France wants international supervision to implement a ceasefire in the Nagorno-Karabakh conflict amid concerns in Paris that Russia and Turkey could strike a deal to cut out Western powers from future peace talks, the presidency said on Thursday, Reuters reports.

Moscow co-chairs the Minsk group overseeing the Nagorno-Karabakh dispute with Washington and Paris, but they were not involved in the deal signed by Russia, Armenia and Azerbaijan to end six weeks of fighting.

“The end of the fighting should now allow the resumption of good faith negotiations in order to protect the population of Nagorno-Karabakh and ensure the return of tens of thousands of people who have fled their homes in recent weeks in good security conditions,” President Emmanuel Macron’s office said after calls with the Azerbaijani president and Armenian prime minister.

“We want the Minsk Group to play its role in defining the surveillance (of the ceasefire),” a French presidential official told reporters.

The source said Paris was pushing for “international supervision” of the ceasefire to allow the return of refugees, organize the return of foreign fighters, especially from Syria, and to start talks on the status of Nagorno-Karabakh.
