Around 22,000 militants have been killed by the US-led coalition fighting the so-called Islamic State group since mid-2014, according to the French defence minister.
"The figure given by the coalition... is about 22,000 dead since the start of operations in Iraq and Syria," Jean-Yves Le Drian told the France24 news channel, adding that the figure was "approximate".
He also sounded upbeat about a series of military successes against IS in recent months.
"We haven't seen a large offensive by Daesh for some time," Mr Le Drian said, using an alternative name for the group.
"Daesh is in a very fragile position but we must remain very careful," he added.
The coalition air strikes against IS began in the summer of 2014 and intensified following last November's jihadist attacks in Paris, with strikes notably targeting IS oil production facilities, a key source of income for the group.
In a major setback for the group, IS lost the Iraqi city of Ramadi to US-backed local forces last month.
Peace talks to begin next week
Meanwhile, the US Secretary of State has said that peace talks will go ahead in Switzerland next week, despite rival camps bickering about who should be invited to take part.
John Kerry has conceded that the talks may not start as scheduled on Monday 25, but said there would be no fundamental delay.
Mr Kerry said the initial talks would be "proximity talks", rather than face-to-face meetings.
Countries backing the talks, including the United States, Russia, Saudi Arabia, Iran and Turkey, are still at odds over which fighting groups should be branded "terrorists", a discussion that is expected to continue until the talks begin.
