This paper presents some key components of capacity building in global health diplomacy, as developed by the Global Health Programme and identifies some of the lessons learned. The Global Health Programme at the Graduate Institute, Geneva has pioneered capacity building initiatives in Global Health Diplomacy since it held its first course in Geneva in 2007. It is involved in creating and conducting such executive training outside Europe in order to appropriately reflect the global nature of this course. New approaches and methodologies for capacity development and concrete examples of models applied to executive education are considered. This includes an analysis of what works best in terms of partnering, mainstreaming and development of teaching materials. The aim is to share experiences on innovation in capacity building and executive education. Each section outlines a specific topic related to training in this domain, and concludes with several lessons learned.
