US President Donald Trump is set to host the signing of a peace deal between the Democratic Republic of Congo (DR Congo) and Rwanda in Washington. The agreement aims to end the long-running conflict in the resource-rich eastern DR Congo. Both countries' leaders, President Felix Tshisekedi of DR Congo and President Paul Kagame of Rwanda, will officially endorse the deal. Earlier, foreign ministers of the two nations signed the peace accord in June, which Trump called a "glorious triumph." The region has seen escalating violence. DR Congo's army accused rebel groups backed by Rwanda of trying to "sabotage" the peace process. Meanwhile, the M23 rebel group claimed the DR Congo army broke a ceasefire by launching attacks. Earlier this year, the M23 seized large parts of eastern DR Congo, displacing thousands. The M23 group will not attend the signing as they are in separate peace talks with DR Congo, led by Qatar. Qatar and the US coordinate mediation, with Qatar closer to Rwanda and the US seen as DR Congo's ally. Despite the hopeful event, some experts doubt lasting peace. Bram Verelst from the Institute for Security Studies said, "The signing ceremony is unlikely to alter this situation, though there is some small hope it could increase accountability on Congolese and Rwandan leaders to honour their commitments." Rwanda denies supporting the M23, even though UN experts say Rwanda's army controls M23 operations. The FDLR militia, linked to the 1994 Rwandan genocide, is also a key issue. Rwanda insists on its disarmament, while DR Congo demands Rwandan troop withdrawal. The deal includes both demands. The US is interested in peace because of DR Congo's vast mineral wealth, estimated at $25 trillion. These minerals are vital for electronics, electric cars, and military gear. Trump said the US would gain many mineral rights from Congo through this peace effort. The deal also aims for cooperation on mining, hydropower, and infrastructure. However, DR Congo states it will not move forward until Rwandan troops leave eastern DR Congo. Several African and Arab leaders, including those from Burundi and Qatar, are expected at the signing. The M23 rebels, embroiled in fighting and denied attendance, continue talks with the government separately. This signing is a key step, but challenges remain in achieving durable peace in the troubled region.
