Multiple sources have told AFP that Macron will announce that French forces will leave Mali and redeploy elsewhere in the Sahel region, following a breakdown in relations with the ruling junta.
Macron is to travel to Brussels Thursday for a two-day EU-Africa summit. But the French presidency announced he would hold an 0800 GMT press conference at the Elysee on the "engagement of France in the Sahel", where he is likely to make the formal announcement.
The Mali deployment has been fraught with problems for France. Of the 53 soldiers killed serving in its Barkhane mission in West Africa, 48 of them died in Mali.
France initially deployed troops against jihadists in Mali in 2013 but the insurgency was never fully quelled, and now new fears have emerged of a jihadist push to the Gulf of Guinea.
The deployment in Mali of a European force known as Takuba -- a project driven by Macron to spread the security burden in the troubled region -- will also end, the sources said.
The expected announcement of the withdrawal comes at a critical time for Macron, just days ahead of a long-awaited declaration from the president that he will stand for a new term in April elections.
It also coincides with Macron seeking to take a lead role in international diplomacy as he presses Russia to de-escalate in the standoff over Ukraine.
African Presidential Comment
Ivory Coast President Alassane Ouattara warned Wednesday that the expected withdrawal of French and other European forces from Mali would "create a vacuum", pushing West African armies into the front line in the fight against jihadism.
The expected departure of France's Barkhane Sahel mission and a French-led European force called Takuba "creates a vacuum. We will be obliged to buy weapons, to have a greater professionalization but it is our duty too," Ouattara said in an interview with French media RFI and France 24.
"The national armies must solve the problems on our national territories and that is our philosophy."
The working dinner hosted by Macron on Wednesday, starting at 1930 GMT, will bring together the leaders of France's key allies in the Sahel region -- Chad, Mauritania and Niger.
Officials from Mali and Burkina Faso, which also recently experienced a coup, have not been invited.
Other African leaders will also be present along with European Council President Charles Michel and European Commission chief Ursula von der Leyen, and Italian Prime Minister Mario Draghi.
There are a total of 25,000 foreign troops currently deployed in the Sahel region.
They include around 4,300 French soldiers, which under a reduction announced last year are due to fall to around 2,500 in 2023 from a peak of 5,400.
Other forces deployed in Mali are the UN peacekeeping mission MINUSMA established in 2013 and the EUTM Mali, an EU military training mission that aims to improve the Malian military's capacity in fighting terrorists.
Some 2,400 French soldiers are deployed in Mali as part of the Barkhane operation as well as the EU Takuba force set up in 2020, which was intended to increase in numbers as French deployment was scaled back.
According to a French source, who asked not to be identified by name, even after departure France will for a period provide MINUSMA and EUTM with air support and medical back-up.
But Paris' withdrawal could set the stage for other European powers like Britain or Germany to abandon their roles in the multinational missions.
"The departure of Barkhane and Takuba creates a void," Ivorian President Alassane Ouattara said Wednesday.
In the Sahel and Gulf of Guinea, "national armies will have to deal with problems on our national territories, and that's our philosophy", he told broadcasters RFI and France 24.
Relations between France and Mali have plunged to new lows after the junta led by strongman Assimi Goita refused to stick to a calendar to a return to civilian rule.
The West also accuses Mali of using the services of the hugely controversial Russian mercenary group Wagner to shore up its position, a move that gives Moscow a new foothold in the region.
Especially with the French elections looming, Macron's priority is to ensure that any withdrawal does not invite comparisons with the chaotic American departure from Afghanistan last year.
Paris, however, intends to continue the anti-jihadist fight in the wider region, where movements affiliated with Al-Qaeda or the Islamic State group have retained an ability to attack despite the elimination of key leaders.
"We need to reinvent our military partnership with these countries," said a French presidential source.
"It is not a question of moving what is being done in Mali elsewhere, but of reinforcing what is being done in Niger and of supporting the south more."
