Earlier this month, Trump set a 50-day deadline for Russia to accept a ceasefire. Failure to do so, the president said, would prompt punishing new economic measures, among them secondary sanctions on nations doing business with Moscow.

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.”
