Of that total, USD 45 billion will come from the International Development Association, the World Bank fund that provides grants and interest-free loans for the world's poorest countries.
The package will also feature an estimated USD 8 billion in private sector investments from the International Finance Corporation, a private-sector branch of World Bank, and USD 4 billion will come from the International Bank for Reconstruction and Development, the bank's unit for middle-income nations, World Bank president Jim Yong Kim yesterday said in a statement.
"This represents an unprecedented opportunity to change the development trajectory of the countries in the region," Kim said.
"With this commitment, we will work with our clients to substantially expand programs in education, basic health services, clean water and sanitation, agriculture, business climate, infrastructure and institutional reform," he added.
Kim left for Rwanda and Tanzania yesterday in a show of World Bank support for the entire region.
