Niger-Benin: a narrow window for diplomatic reset

The briefing examines the strained bilateral relationship between Benin and Niger following Niger's 2023 coup and the subsequent withdrawal of the Alliance of Sahel States (AES) from ECOWAS. It highlights how the election of Romuald Wadagni in Benin on 12 April 2026 offers a window for de-escalation, as both nations face economic losses and rising insecurity. The author suggests that the African Union, specifically through the AU Mission for Mali and the Sahel, is best positioned to facilitate a formal reset based on mutual territorial assurances to overcome mistrust and security gaps in the W-Arly-Pendjari Complex.

• The relationship between Benin and Niger has 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 interdependencies persist despite diplomatic collapse, most notably the Niger-Benin oil pipeline, which has continued to operate intermittently despite both nations attempting to weaponize it in 2024.
• The diplomatic crisis has caused significant economic damage to Benin's port of Cotonou, where imports dropped by 34% and the number of vessels decreased by approximately 24% between Q1 2023 and Q1 2024.
• Security in the Benin-Niger-Nigeria border region has deteriorated, with violence increasing by 86% from 2024 to 2025, including a deadly attack in April 2025 that killed 54 Beninese soldiers.
• The African Union (AU) is identified as the most credible facilitator for a reset, specifically through the AU Mission for Mali and the Sahel, which can leverage its Bamako base and engagement with both AES and ECOWAS.
