President Trump says secondary sanctions against Russian oil-purchasing nations will go into effect next week if Putin doesn't agree to Ukraine peace deal within 10 days.

U.S. President Donald Trump said on Tuesday that the United States would start imposing tariffs and other measures on Russia "10 days from today" if Moscow showed no progress toward ending its more than three-year-long war in Ukraine.

Ukrainian President Volodymyr Zelensky’s right-hand man lauded President Trump Tuesday for shortening the time frame for Russia to show willingness to make peace with Kyiv — saying it will let Vladimir Putin know that Washington is “serious” about ending the war in Ukraine.
