France will cut its troops in Mali to 1,600 by the middle of February from the current level of 2,500, President Francois Hollande has said.
Speaking at an airbase in Creil in northern France on Wednesday, Hollande said the "situation is well under control" in Mali, where the "key objectives of the mission have been accomplished".
"The troop size will be reduced from about 2,500 at present to 1,600 and then to 1,000, which is the number necessary to fight any threat that might resurface as these terrorist groups are still present in northern Mali," the president said.
He also announced that France plans to use two unarmed Reaper drones to survey the region.
France launched Operation Serval in its former colony in January 11 last year to repel the advance of al-Qaeda linked armed groups following a coup. At the height of the operation, 5,000 troops were deployed.
A UN mission also deployed more than 12,000 troops.
The French intervention sought to stop armed groups and Tuareg rebels from advancing on the capital, Bamako.
The armed groups that once controlled northern Mali are believe to have been killed, or dispersed elsewhere in the Sahel region, notably to southern Libya.
