The Democratic Republic of Congo (DRC) and Rwanda have reached an outline economic cooperation accord during their first talks since signing a peace deal, the United States said late Friday.

Neighbours agree on terms of economic cooperation in several areas, including energy and mineral supply chains.

The deal in June between Rwanda and Congo marked a breakthrough in talks held by U.S. President Donald Trump's administration, which aims to bring an end to fighting that has killed thousands and attracted billions of dollars of Western investment to a region rich in tantalum, gold, cobalt, copper, lithium and other minerals.
