Mr Macron made the announcement on a visit to Ivory Coast, where he reiterated France’s commitment to fighting jihadists in the region.
It comes weeks after 13 French troops died in a helicopter collision in Mali in the biggest single-day loss of life for its military since the 1980s.
Thousands of French troops have been deployed in Mali since 2013.
Its involvement came after Islamist militants overran parts of the north. With the help of France, Mali’s army has recaptured the territory, but insecurity continues and violence has spread to neighbouring countries.
