President Donald Trump said Friday he will give Russian President Vladimir Putin “a couple of weeks,” further extending a deadline for potential consequences against Moscow after urging the Russian leader and Ukrainian President Volodymyr Zelensky to meet.

The president, who had said a deal to end the war could be reached soon, expressed frustration over lack of progress and signaled he would pause his efforts.

Trump said Friday he expected to make a decision on his next actions in two weeks if direct talks aren’t scheduled.

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.

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

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.
