"The government of the Republic of Chad informs national and international opinion of its decision to end the accord in the field of defence signed with the French republic," foreign minister Abderaman Koulamallah said in a statement on Facebook.

Chad is a key link in France's military presence in Africa, constituting Paris's last foothold in the Sahel after the forced withdrawal of its troops from Mali, Burkina Faso and Niger.

"This is not a break with France like Niger or elsewhere," Koulamallah, whose country still hosts around a thousand French troops, told AFP.

At a press briefing after a meeting between President Mahamat Idriss Deby and Barrot, Koulamallah called France "an essential partner" but added it "must now also consider that Chad has grown up, matured and is a sovereign state that is very jealous of its sovereignty".

Barrot, who arrived in Ethiopia on Thursday evening, could not immediately be reached for comment.

- 'Historic turning point'-

Chad is the last Sahel country to host French troops.

It has been led by Deby since 2021, when his father Idriss Deby Itno was killed by rebels after 30 years in power.

The elder Deby frequently relied on French military support to fend off rebel offensives, including in 2008 and 2019.

The landlocked nation faces a potent threat from Boko Haram and other militant groups.

It borders the Central African Republic, Sudan, Libya and Niger, all of which host Russian paramilitary forces from the Wagner group.

Deby has sought closer ties with Moscow in recent months, but talks to strengthen economic cooperation with Russia have yet to bear concrete results.

Koulamallah called the decision to end military cooperation a "historic turning point", adding it was made after "in-depth analysis".

"Chad, in accordance with the provisions of the agreement, undertakes to respect the terms laid down for its termination, including the notice period", he said in the statement, which did not give a date for the withdrawal of French troops.

The announcement comes just days after Senegal's President Bassirou Diomaye Faye indicated in an interview with AFP that France should close its military bases in that country.

"Senegal is an independent country, it is a sovereign country and sovereignty does not accept the presence of military bases in a sovereign country," Faye told AFP on Thursday.
