The HEPVIC project aims to enhance the health policy-making processes in developing countries through a comparative study of three Asian case countries – Vietnam, India and China. Health policy processes in Vietnam is a new subject that not many studies focussed. The study was adopted the qualitative research method: interviews the key respondents with mapping and reviewing documents on the related policy areas. This study aimed to understand the health policy process from the agenda setting, development until its implementation. Moreover, this research will explore the complex interplay between different influences on the policy process, and the complex interplay of four determinants of health policy processes: civil society, human resources, service delivery and the wider health system. Study in Vietnam consists of 3 cases of health polices including law on domestic violence prevention and control, national master plan of safe motherhood and national master plan for youth and adolescence. This abstract will present the key issues for health policy processes from preliminary findings in Vietnam, focussing on the policy process of the law of domestic violence prevention and control including the complex interplay among 4 themes. Finding from this case also was compared with policy on skill birth attendance and policy on adolescent reproductive health. The result can be used as lesson for improved health policy process in the context of Vietnam.
