(CNN) - When President Barack Obama visits Africa next week, his predecessor, George W. Bush, also will be on the continent.
Obama flies Wednesday across the Atlantic for a trip that takes him to Senegal, South Africa and Tanzania, marking his second visit to sub-Saharan Africa as president (He went to Ghana during his first term).
Meanwhile Bush, who's made multiple visits to Africa since leaving office, leaves next week for Zambia, where he's working with his global health initiative to renovate a clinic that will serve as a cervical cancer screening and treatment center, according to the George W. Bush Presidential Center.
While the 44th and 43rd president are not scheduled to meet up, first lady Michelle Obama will attend an event hosted in part by former first lady Laura Bush. The two will attend the African First Ladies Summit, put on by the George W. Bush Institute, in Tanzania on July 2, the final day of the Obamas' trip.
Aid to Africa was a big part of the Bush administration's foreign policy. The former president started the President's Emergency Plan for AIDS Relief, otherwise known as PEPFAR, during his tenure at the White House. Started in 2003, the program grew into a $50 billion program to combat AIDS around the globe through testing, counseling and medical treatment.
The program is widely considered one of Bush's biggest successes. At the April dedication ceremony for the Bush presidential library in Dallas, Obama touched on his predecessor's humanitarian work.
"We remember the compassion that he showed by leading the global fight against HIV/AIDS and malaria, helping to save millions of lives and reminding people in some of the poorest corners of the globe that America cares and that we're here to help," Obama said.
Obama's trip will focus on potential trade and investment opportunities for U.S. businesses; young people and democracy in Africa; and development issues such as food security and health.
