This book analyses immigration policies in East Asia in the context of contemporary global migration flows and mobility. To assess how global norms of migration have impacted the East Asian migration region and explore regional migration trends, the book contains 13 case studies which investigate the regulation of immigration in China, Hong Kong, Japan, South Korea, and Taiwan. Three analytical strands, namely norm diffusion, identity politics and citizenship, build the theoretical framework for the case studies which investigate how regional and national norms, discourses and institutions affect local communities and migration patterns. In particular, the book analyses contemporary issues such as immigration policy reforms, practices of inclusion and exclusion in local communities, and discourses on multiculturalism and risk. The book utilizes a comparative perspective which enables readers to reflect on the role of national identity, international organizations and law, public security concerns, and labor market demands in the articulation and implementation of contemporary immigration policy in East Asia. This book substantially complements the existing literature on immigration governance and interregional migration mobility in East Asia and will be of interest to academics in the fields of East Asian studies, Public Policy, Immigration and Migration studies, and Comparative politics.
