Policy processes sans frontières: interactions in transnational governance of global health

National policy on global health (NPGH) arenas are multisectoral governing arrangements for cooperation between health, development, and foreign affairs sectors in government policy for global health governance. To explore the relationship between national and global processes for governing global health, this paper asks: in what forms of interaction between NPGH arenas and global health governance are learning and networking processes present? In a multiple case study of Norwegian and Swiss NPGH arenas, we collected data on intersectoral policy processes from semi-structured interviews with 33 informants in 2014-2015. Adapting Real-Dato’s framework, we analyzed each case separately, producing monographs for comparing NPGH arenas. Analyzing both NPGH arenas for relational structures linking external resources to internal policy arena processes, we found five zones of interactions - including institutions, transgovernmental clubs, and connective forms. These interactions circulate ideas and soften arenas’ boundaries. We argue that NPGH is characteristic of transnational governance of global health.
