French President Emmanuel Macron said Thursday that 26 of Ukraine’s allies have pledged to deploy troops as a “reassurance force” for the war-torn country once fighting ends in the conflict with Russia.

Macron spoke after a meeting in Paris of the so-called “coalition of the willing," a group of 35 countries who support Ukraine.

He said that 26 of the countries had committed to deploying troops in Ukraine — or to maintaining a presence on land, at sea, or in the air — to help guarantee the country’s security the day after a ceasefire or peace is achieved.

Earlier Thursday, Macron and other European leaders met with Ukrainian President Volodymyr Zelenskyy and the U.S. envoy for peace talks, Steve Witkoff, to discuss ways of ensuring long-term military support and continued American backing for Ukraine once the conflict ends. Zelenskyy also held a closed-door meeting with Witkoff.

Macron said at a news conference alongside Zelenskyy that the reassurance force “does not have the will or the objective of waging war against Russia," but will aim "to prevent any new major aggression and to involve the 26 states very clearly in the lasting security of Ukraine.”

Though details of any U.S. participation in the security guarantees remain unclear, both Macron and Zelenskyy said Washington had expressed willingness to be part of the plan, and the Ukrainian president said he was grateful about that.
