President Barack Obama flies across the Atlantic on Wednesday for a trip that takes him to Senegal, South Africa and Tanzania, his second visit to sub-Saharan Africa since taking office.
The trip aims to bolster investment opportunities for U.S. businesses, address development issues such as food security and health, and promote democracy.
It comes as China aggressively engages the continent. The Asian nation is pouring billions of dollars into Africa, running oil and mining firms, and replaced the United States in 2009 as the largest trading partner.
Obama's predecessor, George W. Bush, will be in Africa at the same time.
Bush has made multiple visits to Africa since leaving office, and will be in Zambia next week, where he's working with his global health initiative to renovate a cervical cancer screening and treatment center.
While the 44th and 43rd president are not scheduled to meet, first lady Michelle Obama and her predecessor, Laura Bush, will attend the African First Ladies Summit in Tanzania on July 2.
Obama's trip is being overshadowed by the declining health of South Africa's revered former president, Nelson Mandela, who is in critical condition at a Pretoria hospital.
Mandela, who emerged from prison after 27 years to lead South Africa out of its dark days of apartheid, is considered the father of modern day South Africa.
Obama will be in Senegal Thursday and Friday. He arrives in South Africa on Saturday, where he will spend the weekend taking part in a host of activities, including meeting with the nation's leaders and visiting Robben Island, where Mandela spent a majority of his prison term.
He will spend Monday and Tuesday in Tanzania, and is expected back in Washington on July 3.
The president made a brief trip to Ghana during his first term in July 2009.
