President Trump claims credit for the outcome. The main question now is how the treaty will be implemented as fighting still rages in eastern Congo.

Rwanda and the Democratic Republic of Congo have signed a peace deal in Washington aimed at ending decades of devastating conflict between the two neighbours, and potentially granting the US lucrative mineral access. The deal demands the "disengagement, disarmament and conditional integration" of armed groups fighting in eastern DR Congo.

The U.N. accuses Rwanda of supporting rebels who have taken over large swathes of the Democratic Republic of Congo - home to valuable minerals.
