The bulk of the commitments came from private-sector companies, including Coca-Cola and General Electric, underscoring Africa's growing appeal to businesses. The continent is home to six of the world's fastest-growing economies and a rapidly expanding middle class with increased spending power.

Yet Obama noted that U.S. trade with the entire African continent is about the same as its trade ties with Brazil and that just about one per cent of U.S. exports go to sub-Saharan Africa.
'We recognize Africa for its greatest resource, which is its people, their talents and their potential.'- U.S. President Barack Obama
"We've got to do better, much better," he said during closing remarks at a daylong session that brought together U.S. and African politicians and business leaders. "I want Africans buying more American products and I want Americans buying more African products."
The U.S. is hardly alone in seeing economic potential in Africa, with China, Europe and India moving aggressively to tap into Africa's growing markets. China in particular is hungry for oil, coal and other resources and is eager to develop the roads, bridges and ports needed to pull them out of Africa.
"We also realize we have some catching up to do," said Michael Bloomberg, the former New York mayor and billionaire businessman who opened the summit Tuesday. "We are letting Europe and China go faster than the U.S."
Obama has sought to cast the U.S. as a better partner for African nations than China, arguing that his administration has a long-term interest in the continent's success and is not simply seeking to extract resources for its own purposes.
"The United States is determined to be a partner in Africa's success," he said. "We don't look to Africa simply for its natural resources. We recognize Africa for its greatest resource, which is its people, their talents and their potential."
The business forum is part of an unprecedented three-day summit underway in Washington, with nearly 50 African heads of state in attendance. Obama was hosting the leaders at a White House dinner Tuesday night.
Major U.S. companies attend summit
About 100 U.S. companies were represented at Tuesday's conference. Vice-President Joe Biden and Secretary of State John Kerry also addressed the attendees, as did former President Bill Clinton, who declared that the U.S. has "only barely scratched the surface" of Africa's economic potential.
In conjunction with the meeting, U.S. companies announced $14 billion in investments for Africa. Among them: a $5 billion investment from Coca-Cola to fund manufacturing lines and production equipment; $2 billion investment from GE by 2018; $200 million in investments across Africa by Marriott, and a $66 million commitment by IBM to provide technology services to Ghana's Fidelity Bank.
The White House also touted another $12 billion in new commitments for Obama's Power Africa initiative from the private sector, World Bank and the government of Sweden. Obama announced the Power Africa initiative last summer, setting a goal of expanding electricity access to at least 20 million new households and commercial entities.
The president said that with the new financial commitments, he was boosting that goal to 60 million homes and businesses.
U.S. Export-Import Bank controversy
Obama also announced $7 billion in new government financing to promote U.S. exports to and investments in Africa. That includes $3 billion in financing from the U.S. Export-Import Bank aimed at supporting American exports to Africa over the next two years.
The zEx-Im Bank is at the centre of a political controversy in Washington, with some Republicans seeking to shutter the bank and threatening to block its re-authorization when Congress returns from recess this fall. The GOP lawmakers seeking to shut down the bank argue that its spending is politically motivated and unnecessary.
GE CEO Jeff Immelt, who was among the business leaders participating in Tuesday's summit, appealed to Congress to renew the bank's charter, saying its existence signals to other countries that the U.S. government believes in investing overseas.
"The fact that we have to sit here and argue for it is just wrong," Immelt said.
Obama also signed an executive order Tuesday creating an advisory committee comprised of private sector representatives who will advise the White House on ways to boost economies ties with Africa.
