Over the past decade, Nairobi has become one of the most active mediation hubs on the African continent. Kenya has played central or supporting roles in peace processes for South Sudan, Somalia, the eastern Democratic Republic of Congo, and most recently Sudan. Kenyan diplomats, former presidents, and senior officials have shuttled between Juba, Mogadishu, Kinshasa, and Khartoum with a regularity that would make any foreign ministry proud. The question worth asking is: why Kenya, and at what cost?
Why Kenya keeps getting called
Kenya's emergence as a regional mediator is not accidental. Several structural factors make Nairobi a credible convener. First, Kenya is perceived — at least relative to its neighbours — as a stable democracy with functional institutions. It has held competitive multiparty elections since 1992, has not experienced military coups, and has a relatively free press. For parties seeking a neutral venue, this matters more than it might seem: neither Addis Ababa nor Kampala carries the same perception of neutrality, and both have had direct security interests in conflicts they might otherwise mediate.
Second, Nairobi has genuine economic ties with most of the conflict-affected states in its region. Kenya is South Sudan's largest trading partner. Kenyan banks, mobile money platforms, and businesses operate across East Africa. This gives Kenya a material stake in regional stability that goes beyond diplomatic ambition — Kenyan businesses lose money when wars disrupt trade routes and cross-border commerce. The Kenyan private sector has, at various points, been an informal lobby for regional peacemaking precisely because instability costs it real money.
Third, Kenya benefits from international support for its mediating role. The United States, the European Union, and the United Nations have all, at various points, channelled mediation efforts through Kenyan-hosted processes or endorsed Kenyan envoys. This external validation reinforces Kenya's credibility while also partially offsetting the diplomatic costs of taking positions on sensitive inter-state disputes.
The South Sudan test case
South Sudan has been Kenya's most consequential and most frustrating mediation challenge. Nairobi hosted the negotiations that produced the 2018 Revitalised Agreement on the Resolution of the Conflict in South Sudan (R-ARCSS), the framework that formally ended — on paper — the five-year civil war between forces loyal to President Salva Kiir and former Vice President Riek Machar. Kenya's then-president Uhuru Kenyatta played a prominent role in bringing the parties together.
The results have been mixed at best. Implementation of the R-ARCSS has been chronically delayed. A unified national army has not materialised. Subnational violence has continued across several states. The transitional government in Juba has repeatedly extended deadlines for elections without consequences. Kenya's leverage, having secured the agreement's signature, has diminished now that the political spotlight has moved on. This is a recurring problem in African mediation: the convener gets credit for the agreement, but the mechanisms for enforcing implementation are weak, and the mediator has limited tools for holding parties to commitments once the cameras have left.
Somalia: a longer and more complex engagement
Kenya's relationship with Somalia is simultaneously its most important regional security relationship and its most complicated. Kenya hosts hundreds of thousands of Somali refugees; Kenyan troops form a significant part of the African Union mission in Somalia (ATMIS); and Kenyan territory has been repeatedly targeted by Al-Shabaab in retaliation for that military presence — most notably in the 2013 Westgate shopping centre attack and the 2019 DusitD2 complex attack in Nairobi, which killed dozens.
This means Kenya's engagement with Somalia is not purely diplomatic — it carries a direct security cost. The decision to send Kenyan Defence Forces into Somalia in 2011 and to sustain that presence since was strategic: Kenya calculated that containing Al-Shabaab inside Somalia's borders was preferable to allowing the group to expand its operational reach. That calculation has proven broadly correct, but at significant cost in Kenyan lives, political capital, and public tolerance for the mission.
Kenya's mediation role in Somalia's political process has also run into tensions with Mogadishu. Somalia accused Kenya of backing regional leaders in Jubaland who were at odds with the federal government, and the two countries briefly severed diplomatic relations in 2020. The episode illustrated a fundamental tension in Kenya's regional posture: it wants to be seen as a neutral mediator, but it also has specific strategic interests in how Somalia is governed. Those two things are difficult to reconcile.
The limits of a middle power
Kenya is not a great power. It does not have the economic resources to underwrite peace deals, the military capacity to enforce them, or the international influence to bring major external actors into alignment behind a unified framework. What it has is credibility, geography, and institutional relationships. These are real assets, but they have limits.
The Sudan conflict — where Kenya has participated in AU-led mediation efforts — illustrates those limits sharply. The key external actors with genuine leverage over the SAF and RSF are Egypt, Saudi Arabia, the UAE, and to some extent the United States. Kenya can host talks, provide logistical support, and lend its diplomatic voice, but it cannot substitute for the hard bargaining between the parties that actually holds.
Kenya's mediation role is worth sustaining — it brings genuine value to a region that desperately needs credible conveners. But it should be understood for what it is: a contribution to a process that requires many actors working in concert, not a solution Kenya can deliver on its own. The risk of over-relying on Kenya's goodwill is that it places an unsustainable burden on a country that has its own significant domestic challenges and whose political leadership changes with each election cycle. Regional peacemaking needs institutions, not just individuals willing to host dinners in Nairobi.
