Phase I provided emergency support to control HPAI in poultry and respond to the threat of a human pandemic. Phase II supported Vietnam's transition to a sustained response through implementation of activities within the Viet Nam Integrated National Operational Program for Avian and Human Influenza, 2006-2010 (the OPI, also known as the “Green Book”).
The OPI was prepared by a Government taskforce established under the National Steering Committee for Avian Influenza (NSCAI), with support from UN agencies, the World Bank and other donors. It was adopted by the Government on 31 May 20062 as the framework for mobilization of national resources and international support to fight HPAI. It was also broadly endorsed by the international community at a Government-Donor meeting on 2nd June 2006 as a basis for harmonised support following the principles of the Hanoi Core Statement (HCS).
