Following the publication of Negotiating and Navigating Global Health: Case Studies in Global Health Diplomacy edited by Ellen Rosskam and Ilona Kickbusch, this second volume of case studies will complement the first volume and extends its scope. The new book focuses on health diplomacy negotiations, in Geneva and elsewhere, that have involved WHO or that have substantial implications for the work of WHO. Each of the chapters provides a detailed account of a particular example of global health negotiation, concerning hard and soft law instruments but also addressing the full range of health issues - reaching from issues of research and development, polio eradication, NCDs and plain packaging, to the post-2015 process, the WHO reform and non-state involvement. The book therefore captures a wide-range of experiences of distinguished diplomats, academics and senior practitioners.The contributions to the book are written by negotiators and academics and thus, will provide a unique angle and a tool of reflection for a broad audience. In particular, it will be of interest not only to the academic community and students, but also to policy-makers and diplomats. The case studies will allow for learning on how negotiations work in a complex policy environment. The focus on WHO will explore how a major international organization engages in global health diplomacy and on the implications that health-related diplomacy taking place in a variety of settings has for its work. As such, the book is an important contribution to the growing field of global health diplomacy and to the debate about the role of WHO in the 21str century.
