The announcement will occur at the U.S.-Africa Business Forum, part of a three-day Africa summit in Washington meant to showcase American interest in improving trade and investment in the region. The forum brings together African heads of state and American business leaders to find ways to boost economic ties. It comes on the second day of a U.S.-Africa summit involving nearly 50 African heads of state. "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. Obama will take part in a discussion with corporate chief executives and government leaders at the event on Wednesday, which will be attended by Commerce Secretary Penny Pritzker, former New York Mayor Michael Bloomberg, and former President Bill Clinton. The business forum will allow dozens of African heads of state to mingle with U.S. and African executives, the official said. It will focus broadly on investment in finance, infrastructure, energy, agriculture and consumer goods. More than 90 U.S. companies are slated to participate including Chevron Corp., Citigroup Inc., Ford Motor Co., General Electric Co., IBM, Lockheed Martin Corp., Marriott International Inc., Morgan Stanley and Wal-Mart Stores Inc. Several African companies were also expected to attend.
In a brief preview of Obama's remarks, the White House did not give specifics on the nature of the business deals or identify which companies were involved.
"These agreements represent conclusive evidence that America is open for more business with Africa as the continent's economic ascent is just beginning,'' Pritzker said in a statement.
"Each day, 250,000 Americans go to work in jobs supported by exports to Africa and these deals will lead to increased prosperity on both sides of the Atlantic in the months ahead,'' she said.
The Obama administration has billed the summit as the first of its kind, but it comes long after Africa gatherings hosted in recent years by China, India, Japan and Europe, suggesting the United States is largely playing a game of catch-up for access to a market in several growing industries.
The U.S.-African Leaders summit opened on Monday with forums touching on a range of issues, including regional security, health, the environment and corruption.
U.S. Vice President Joe Biden speaking on Monday said the African continent has some of the world's fastest growing economies, and that those countries will help shape future developments in the world.
"We're on the cusp where the continent of Africa establishes itself as among the ranks of the world's most prosperous economic and free nations," Biden said.
"In your hands, with your help, Africa can and will go so much further. You're the fastest growing economies in the world, and quite frankly the success of the rest of the world depends in part on your success," he added.
Later Tuesday, Obama is hosting dinner at the White House for the African leaders.
The White House said singer Lionel Richie will entertain the leaders during the dinner on the South Lawn. For dinner, guests will dine on chilled spiced tomato soup, chopped farm-stand vegetable salad, grilled dry-aged beef and cappuccino fudge cake, according to The Associated Press.
The leaders of Sierra Leone and Liberia canceled their trips to Washington because of the Ebola epidemic facing their countries.
