All states are challenged by the need to protect national security while maintaining the rule of law, but the issue is particularly complex in the China-Hong Kong context.This timely and important book explores how China conceives of its national security and the position of Hong Kong. It considers the risks of introducing national security legislation in Hong Kong, and Hong Kong's sources of resilience against encroachments on its rule of law that may come under the guise of national security. It points to what may be needed to maintain Hong Kong's rule of law once China's 50-year commitment to its autonomy ends in 2047.The contributors to this book include world-renowned scholars in comparative public law and national security law. The collection covers a variety of disciplines and jurisdictions, and both scholarly and practical perspectives to present a forward-looking analysis on the rule of law in Hong Kong. It illustrates how Hong Kong may succeed in resisting pressure to advance China's security interests through repressive law. Given China's growing international stature, the book's reflections on China's approach to security have much to tell us about its potential impact on the global political, security, and economic order.
