IHP is the co-ordinator and secretariat for the Asia-Pacific NHA Network (APNHAN). APNHAN was established in 1998 by a group of NHA experts in eight Asian countries to provide a mechanism to share technical experience and information to support strengthening of NHA capacity in Asian countries. Since then the network has expanded its coverage to more than 20 countries in the region, as well as the scope of its activities. As part of APNHAN, IHP provides secretariat services, and is actively involved in several activities including coordination of regional HA data collection efforts, organisation of the network�s annual experts meetings, and other research projects.
