() President Donald Trump is meeting with the leaders of Congo and Rwanda on Friday afternoon following a U.S.-mediated peace deal.

The peace deal, signed earlier Friday, should formally bring an end to decades of deadly fighting in eastern Congo.

As part of the accord, the U.S. government and American companies will have access to minerals within the region.

Trump said at a news conference Friday that he was able to broker a deal for “one of the worst wars anyone’s ever seen.”

“I was able to get them together and sell it,” Trump said. “And not only that, we’re getting for the United States a lot of the mineral rights from the Congo.”

The deal has been touted as an important step toward peace in the Central African nation of Congo, where conflict with more than 100 armed groups, the most potent backed by Rwanda, has killed millions since the 1990s.
