The long-promised trip to the continent will see Biden tout American investment in Angola and visit a slavery museum.

Joe Biden is using the first visit to Angola by a U.S. president to promote Washington’s investments in the sub-Sahara African nation and to see a slavery museum where he’ll acknowledge the trafficking of human beings that once linked the nations’ economies.

US President Joe Biden is in Angola on Tuesday for the first and only visit to sub-Saharan Africa of his presidency, which is focused on a major infrastructure project that is a counterpoint to China's investments.
