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 says he’ll impose new economic penalties on Russia in 10 to 12 days if Putin can’t agree to a ceasefire. His “secondary sanctions” would target the oil trade.

President Trump said he had decided to shorten a 50-day deadline he had given Russia to end the conflict or face punishing new sanctions.
