Following the July 2023 coup in Niger and the subsequent imposition of stringent regional sanctions, the Cotonou-Niamey axis endured a profound period of strain. This crisis was starkly characterized by hermetically sealed borders and a barrage of accusations from Niger. However, a closer examination reveals a more nuanced reality: despite the firm stance of the Alliance of Sahel States (AES), Bénin consistently pursued avenues for conciliation. The recent official visit by Bénin’s new president, Romuald Wadagni, to Niamey stands as a definitive culmination of this outstretched diplomatic hand, an undeniable testament to Cotonou’s genuine intentions.
A steadfast commitment to de-escalation despite obstacles
While the crisis intensified over several months, Bénin initiated concrete steps early on to ease tensions:
- Prompt lifting of economic sanctions: By late 2023, Bénin rescinded suspensions on the transit of goods destined for Niger via the autonomous Port of Cotonou. Cotonou aimed to reopen Niger’s economic lifeline, but Niamey maintained its border closure, citing “security reasons.”
- Diplomacy through emissaries: As the stalemate persisted, Béninois authorities actively encouraged and facilitated high-level mediations. Efforts undertaken in Niamey by former Béninois presidents Nicéphore Soglo and Thomas Boni Yayi in summer 2024 underscored Cotonou’s unwavering commitment to re-establish dialogue, transcending political divides.
- Safeguarding shared interests: Despite intense friction surrounding the WAPCO Niger-Bénin crude oil export pipeline terminal, Bénin consistently prioritized the preservation of this vital infrastructure. This pragmatic management prevented an irreversible rupture and maintained the sole technical umbilical cord connecting the two nations.
The arrival of Romuald Wadagni: an opportunity for a fresh start
The election and inauguration of Romuald Wadagni as Bénin’s president in May 2026 presented a significant window of opportunity. A highly respected technocrat and former Finance Minister, the new head of state possesses invaluable political neutrality, as he is not associated with the more divisive decisions made in the post-2023 coup period.
The first strong signal emerged from Niamey, with Nigerien Prime Minister Ali Mahamane Lamine Zeine traveling to Cotonou to attend Wadagni’s inauguration, effectively breaking a prolonged diplomatic isolation.
The ultimate pledge of goodwill
By choosing Niamey as one of his very first official destinations, Romuald Wadagni delivered the “pledge of goodwill” that the AES regimes had long demanded. This presidential visit unequivocally demonstrates Bénin’s commitment to regional reconciliation as a top priority. By directly engaging with General Abdourahamane Tiani and Captain Ibrahim Traoré, Romuald Wadagni signals his government’s readiness for frank, pragmatic, and unconstrained dialogue.
Interdependencies necessitate pragmatism
This diplomatic thaw transcends mere symbolism; it addresses urgent and shared realities:
- The security imperative: Armed violence in the shared cross-border region (the W-Arly-Pendjari complex) surged by nearly 86% between 2024 and 2025. Neither nation can effectively combat the jihadist threat in isolation. The restoration of bilateral military cooperation is a matter of survival for border populations.
- Economic asphyxiation: Niger critically needs the Béninois corridor to reduce the cost of living and secure its supply chains. Bénin, in turn, seeks to boost revenues from the Autonomous Port of Cotonou.
By venturing into the heart of the AES, Romuald Wadagni definitively turns the page on past misunderstandings. Bénin demonstrates its respect for its neighbors’ sovereignty and its full commitment to shared stability and prosperity in the sub-region. The onus is now on Niamey to capitalize on this diplomatic success and facilitate a complete reopening of the borders.
