Ukraine's President Volodymyr Zelensky said Tuesday he expected to hold a summit soon with the leaders of Russia, France and Germany, after meeting French leader Emmanuel Macron in Kyiv.

"We expect that in the near future... we will be able to hold the next talks between the leaders of the Normandy quartet," Zelensky told a press conference, referring to negotiations aimed at ending the festering conflict in eastern Ukraine.

Ukraine's Foreign Minister Dmytro Kuleba on Monday warned Moscow against trying to split Kyiv from its Western allies, as European leaders push to defuse tensions over Russia's troop build-up on its neighbor's border.

"No one, no matter how hard anyone tries in Russia, will be able to drive a wedge between Ukraine and its partners," Kuleba said at a press conference with his German counterpart Annalena Baerbock in Kyiv.

French President Emmanuel Macron on Monday held talks at the Kremlin with Russian leader Vladimir Putin in a bid to try to de-escalate fears Moscow could be planning a full-scale invasion of Ukraine.

European leaders are scrambling to ease the crisis on the continent's eastern fringes, but have warned the Kremlin of "massive consequences" if it stages an incursion almost eight years after seizing Crimea from Kyiv.
