The Western Pacific Regional Office, located in Manila, the Philippines, represents WHO in the Asia Pacific. The office aims to act as the "health conscience of the Region" and operates semi-autonomously with its own regional budget.

The regional office’s role is to act as a catalyst and advocate for action at all levels, from local to global, on health issues of public concern. Working together with a broad spectrum of partners from all sectors of society, WHO in the Western Pacific is involved in a host of closely related public health activities, including research, databanking, evaluation, awareness raising and resource mobilization.

The regional office’s purpose is to lead the regional response to public health issues on all fronts – medical, technical, socio-economic, cultural, legal and political – towards the achievement of WHO’s global health mission.

The WHO’s mission is to support all countries and peoples in their quest to achieve the highest attainable level of health, defined in the WHO Constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."
