The end of the Cold War brought far-reaching world changes in many areas, including the health field. A number of “new” terms emerged (such as global health, global governance, and global health governance or global governance for health), among them global health diplomacy (or health diplomacy). There is no single, consensual definition of this term, and still less are there theoretical and analytical frameworks or empirical data to help understand its meaning and practice more clearly. Global health diplomacy is a sociopolitical practice involving the global health policy community, which promotes the interrelationship between health and foreign policy both at the national level, through cooperation projects or international actions and, in international arenas, by acting in global political space in the widest range of spheres, whether health-sector-related or otherwise.
