The United Arab Emirates has officially welcomed the signing of a landmark peace agreement between the Democratic Republic of the Congo (DRC) and Rwanda, describing it as a vital move toward long-term peace and stability across Africa.

It’s one of several attempts to end the deadly conflict in the troubled eastern DRC. Will it work where others failed?

The official signing of the peace agreement took place earlier Friday at the State Department and was witnessed by Secretary of State Marco Rubio and Senior Adviser for Africa Massad Boulos, whom Trump has largely credited with bringing about the deal.
