This Research Handbook provides a broad yet detailed treatment of international arms control law. It takes stock of existing arms control agreements, addresses current challenges and aims to indicate avenues for the future development of this distinct branch of public international law. Split across nine thematic parts, this comprehensive Handbook goes beyond the pure encyclopaedic approach by providing analytical and doctrinal guidance. Chapters provide extensive analysis of international arms control law, addressing both conventional weapons and new technologies, contextualising arms control law and politics through identifying actors, forums and regulatory approaches. The impressive list of contributors also explore geographical zones of arms control including Africa, Asia, Europe and Latin America. Investigating both complex theoretical and recent practical approaches into arms control law, this Research Handbook will be an ideal read for interested students and academics as well as practitioners involved in conflict, security and international law.
