The signing of a peace agreement between the governments of the Democratic Republic of Congo and Rwanda in Washington has elicited mixed reactions, with the former Congolese president, Joseph Kabila, describing it as "nothing more than a trade agreement".

The agreement marks a breakthrough in talks and intends to attract billions of dollars of Western investment to a region rich in cobalt, copper, lithium and other minerals.

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.
