For nearly three years, a single closed border has quietly reshaped the fortunes of two West African nations. Benin has lost an estimated 30 million Dollars a year in export transit fees from Niger, its landlocked northern neighbour, because Niamey has refused to reopen its side of their shared frontier even after regional sanctions imposed over Niger’s 2023 coup were formally lifted. The standoff has drained trade, hardened political rhetoric, and left both governments navigating an insurgency that does not respect the line either side has drawn in the sand. Now, a new president in Porto-Novo is betting that pragmatism, not principle, offers the fastest way out.
Since his inauguration on 24 May 2026, President Romuald Wadagni has carried out a regional tour that included Burkina Faso and Mali as well as Nigeria, Togo, Guinea-Bissau, Senegal and Côte d’Ivoire. Niger was his second stop. Wadagni’s predecessor, Patrice Talon, had backed the Economic Community of West African States’ (ECOWAS) plans for military intervention after Niger’s July 2023 coup, setting off tit-for-tat economic policies between the two countries. Like other ECOWAS members, Benin initially imposed sanctions, including closing its border with Niger. At the time, 80% of Niger’s exports went through Benin. Porto-Novo reopened its side in February 2024, but Niamey continued the closure, saying Benin was harbouring French bases that would destabilise Niger. The standoff has cost Benin millions in transit fees, including from crude oil exports. China, which built a 4 billion Dollar crude oil pipeline between Niger and Benin, has unsuccessfully tried to mediate the impasse. Wadagni hopes for better luck.
Few diplomatic ruptures in the region have proven as costly as this one. Once Bazoum was toppled, ECOWAS responded with a broad sanctions package on Niger that included shutting borders, freezing Nigerien assets abroad, and halting financial transfers, a measure that touched every member state except the ones already suspended for coups of their own. Talon’s government fell in line with the bloc and, for a time, backed the prospect of armed intervention. Yet even once ECOWAS rolled back the bulk of its sanctions by early 2024, Niger’s military rulers refused to budge on the border, leaving Benin to absorb losses from a fight it hadn’t started alone.
The IMF cited the closure as a key reason it trimmed Benin’s 2023 growth outlook from 6% down to 5.4%, and the port of Cotonou, which once handled the vast majority of Niger’s transit trade, is still operating well below its pre-crisis capacity. Niger absorbed its own damage, rerouting shipments through pricier corridors via Togo and Burkina Faso and watching commercial hubs such as Gaya wither.
This is the closest the two sides have come toward a resolution in nearly three years. Delegations from Cotonou and Niamey closed out an initial round of technical talks on 21 June 2026, building on the nine-point roadmap struck when Wadagni became the first Beninese leader to visit Niger since the takeover.
Niamey, though, has signalled it won’t reopen the frontier on trust alone. Its negotiators have tabled two conditions they describe as non-negotiable: a bilateral non-aggression pact ruling out either country’s territory being used to destabilise the other, and full disclosure of any foreign military presence near Niger’s borders, backed by a shared intelligence cell. Both demands circle back to the accusation that has anchored the dispute from the start, that French troops based in Benin threaten Nigerien sovereignty, something Cotonou has repeatedly rejected. The path forward is further complicated by Benin’s own failed coup in December 2025, which stiffened attitudes on both sides and triggered tit-for-tat diplomatic expulsions in early 2026, a reminder of just how much domestic political exposure Wadagni is taking on with this outreach.
