Due to pandemic security measures, the U.S. Secretary of State will hold videoconferences with Nigerian President Muhammadu Buhari and Kenyan President Uhuru Kenyatta. Antony Blinken will also take a virtual tour of several sites, including a field hospital and the U.S.-backed Kenya Renewable Energy Corporation. Robert Godec, head of U.S. diplomacy for Africa, said the initiative is part of a U.S. policy of "re-engagement" with "its African partners. Health permitting, Mr. Blinken is expected to visit Africa in person. Goldacre said Kenya and Nigeria have been identified as "strategic partners" of the United States. He explained, "We work with them on security, economic and trade development, investment and other regional issues." Kenya specifically announced in March its intention to permanently close two refugee camps, Kakuma and Dadaab, where more than 400,000 refugees usually come from South Sudan or Somalia. Robert Godec said the U.S. was "very concerned" about the measure and encouraged Kenya to work with the U.N. agency responsible for refugees (UNHCR). In a virtual address to African heads of state before the 34th African Union Summit in February, Biden promised a stronger partnership with Africa, especially in the fight against the pandemic. This is a major reversal of the policy of his predecessor, Donald Trump, who had been the only sole U.S. president not to visit Africa during his time in office.
