"President (Jose Eduardo) dos Santos and Angola have provided important leadership and I want to thank you Angola for the leadership and participation... To solve conflicts that have gone on for too long," Kerry said yesterday on arrival in Luanda on the final leg of his African tour.
Kerry and dos Santos are scheduled to hold talks today.
On his first major tour of Africa as secretary of state, Kerry is focusing on some of the continent's most brutal conflicts.
A State department official travelling with Kerry said Angola has been playing an "extraordinarily positive role" in attempts to solve several regional conflicts, particularly in the Democratic Republic of Congo (DRC) and in Central African Republic.
