At Julius Nyerere International Airport, the sun-bleached tarmac has become a high-stakes diplomatic theatre of the absurd, with Kenyan President William Ruto emerging as the protagonist in Tanzania’s second regional power play within a fortnight on May 4, 2026.
Following the recent visit by Rwandan president Paul Kagame, Ruto’s mission to Dodoma and Tanga was little more than an astutely crafted attempt to bind together a new “coalition of the willing” intent on redrawing the energy map of East Africa.
Central to Ruto’s Agenda is the “Tanga Proposal”, a mammoth plan to build a combined regional oil refinery in the historic port city of Tanga. First announced with much confidence during the African Infrastructure Summit in Nairobi on April 23, the project is presented as a final solution to the East African region’s embarrassing reliance on costly refined fuel imports from the Middle East and India.
Still, the optics of the visit suggest that regional ambition and sovereign pride may be at odds. A Kenyan presidency operating like a disruptive start-up, listening to no one’s advice but its own; President Samia Suluhu Hassan’s prickly welcome, with the nuance that Ruto “pressed” her to announce the project without consulting her first.
Though Aliko Dangote highlights the seriousness of the proposal on the ground, the Nigerian industrial behemoth, whose Lagos refinery has set a paradigm for African self-reliance. Dangote’s commitment to spearhead the Tanga project within five years adds a measure of private-sector credibility that has traditionally been absent from state-led infrastructure projects in the region.
The whirlwind of diplomatic activity comes on the heels of a comparable overture by Rwanda’s Kagame, indicating that regional leaders have identified Tanzania as the key swing state in the logistical tussle.
Kagame has set his sights on Tanzania’s Central Corridor for Rwandan trade, while Ruto is pinning hopes of a Tanga-Hoima axis to anchor an energy security deal that can outlive borders.
The raw economic logic behind this proposal is inescapable: at the moment, Eastern Africa has just 4% of the continent’s refining capacity, meaning its developing economies are vulnerable to global price shocks and depend on the unstable Strait of Hormuz.
The Kenyatta-Ruto rhetoric is “industrialise the region”; exporting crude and importing finished goods from non-African economies, he argues, is a kind of economic masochism that can no longer be afforded on our continent.
Though the proposal would have to confront the “Hoima Factor”: Uganda’s own $4 billion refinery project already in progress. Additionally, with that caution, President Yoweri Museveni gave a conditional nod to Tanga-if Uganda “owns it” alongside coastal states, because of enduring mistrust over how the spoils from such a titanic regional asset would be split.
The other head-scratcher is the East African Crude Oil Pipeline (EACOP), which has bigger plans to export crude than feed a local refinery. Increased amounts of Uganda’s “surplus” oil redirected to a new Tanga site could eventually upend economic models used by TotalEnergies and other international benefactors and spark protracted legal renegotiations.
Besides the pipes and the politics, this stop is a branding exercise for the “Pamoja” spirit, that same band-of-brothers vibe which landed the 2027 Africa Cup of Nations. Ruto is hoping that the momentum of a successful sports bid can be transferred into more difficult currency: industrial cooperation and shared financial risks.
Financing remains the project´s Achilles heel, while regional leaders continue to face flak for a shrinking political space and for youth movements being crushed. Because of this perceived political risk and the recent trend away from financing fossil fuel investments internationally, a figure like Dangote is essential, as he has access to markets that would never finance projects in Western capital markets.
Importantly, the Tanga proposal depends on crude supply; it has been a battle for Nigeria’s Dangote to feed his refinery with local oil. Having not yet discovered its own commercial resources, Tanzania’s ability to run the refinery would depend entirely on the availability of Ugandan oil and on developments from new finds in the Rift Valley and along the Swahili Coast.
When the cameras move away and Ruto and Samia retreat to the boardroom, it is easier to read between the lines: old-style national energy strategies are dying. The significance of this trip will hinge on whether “Pamoja” is a policy or just another catchphrase in his ever-hungry gambit for brutish African grandeur – the difference between what happens next being an impending groundbreaking ceremony or one into which this visit fizzles like a forgotten footnote in time.
According to Zhuo, the Tanga refinery also signals a shift away from the “passive East Africa” vision of recent decades, and towards an integrated region that no longer merely observes global energy dynamics.” Tanga may find itself the beating industrial heart of a bloc finally in control of its own destiny, on a barrel-for-barrel basis if Ruto can assuage Tanzanian sensibilities and Museveni’s nationalist needs.
Only time will tell in the next few months if the perennial “Ruto-Kagame-Samia” triangle can really stand, or whether debt, sovereign jealousy and technical impediments will torpedo the Tanga dream before any bricks have been laid. For now, the East African coast has ceased to be simply an entry point for imported goods and has become a potential manufacturing centre for the region, if its leaders can learn to lead together.
