Russia’s top diplomat said in an interview released on Friday that “there is no meeting planned” between President Vladimir V. Putin of Russia and President Volodymyr Zelensky of Ukraine. It was the Kremlin’s most direct declaration yet that a summit the White House suggested was imminent was nowhere close to materializing.

The denial of a Putin-Zelenskyy meeting comes days after Donald Trump said he had begun arrangements for them to sit down together.

President Trump said in a social media post Monday that he had spoken to Russian President Vladimir Putin and set in motion arrangements for a summit at a location to be decided.
