This project aimed to increase the capacity of civil society organizations (CSOs), most-at-risk populations (MARPs), and people living with HIV (PLHIV) to deliver effective and efficient HIV services and engage in programming, decision-making, and policy advocacy efforts in the response to the HIV epidemic. The project helped CSOs contribute to the Government of Vietnam's (GVN's) National Strategic Plan for HIV/AIDS. The goal of this five-year project was to develop an empowered, effective, and efficient civil society that is providing a sustainable and significant impact, is accountable to its constituency, is engaged and valued by government programs, and is contributing to the national HIV/AIDS response.
