Official corruption is frequently associated with the abundance of valuable extractive resources. This article reviews the worst cases of 'resource curse' in Africa—Angola, Republic of Congo, Democratic Republic of Congo, Equatorial Guinea, Gabon, and Nigeria—in light of the most recent developments. Despite its systematic association with public corruption, however, mineral wealth is neither a necessary nor a sufficient condition. Corruption is widespread in resource-poor countries as well—in Africa and elsewhere—and some resource-rich African countries such as Botswana have a record of good economic performance and high public integrity, suggesting specific ways in which transparency and accountability for the use of mineral resources can be encouraged and corruption correspondingly reduced. Because corruption in resource-rich African countries is heavily influenced by external interests, particularly the multinational extractive industries, recent initiatives by the United States and the international community to foster transparency carry a significant potential for reducing corruption and improving governance.
