The past decade has seen an increase in the scope of relationships, both political and economic, between Africa and the United States. These vary with the complexion of the government in power, though some would say that this was more in emphasis than in substance, others definitely not. It is felt by many Africans, nevertheless, that the Carter Administration's emphasis on human rights has now been downgraded by the present Reagan Administration and that, instead, the geopolitics of U.S.–U.S.S.R. rivalry, and the economic importance of developing the private sector at the expense of bilateral or multilateral aid, have been moved to the fore.
