President Obama will soon be visiting three of those countries: Senegal, South Africa, and Tanzania, and will be changing the agenda as he travels. The necessity of development aid has not disappeared, but President Obama will be shifting the attention to trade and investment. "Trade Not Aid" has been the mantra of the Fair Trade movement, and clearly the rules of the world trading regimes need to change.
Much of the media attention to the trip is --as always -- on its cost. Part of that cost, however, stems from the inclusion of 500 business people in the president's entourage. Presumably, some of them will be covering their own expenses. As reported on NPR, this first serious trade mission to the continent is partly in response to China's growing commitment there.
