Earlier he was also Special Representative and Head of the United Nations Mission in Somalia (UNSOM) from 2019 to 2022. In a statement announcing the appointment, the UN SG's office described Swan as an experienced diplomat with a long career in African countries facing complex political and security transitions. Swan takes over from Keita, whose tenure drew criticism over supporting the Congolese army coalition that is accused targeting Congolese Tutsi communities. This is addition to MONUSCO's failure to end insecurity in eastern DR Congo, despite being one of the UN's largest and longest serving mission.

Karega He comes at a time the UN mission has been tasked with monitoring the ceasefire between the Congolese government coalition and the AFC/M23 rebels, who control key cities in eastern DR Congo, including Goma. Crisis observers accused the mission of misreading developments on the ground and providing assessments that influenced decisions within the UN system. Under Keita’s tenure, the mission has also faced increased mistrust from the AFC/M23 movement, which has repeatedly accused its personnel of abandoning neutrality and producing reports it considers biased.

Established in 1999 as MONUC before transitioning into MONUSCO in 2010, the mission remains one of UN’s longest-running and most expensive peacekeeping operations,with more than $25 billion spent in just over two decades. It operates under mandates renewed annually by the UN Security Council, whose permanent members France, China, Russia, United Kingdom, and US hold decisive authority over its direction. Although Kinshasa and the UN agreed in November 2023 on a gradual withdrawal plan for MONUSCO, the mission’s mandate was later extended. Most recently, the Security Council renewed it until December 20, 2026.