An economic co-operation reset is only the first goal. Benin also needs to secure a cohesive security collaboration with the Alliance of Sahel States (AES) as Sahel-based militants expand into coastal West Africa. Over the past year, Benin has suffered some of the deadliest attacks on security forces by al-Qaeda’s Sahel branch, Jama’at Nusrat al-Islam wal-Muslimin (JNIM). In the latest incident on 26 May, JNIM said it killed 12 Beninese soldiers in Koalou, near the Burkina Faso border. JNIM capitalised on a breakdown in defence co-operation after 2023, when Niger withdrew from the Multinational Joint Task Force, which includes Nigeria, Cameroon, Chad and Benin, to push southwards into northern Benin, where it has attempted to recruit from the country’s marginalised communities. That has had profound implications for Benin’s political stability. The purported leader of the December 2025 coup attempt, Lieutenant-Colonel Pascal Tigri, claimed the spreading insurgency as one of the reasons his group moved to depose the government in Porto-Novo. Tigri reportedly fled to Niger. Another figure linked to the coup attempt, Kémi Séba, who is facing extradition from South Africa to Benin, serves as an adviser to the Nigerien junta.
To grasp why Niger has held its ground for so long, it helps to look at its allies. Mali, Burkina Faso and Niger have moved well past loose junta-to-junta coordination and into something more permanent. What started in September 2023 as a mutual-defence pact was upgraded to a full confederation in July 2024, and by 29 January 2025 all three had formally quit ECOWAS, the very organisation they had helped establish back in 1975. Spanning roughly 2.78 million square kilometres and home to around 75 million people, the AES has since built out the trappings of statehood: a rotating annual presidency, a shared biometric passport, an investment bank, a common external tariff, its own flag and anthem, and a unified military force some 5,000 strong. Only one other country, Mauritania in 2000, has ever left ECOWAS, which makes this the bloc’s deepest crisis in fifty years of existence. The AES charter itself goes further than a typical security arrangement, declaring that an attack on the sovereignty of any one member counts as an attack on all three, with a standing commitment to respond collectively, militarily if needed.
That institutional split has come bundled with a wider pivot away from both Paris and Washington. Mali pulled out of the Organisation internationale de la Francophonie in March 2025 over what it called selective sanctions and disregard for sovereignty, and Burkina Faso and Niger have since taken comparable steps. When an expanded US travel ban targeting AES citizens took effect in December 2025, all three governments responded in kind with their own restrictions on American travellers. Russia has been the main beneficiary of the resulting vacuum, supplying military trainers and modest hardware, though none of the three juntas has yet proven able to turn back the jihadist tide, a gap some analysts believe could eventually strain the confederation from within. The pull of the bloc extends beyond its founding members too: Chad has cut its own defence ties with France, and Guinea’s military government has given the AES states quiet access to its ports, helping them sidestep the trade restrictions Ecowas still maintains.
JNIM’s push toward West Africa’s coast predates Niger’s 2023 coup but has accelerated since. Fighters crossed from Burkina Faso into Benin in 2021 and Togo in 2022, then entrenched across northern Benin and Niger’s Dosso region by 2024, using the shared W-Arly-Pendjari reserve as cover.
By April 2025, JNIM had killed more people in Benin than in all of 2024, prompting it to name a local Emir there, and in October 2025, it claimed its first attack in Nigeria, near the Benin border, reportedly with help from allied network Ansaru.
For the wider region, the stakes of this single border reach well beyond Benin and Niger’s finances. A durable reopening would offer the clearest sign yet that ECOWAS and the breakaway AES bloc can still find practical accommodation even without formal reconciliation, a template other strained relationships in the region might eventually borrow from. It would also restore a functioning trade network for a landlocked Sahelian state at a moment when coastal West Africa is trying to keep the jihadist insurgencies of the Sahel from taking permanent root along the Gulf of Guinea. A failure would solidify the sense that the region is settling into two rival camps, one anchored in ECOWAS and Western partnerships, the other in AES and Russian security ties, with knock-on effects for how neighbouring states like Togo, Nigeria and Côte d’Ivoire hedge their own economic and security relationships.
Whether that border reopens on schedule now depends on whether Cotonou and Niamey can turn their agreement into an enforceable defence and intelligence-sharing arrangement, something neither government has fully delivered on before. The deeper outcomes of these visits may take years to emerge, but for now Wadagni is giving intra-African co-operation a shot, at a time of growing geopolitical fragmentation.
