Two African countries, Rwanda and the Democratic Republic of the Congo, have once again reached an agreement in the United States, bringing an end to decades of conflict. Following talks between the two nations held in the U.S. on Friday, the possibility of America signing a mineral agreement with both countries has become strong. This agreement is expected to help establish peace by ending years of military activity in the Democratic Republic of the Congo.

“Today marks the end of violence and destruction. A new chapter of hope and opportunity has begun for the entire region,” said U.S. President Donald Trump.

The agreement was made in the presence of Rwandan and Congolese officials, as well as U.S. Vice President J.D. Vance and Secretary of State Mark Rubio.

After African officials signed the deal, Trump also signed it, describing the agreement as a tremendous success. The foreign ministers of all three countries have signed the agreement.

The Congolese president’s office issued a statement on Friday, describing this as the most significant diplomatic success in 30 years. Following the agreement, DRC President Félix Tshisekedi and Rwandan President Paul Kagame are expected to visit the United States soon — possibly together.

Qatar played a major role in mediating between the two countries. Earlier this year, Qatar took the initiative and also facilitated communication with the U.S.

Violence in the DRC escalated this year after M23 rebels captured several major cities. During their offensive — which included taking control of the provincial capital, Goma — thousands of people were killed and hundreds of thousands displaced.
