This volume discusses digital diplomacy and artificial intelligence within the context of global governance and international security. Rapid digitalization has changed the way international actors interact, offering new opportunities for international and bilateral cooperation and reinforcing the role of the emergent actors within global governance. New phenomena linked to digitalization and artificial intelligence are emerging and this volume brings a multidisciplinary, mixed-methods approach to studying them.  Written by globally recognized experts, each chapter presents a case study covering an emerging topic such as: international regulation of the web and digital diplomacy, the interplay of artificial intelligence and cyber diplomacy, social media and artificial intelligence as tools for digital diplomacy, the malicious use of artificial intelligence, cyber security, and data sovereignty. Incorporating both theory and practice, quantitative and qualitativeanalysis, this volume will be of interest to graduate students and researchers in international relations, diplomacy, security studies, and artificial intelligence, as well as diplomats and policymakers looking to understand the implications of digitalization and artificial intelligence in their fields.
