President Barack Obama will announce on Tuesday that U.S. businesses have committed to investing $14 billion in construction, clean energy, banking and information technology projects across Africa, a White House official said.

The announcement will occur at the U.S.-Africa Business Forum, part of a three-day Africa summit in Washington meant to showcase U.S. interest in improving trade and investment in the region.

"These investments will deepen U.S. economic engagement in Africa, fueling growth that will support broader African prosperity and emerging markets for U.S. businesses, which will support jobs in both the United States and Africa," the White House official said.
