghai). Almost all of the authors have engaged in interdisciplinary research on the EU, are members of the EUSA Asia Pacific, and have made public presentations on Brexit and how it relates to the EU, Asia, international relations, economics, and institutions. Therefore, this book presents various aspects of Brexit and its aftermath from the perspectives of the disciplines of political science, economics, and international relations in its analysis of the UK, the EU, Asia, and the future world order. The EUSA Presidents and executive committee members participated in the Asia Pacific Conference; postgraduate student workshops were organized and their presentations moderated, thereby guaranteeing both the quality of the contributions to this book as well as encouraging young talented scholars to write about Brexit and the EU.While many books on Brexit have been published, this book offers many new and perspectives that provide suggestions for possible solutions to the problems facing the UK andthe EU after Brexit.
