In Asian countries there is often a gap between rapid economic growth and the development of welfare policies.Moreover, political systems are not always democratic. In order for disabled people in Asia to form disabled people’s organizations (DPOs) and participate in policymaking, it will no doubt be necessary to establish special conditions, while referring to the experience of Western countries. I begin the article by outlining the strong Japanese and Korean disabled citizens’ movements and their influence on policymaking. Then, I study the process of formulating policies for the disabled and the advocacy of DPOs in Vietnam. I suggest that the experiences of these countries have shown the importance of networking with no differentiation according to type of disability, as well as the importance of strategies devised with the political situation in mind. In particular, making the most of the pressure for international cooperation through measures such as the ratification of the United Nations Convention on the Rights of Persons with Disabilities is necessary for reforming the welfare systems and enabling networking among DPOs. The case study of Vietnam also reveals a need for collaboration between domestic DPOs and overseas NGOs, based on the relevant domestic political systems.障害のある人々の当事者団体がアドボカシー活動を通して福祉政策形成に参加する仕組みが根づいている欧米に対して、政治風土の異なるアジアについて、いち早く福祉国家化した日本とそれに続く韓国、さらに近年、急速に経済発展し社会主義国でありつつ欧米のDPO・NGO の政策策定支援を受け入れつつ福祉政策を整備するベトナムを取り上げ、当事者参加の条件を検討した。その結果、障害種別を超えたネットワーク形成で発言力を高めるという欧米との共通点に加え、政治状況に柔軟に対応する戦略と、国連障害者権利条約の批准という国際的な潮流と国内外のネットワークの効果的な活用、さらにベトナムに関する検討からは、社会主義体制と開発援助の枠組みをふまえた戦略の重要性を確認した。また社会体制は異なりつつ共通する、障害のある人のケア責任を家族に負わせる福祉システムの変革の必要性を示唆した
