Niger-Benin: a narrow window for diplomatic reset

This briefing by the Institute for Security Studies argues that the election of Romuald Wadagni as president of Benin on 12 April 2026 provides a strategic opportunity to reset diplomatic relations with Niger and reduce regional tensions. The authors suggest that the African Union (AU), specifically through the AU Mission for Mali and the Sahel, is best positioned to facilitate this dialogue to address security and economic liabilities resulting from the current impasse.

• The election of Romuald Wadagni as Benin's president on 12 April 2026 is viewed as a potential catalyst for reopening dialogue with Niger, as Wadagni is seen as a technocrat who can rebuild trust without the baggage of the post-coup period.
• Relations between Benin and Niger have been severely strained since Niger's 2023 coup, characterized by border closures, mutual accusations of supporting coups, and disputes over a French military presence in northern Benin.
• Economic and security interdependencies persist despite diplomatic collapse, notably the Niger-Benin oil pipeline and the reliance of Niger on Benin's maritime corridor. Benin's port of Cotonou saw a 24% drop in vessel calls and a 34% drop in imports between Q1 2023 and Q1 2024.
• Security instability has increased in the border region, with violence across the Benin-Niger-Nigeria area rising by 86% from 2024 to 2025. A Jama’at Nusrat al-Islam wal-Muslimin attack in April 2025 killed 54 Beninese soldiers.
• The African Union (AU), particularly the AU Mission for Mali and the Sahel, is identified as the most credible actor to facilitate a diplomatic reset between the Alliance of Sahel States (AES) and ECOWAS member states.
