The unique feature of this book is that it approaches the issue of illegal immigration as an unconscious crisis. Accordingly, it holds substantial value in terms of exploring the theoretical basis of and governance methods for maintaining national security in the context of globalization, as well as the early warning mechanisms and crisis management in the context of China’s national security. Since China has a long southwest border, the stability and security of border ethnic areas have long played a decisive role in the stability and security of the country as a whole: if the frontiers are stable, the country enjoys enhanced security. Consequently, investigating the governance mechanism for illegal immigrants in the ethnic areas of the southwest border is of considerable practical relevance. This book offers a valuable asset for researchers in related fields and can be used as a reference book for students of national security. It also benefits practitioners in relevant management departments.
