Niger-Bénin border remains closed as Chad’s French military ties challenge Niamey’s stance

The Niger-Bénin border: a lingering impasse

While Niamey maintains the closure of its border with Bénin, citing demands for robust security guarantees, a sensitive question now confronts Niger: if a French military presence in a neighboring state justifies border closure, should this logic not also extend to Chad, where French forces are making a return?

The shared border between Niger and Bénin continues to be shut. Nearly three years after the July 2023 coup d’état, the anticipated normalization between Niamey and Cotonou has yet to culminate in the effective reopening of this vital artery for regional trade and movement.

Despite this, recent months have seen multiple signs of a thaw in relations. Both nations have re-engaged in dialogue, establishing a technical framework tasked with assessing the prerequisites for reopening. These discussions have also facilitated progress on critical security, economic, and legal fronts.

Yet, Niamey stands firm on its demands.

In a recent public address, General Abdourahamane Tiani articulated that the border’s reopening must be contingent upon guarantees, specifically concerning security and the assurance that no forces deemed hostile would be positioned near the frontier. This stance aligns with the long-held position of Nigerien authorities: Niamey insists that Béninese territory must not serve as a staging ground for operations that could threaten Niger.

The core issue is that Cotonou vehemently disputes this accusation.

Cotonou and Paris refute allegations

Since the onset of the crisis, Béninese authorities have consistently rejected claims suggesting France operates military bases within Bénin, particularly in its northern regions.

The Béninese government firmly asserts it has never hosted a foreign military base on its soil. This point was reiterated by Bénin’s Minister of Foreign Affairs, Olushegun Adjadi Bakari, in January 2025.

Paris has also denied the existence of any French military base in northern Bénin. In March 2026, the Chief of Staff of the French Armed Forces, General Fabien Mandon, dismissed these accusations, affirming that no French base exists in that part of the country.

However, a crucial nuance must be acknowledged.

France does indeed provide security support to Bénin. French military personnel have been involved in training and assisting Béninese forces confronting armed groups in the country’s north. Reports in April 2026, for instance, detailed the discreet presence of French special forces operating alongside Béninese troops. French authorities officially describe these personnel as trainers.

Therefore, a distinction must be drawn between two separate matters: the existence of Franco-Béninese military cooperation, which is not denied, and the presence of a French military base or a permanent French deployment near the Nigerien border, which both Cotonou and Paris deny.

It is precisely this distinction that forms a central part of the ongoing debate.

Niamey’s new foreign policy equation

As Niger demands guarantees from Bénin, another of Niger’s neighbors is rekindling its relationship with Paris.

In November 2024, Chad had initially terminated its military cooperation with France, asserting its desire to fully exercise its sovereignty and diversify its security partnerships.

This French withdrawal was presented as a significant turning point in the relationship between N’Djamena and Paris.

Nevertheless, over recent months, the two capitals have been drawing closer once more. French military personnel are gradually returning to Chad, albeit within a much more discreet and scaled-down framework than previously existed.

This evolution is a response to pressing security realities: Chad faces the repercussions of the war in Sudan, the threat posed by Boko Haram in the Lake Chad basin, and substantial needs in intelligence, surveillance, and logistical capabilities.

N’Djamena may interpret France’s return as a sovereign and pragmatic choice.

Yet, for Niamey, this choice raises a fundamental question.

Chad, too, is a direct neighbor of Niger.

Consequently, if Niamey deems a French military presence near its territory a sufficiently grave threat to prevent the reopening of its border with Bénin, how does Niger intend to react to the Franco-Chadian rapprochement?

Why should Chad be different from Bénin?

This is where the true paradox lies.

Niamey could logically assert that every state is free to choose its military partners. Under this reasoning, Bénin would have the right to cooperate with France, and Chad would similarly have the right to renew ties with Paris.

However, if this logic is applied, it should then lead Niger to avoid making Franco-Béninese cooperation a decisive condition for reopening its border.

Conversely, if Niamey believes that French military cooperation in a neighboring country genuinely poses a threat to its national security, then the same reasoning should, logically, be applicable to Chad.

The question is not whether Niger should close its border with Chad.

Rather, it serves as a test of the consistency of Niamey’s argument.

Why would military cooperation with France be unacceptable for Niger’s western neighbor but acceptable for its eastern neighbor?

The geography makes this issue particularly sensitive. Niger shares an extensive border with Bénin, but also with Chad. Therefore, a foreign military presence in Chad can, theoretically, be considered part of Niamey’s immediate strategic environment.

France’s return to Chad: a test for sovereign doctrine

The Chadian situation unfolds within a dramatically transformed regional context. Mali, Burkina Faso, and Niger have elevated sovereignty and a rupture with former partner powers to a cornerstone of their new foreign policy. These three nations have exited ECOWAS and strengthened their cooperation within the Alliance of Sahel States.

Chad, however, has chosen a distinct path.

After severing ties with Paris in 2024, N’Djamena now appears to be resuming military cooperation with France, while simultaneously maintaining its other partnerships.

This decision is sovereign.

However, it might be difficult to reconcile with a conception of sovereignty that would deny neighbors the right to choose their own partners.

Thus, it is less the French presence in Chad and more the principle of consistency that now lies at the heart of the debate concerning African current affairs and regional governance.

Towards a resolution between Niamey and Cotonou?

The situation could still evolve. The ongoing discussions between Niger and Bénin indicate that both nations recognize the economic and security costs of their border closure. In the border region, local populations, traders, and transporters have endured the consequences of a political crisis, far exceeding their immediate interests, for nearly three years.

Furthermore, violence has significantly escalated in the border zone shared by Bénin, Niger, and Nigeria, underscoring the mutual benefit of enhanced security cooperation between the two countries.

A reopening of the border could, therefore, become a shared imperative.

To achieve this, however, Niamey and Cotonou will likely need to move beyond the issue of France.

The debate cannot sustainably remain confined to an opposition between “French presence” and “African sovereignty.”

If Niger seeks security guarantees from Bénin, it can legitimately request them. But these guarantees must be founded on verifiable facts, transparent mechanisms, and reciprocal commitments.

Crucially, they must be applied according to the same principles to all neighbors.

The gradual return of French military cooperation to Chad thus introduces a new dimension to this crisis.

Niamey is now faced with a choice: either acknowledge that every sovereign state is free to choose its partners, or uphold a doctrine where French military cooperation with a neighbor constitutes a threat justifying retaliatory measures.

In the first scenario, the reopening of the Niger-Bénin border could be facilitated.

In the second, the rapprochement between N’Djamena and Paris risks posing a question to Niger that will be difficult to avoid: if France is a threat in Bénin, why would it not be in Chad?

It is perhaps within this apparent contradiction that one of the primary challenges for Sahelian diplomacy currently resides: making sovereignty a principle universally applicable, rather than an instrument used selectively based on power dynamics between neighboring states.
