Trump hosted a UN lunch with a range of leaders from African nations in New York on Wednesday and during a speech went to congratulate them on their economic progress.

The leaders of Ghana, South Africa, Nigeria, Ivory Coast, Ethiopia, Guinea, Senegal, Namibia and Uganda were present at the President's lunch during the annual UN General Assembly session.
In a relatively brief speech, Trump also told African leaders that too many people are suffering from conflict on their continent and commended the leaders for working with the US to fight terrorist groups on their home soil.
The president also reiterated what he called an "enormous security threat" from North Korea and called on countries to stand together in implementing UN sanctions against the north.
