Private participation in infrastructurehas taken two distinct forms in the developing world. Thefirst model, applied primarily in Latin America, focuses onprivatization of existing infrastructure assets. The second,applied largely in East Asia, focuses on retaining existingassets in the public sector but seeking private sectorinvolvement to augment capacity through new greenfieldinvestments. The financial crisis that emerged in East Asiain mid-1997 threatened to undermine much of the progress theregion had made in applying this second model to mobilizeprivate investment and financing for infrastructure. Thisreport describes the background of the 1997 financial crisisin East Asia and its impact on private investment in theregion's infrastructure. It then analyzes lessonslearned in the aftermath of the crisis in sixcountries--Indonesia, Malaysia, the Philippines, theRepublic of Korea, Thailand, and Vietnam--and explores howthese countries can respond to the new challenges.
