A week after Donald Trump applauded Vladimir Putin down the red carpet in Alaska, and days after an unprecedented summit of European leaders at the White House, the American president came crashing down to earth on Friday.

U.S. President Donald Trump renewed a threat to impose sanctions on Russia on Friday if there is no progress toward a peaceful settlement in Ukraine in two weeks, showing frustration at Moscow a week after his meeting with Russian President Vladimir Putin in Alaska.

President Donald Trump again threatened Russia with “massive sanctions” over the war in Ukraine unless an agreement can be reached in about two weeks, swerving back to a tougher stance after an inconclusive meeting with President Vladimir Putin.

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.
