US President Barack Obama said US companies have pledged $14bn (£8.3bn) of investment in Africa in areas such as energy and infrastructure.
The announcement came at the first US-Africa Leaders Summit, attended by over 40 African heads of state.
The summit is an effort to strengthen US ties with Africa as China increases its African investments.
Mr Obama will also host a dinner for African leaders at the White House in Washington this evening.
