The Routledge Handbook of Soft Power (2nd Edition) offers a comprehensive, detailed, and ground-breaking examination of soft power – a key factor in cultural diplomacy, cultural relations, and public diplomacy. Interrogating soft power as influence, the handbook examines manifestations in media, public mind, policy, and theory – in a fraught geopolitical climate, one demanding reconceptualization of soft power’s role in state and civic society behaviour. Part I provides important new conceptualization and critical analysis of soft power from international relations, philosophical, and other social theoretical perspectives; analyses multiple methods of soft power measurement and makes proposals; and connects soft power innovatively with other concepts Part II addresses soft power and contemporary issues by examining new technology and soft power intentions, soft power and states’ performance during the global pandemic, and soft power and values Part III investigates cases from China, France, Greece, Israel, Japan, Kazhakstan, Poland, Russia, South Korea, Spain, Türkiye, and the United States – some in combination. This innovative handbook is a definitive resource for inquirers into soft power desiring to familiarize themselves with cutting-edge debates and research. It will be of interest and value to students, researchers, and policy makers working in cultural relations, international communication, international relations, public diplomacy, and contiguous fields.
