Chad and Niger share a 1,200 km border, a legacy of colonial rule that divided communities such as the Kanouri and Kanembou around Lake Chad and the Toubou in the desert north. Despite this artificial divide, the two nations have historically enjoyed close ties, with frequent exchanges of people, goods, and services. This proximity has fostered a sense of fraternity, with both countries using this term in their official communications. The relationship has been particularly strong in the realm of security cooperation.
In 2015, Chad deployed 2,500 soldiers to Niger's southeastern town of Bosso to combat Boko Haram, a militant group threatening the region. The Chadian military's successes, including the liberation of Malam Fatori, were praised by Nigerien President Mahamadou Issoufou. This cooperation was repeated in 2016, when 2,000 Chadian soldiers were deployed to Niger following a deadly attack on Bosso. This collaboration was part of a broader regional effort, involving the Multinational Joint Force, the Lake Chad Basin Commission, and the G5 Sahel, established in 2014.
The security cooperation between Chad and Niger was further formalized in 2018 with the signing of the Niamey Security Agreement, which also included Sudan and Libya. The agreement aimed to secure common borders and combat terrorism. In 2021, following the death of Chadian President Idriss Déby, his son Mahamat Idriss Déby chose Niamey for his first official visit, where he met with Nigerien President Mohamed Bazoum, who was designated as a facilitator in Chad's internal crisis.
Despite the coup d'état in Niger in July 2023, the two nations maintained their diplomatic channels. Mahamat Déby visited Niamey on July 30, 2023, where he met with Bazoum, General Tiani, and former President Issoufou. The Nigerien Prime Minister, appointed by the military, was received in N'Djamena on August 15, 2023, and made a third visit in February 2024. Chad, not being a member of the Economic Community of West African States (ECOWAS), has refused to take a hardline stance against Niger.
A significant moment in Chad-Niger relations was the visit of August 6, 2025, when the two presidents adopted a joint communiqué on security, energy, infrastructure, and free movement of persons. As part of this agreement, Niger committed to supplying diesel fuel to Chad, while Chad announced the opening of a consulate in Diffa, Niger. However, this cooperation has since deteriorated.
Tensions escalated in August 2023, when the Nigerien public television broadcast a testimony from a captain implicating several foreign actors, including Chad, Benin, Côte d'Ivoire, and France, in the country's internal affairs. General Tiani accused France and the presidents of Benin and Côte d'Ivoire of involvement. The situation worsened with a drone strike on October 24, 2023, in the Agadez region, which Niamey attributed to Chad.
The current state of Chad-Niger relations remains strained, with both countries navigating a complex web of alliances and rivalries. The historical ties of cooperation and fraternity between the two nations are being tested by recent developments. The international community is watching closely, as the stability of the Sahel region is at stake.
