Book excerpt: As Asia increases in economic and geopolitical significance, it is necessary to better understand the region’s intelligence cultures. The Handbook of Asian Intelligence Cultures explores the historical and contemporary influences that have shaped Asian intelligence cultures as well as the impact intelligence service have had on domestic and foreign affairs. In examining thirty Asian countries, it considers the roles, practices, norms and oversight of Asia’s intelligence services, including the ends to which intelligence tools are applied. The book argues that there is no archetype of Asian intelligence culture due to the diversity of history, government type and society found in Asia. Rather, it demonstrates how Asian nations’ histories, cultures and governments play vital roles in intelligence cultures. This book is a valuable study for scholars of intelligence and security services in Asia, shedding light on understudied countries and identifying opportunities for future scholarship.
