The Public-Private Infrastructure Advisory Facility (PPIAF) is a  multidonor technical assistance facility aimed at helping developing  countries improve the quality of their infrastructure through private  sector involvement. Launched in July 1999, PPIAF was developed  at the joint initiative of the governments of Japan and the United  Kingdom, working closely with the World Bank. PPIAF is owned  and directed by participating donors, which include bilateral and  multilateral development agencies and international financial  institutions. PPIAF was built on the World Bank Group’s Infra- structure Action Program and has been designed to reinforce  the actions of all participating donors. PPIAF is governed by a  Program Council comprising representatives of participating donors  and is managed by a small Program Management Unit.

PPIAF pursues its mission through two main mechanisms:

• Channeling technical assistance to governments in developing countries on strategies and measures to tap the full potential of private involvement in infrastructure.
• Identifying, disseminating, and promoting best practices on matters related to private involvement in infrastructure in developing countries.
