Diplomatic thaw between Niger and Bénin after border standoff

After three years of strained relations, Niger and Bénin appear to be easing tensions along their shared frontier. The recent visit of Niger’s Prime Minister, Ali Lamine Zeine, to Cotonou for the inauguration of Bénin’s newly elected President, Romuald Wadagni, marked a rare moment of direct diplomatic engagement between Niamey and Cotonou. During the visit, Zeine emphasized the need to forge a “new path” between the two nations, signaling the potential thaw in relations following a prolonged dispute that intensified after the July 2023 coup in Niger.

The closure of the Malanville border crossing, a critical commercial artery connecting the two countries, stemmed from sanctions imposed by the Economic Community of West African States (ECOWAS) on Niger’s military leadership. Since then, trade flows—including hydrocarbons, foodstuffs, and other goods—have been rerouted through Burkina Faso and Togo, driving up operational costs for businesses on both sides of the border.

Economic fallout from a closed frontier

The port of Cotonou has historically served as Niger’s primary maritime gateway, given the landlocked nation’s structural isolation. Its exclusion from trade routes has strained Bénin’s customs revenues and disrupted supply chains in Niamey, particularly after the launch of the Agadem oil pipeline linking Niger’s fields to the Sèmè-Kpodji terminal in Bénin. Tensions over this infrastructure, operated in partnership with the China National Petroleum Corporation (CNPC), deepened the rift between the two capitals in 2024.

For border communities, the closure has choked off livelihoods in towns dependent on cross-border transit. Informal traders, transporters, and small-scale merchants have resorted to risky detours via secondary routes, fueling an unregulated parallel economy. Economist Olivier Vallée, a former technical advisor in Niger, notes that an official reopening would bring immediate relief to households on both sides of the divide.

Security concerns delay reconciliation

Yet, lingering security risks remain the biggest obstacle to normalization. Bénin grapples with rising violence linked to Islamic State-affiliated groups and the Support Group for Islam and Muslims (JNIM), particularly in the W and Pendjari national parks near the tri-border area with Niger and Burkina Faso. Cotonou fears that an unregulated reopening of Malanville could enable the movement of fighters and logistical support to armed cells operating in the region.

Niger’s transitional authorities share similar apprehensions. They accuse Bénin of harboring opponents of the military government after the 2023 coup, allegations that Cotonou has consistently denied. This climate of mutual distrust explains why, according to Vallée, both sides remain wary of potential infiltrations—whether jihadist or political.

Reconciliation hinges on safeguards

The ascent of Romuald Wadagni to the presidency in Bénin has introduced a new variable into the equation. A former Finance Minister with strong ties to international donors, Wadagni inherits a dossier where economic imperatives favor swift détente. The resumption of Niger’s crude oil exports via Bénin’s terminal represents a multi-billion-franc CFA annual revenue opportunity for both treasuries.

The timeline for reopening remains uncertain. Key steps include implementing stricter border control protocols at Malanville, reactivating a joint security commission, and resolving the status of nationals from both countries stranded since 2023. The geopolitical landscape adds another layer of complexity: Niger’s exit from ECOWAS—alongside Mali and Burkina Faso—to form the Sahel States Confederation introduces institutional hurdles to cooperation. Observers view the gesture in Cotonou as the most tangible political signal since the dispute began.
