Multi-Sector collaboration to promote healthy ageing: A comparative case study of national policy responses in the Western Pacific Region

This study investigates how national policies in nine Western Pacific countries-China, Japan, South Korea, Australia, New Zealand, Singapore, Malaysia, Vietnam, and Cambodia-promote healthy ageing through multi-sector collaboration. The objective is to identify common patterns and country-specific features in the governance and organization of collaborative efforts. Using comparative case study analysis based on government documents, official reports, academic literature, and authoritative websites, the analysis reveals a growing policy emphasis on cross-sector collaboration in healthy ageing. Three distinct models of collaborative governance were identified, each characterized by different sectoral roles and coordination mechanisms. These findings contribute to a better understanding of how multi-sector approaches are structured and implemented in diverse policy contexts to support healthy ageing. The study offers practical insights for policymakers aiming to strengthen intersectoral collaboration and align national strategies with international frameworks such as the UN Decade of Healthy Ageing (2021-2030) and the WHO Regional Action Plan for Healthy Ageing in the Western Pacific Region.
