But despite the creation and the presence of 4,500 French soldiers and more than 14,000 United Nations peacekeepers, the jihadist groups have stepped up their attacks.
The French summit is expected to call for broader worldwide support for counterterror efforts in the region where the United Nations envoy for West Africa and the Sahel, Mohamed Ibn Chambas, last week said public confidence has been shaken by the "unprecedented terrorist violence".
Criticised in France for allowing French troops to get bogged down and facing growing hostility in West Africa for failing to restore stability, Macron has become increasingly frustrated, but the French leader appeared satisfied with Monday's results.

"The Pau summit is a turning point in our military strategy", declared the French leader during a press conference at Pau castle, hours after presiding over a wreath-laying ceremony at a memorial for several French soldiers who died in Mali last November.

The incident comes amid ongoing clashes between ISIS affiliate Boko Haram and government forces across West Africa. Beginning this year, "Task Force Takuba" is added to the response, bringing together special forces from European nations including Estonia.
The French military operation, France's largest overseas mission, enjoys broad support at home.
