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.

Trump in July set a 50-day deadline for the agreement with Ukraine, threatening tariffs if a deal was not made. On Monday, during his meeting with U.K. Prime Minister Keir Starmer, he said he was shortening this deadline to “10 or 12 days.”
