US President Barack Obama has arrived in Dar es Salaam in Tanzania, on the last leg of his African tour.
Mr Obama and his family were welcomed by his Tanzanian counterpart Jakaya Kikwete and troupes of dancers.
The president is being accompanied by hundreds of business executives and trade is expected to top the agenda.
Mr Obama will also visit an US-owned power plant, following his announcement over the weekend of a multi-billion-dollar electricity initiative.
The $7bn (£4.6bn) five-year initiative is intended to double access to electricity in sub-Saharan Africa, in partnership with African countries and the private sector.
Mr Obama made the announcement at South Africa’s University of Cape Town after the US first family had visited Robben Island, the former jail where Nelson Mandela spent 18 years of his 27 years in captivity during his fight against the apartheid regime.
During his time in South Africa, the US leader did not visit Mr Mandela, who remains critically ill in hospital suffering from a lung infection, but he did meet the Mandela family in private.
