The Security Council is seeking new ways to stabilise the Democratic Republic of Congo (DRC), with an eye to drawing down the long-running UN peace operation there. In parallel, Congolese President Félix Tshisekedi wants to strike a new security agreement with neighbouring countries to suppress armed groups in the country’s east. Why does it matter? The persistence of over 100 armed groups in the eastern DRC is a threat to both Congolese civilians and regional stability. The country’s neighbours have also often used these militias as proxies to attack one another and control economic resources. What should be done? The Security Council should strengthen the UN mission’s capacity to analyse the armed groups’ political links and resolve local grievances these groups can exploit. The UN should support President Tshisekedi’s regional diplomacy, with an emphasis on political reconciliation and economic integration among the DRC’s neighbours as steps to increase security.
