Look closely at the map of eastern Democratic Republic of Congo this month and you will see something unusual: the M23 flag has come down from a strip of territory it raised it on only months ago. The Rwandan-backed rebel movement has withdrawn unilaterally from the Ruzizi Plain, the corridor stretching from the southern shore of Lake Kivu down toward the Burundi-DRC border. The gains were the residue of M23’s late-2025 offensive that captured Uvira, a port town that controls the lake’s southern entry point. Now Uvira’s outskirts are emptier, and the movement’s spokesmen are framing the withdrawal as a goodwill gesture.
It is not.
A goodwill gesture, by definition, costs the party offering it something. M23 has demonstrated repeatedly over the last 18 months that it can take territory it could not hold administratively, then trade it back in exchange for diplomatic concessions. The withdrawal from Ruzizi is consistent with that pattern. The movement, and Kigali behind it, are likely calculating that handing back uncontroversial territory now will improve their bargaining position in the next round of Luanda or Nairobi-track negotiations, while preserving the gains in North Kivu around Goma where the real economic and political prizes sit.
The withdrawal also follows an unwelcome diplomatic development for Rwanda. The United States Treasury Department sanctioned elements of the Rwanda Defence Force last month over their role in the eastern Congo conflict — a sanction that bites Kigali precisely because Rwanda has spent two decades cultivating Washington as the indispensable strategic partner that protects it from the awkward questions Europe occasionally asks. Pulling back from Ruzizi is, in part, an attempt to demonstrate that Kigali is responsive to international pressure when properly applied.
Underneath the geopolitical chess, the human story is unforgiving. Human Rights Watch has documented evidence of summary executions of 53 civilians — 46 men, one woman and five boys — during door-to-door raids in Uvira’s neighbourhoods after M23 captured the town in December. That documentation will not disappear because M23 has now moved its troops elsewhere. The families of those killed do not feel safer because the front line shifted. The 4.6 million internally displaced people in eastern DRC — one of the largest displacement populations on earth — will not be returning home on the basis of a tactical withdrawal that leaves both the underlying alliance system and the underlying grievances intact.
There are three structural reasons to be sceptical of a durable peace. First, there is no functioning ceasefire mechanism in eastern DRC. The various process tracks — Luanda, Nairobi, Doha — have produced communiqués and aspirations but no verification arrangement that the parties trust. Without verification, withdrawal can be reversed within 72 hours. Second, the Congolese state’s leverage is severely diminished. President Félix Tshisekedi’s government has, in the search for security partners, traded mineral access to the United States and is reportedly exploring similar arrangements with other extra-regional actors. That dependence reduces the government’s room to drive a harder bargain. Third, the regional military architecture remains scrambled. The Southern African Development Community Mission in DRC, SAMIDRC, ended its deployment in 2025 after suffering significant casualties. The East African Community Regional Force was withdrawn earlier. The African Union has not produced a credible follow-on framework. That vacuum is what M23 has been exploiting.
For Kenya, the eastern Congo story is closer to home than is sometimes recognised. Nairobi was the host of the EAC-led Nairobi process and continues to be a preferred mediation venue. President Tshisekedi has invested significant political capital in that diplomatic geography. Kenyan businesses — banks, telcos, supermarket chains — are increasingly visible in Kinshasa, Goma and Lubumbashi. A failed peace in eastern DRC is bad for Kenyan exports, bad for the EAC’s credibility as a security actor, and bad for the broader narrative that East African capitals can solve East African problems.
The transactional turn in US-Africa policy adds a further complication. Washington’s willingness to swap diplomatic protection for mineral access has changed the incentive structure for both Kigali and Kinshasa. Rwanda now has reason to perform compliance while it negotiates a softer sanctions regime. The DRC has reason to accept whatever security guarantees come bundled with extractive concessions. Neither incentive is aligned with the patient, intrusive monitoring that a real ceasefire would require.
What to watch next is whether Kinshasa, under pressure from civil society and the Catholic Church’s quietly persistent peace mediation, demands a formal verification mechanism as a condition for further negotiations. If it does not, the M23 withdrawal from Ruzizi will be remembered as one more flag-changing exercise in a war that the international system has decided to manage rather than end.
