Russia “categorically” opposes any deal that allows European troops to act as peacekeepers in Ukraine, Foreign Minister Sergei Lavrov said.

“We see no room for compromise,” Lavrov told reporters Thursday at a news conference in Moscow. The presence of European forces in Ukraine would mean the “undisguised involvement of NATO countries in a war against the Russian Federation. It’s impossible to allow this,” he said.

French President Emmanuel Macron and UK Prime Minister Keir Starmer are working on proposals for a one-month truce in Ukraine covering air and maritime operations as well as energy infrastructure. That could be followed by a second phase involving deployment of troops, according to Macron. Meanwhile, Starmer spoke at a summit on Sunday of assembling a “coalition of the willing” to take part in peacekeeping operations in Ukraine.

European leaders are meeting in Brussels on Thursday for emergency talks on Ukraine and on defense spending. While U.S. President Donald Trump has said he wants to see a ceasefire in Ukraine, Russia has given no indication it’s willing to stop fighting as its troops gradually advance along the eastern Ukrainian front line.

Lavrov accused Macron of seeking to “fight Russia” and compared him to Napoleon and Hitler, after the French leader said in a televised address on Wednesday that he’ll enter into talks to extend his country’s nuclear shield to defend European allies.

“They said directly ‘We need to conquer Russia, we need to defeat Russia’,” Lavrov said. “He, apparently, wants the same thing, but for some reason he says that we need to fight Russia so that it does not defeat France.”
