Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.

Though endlessly critical of his predecessor, President Trump has adopted a Ukraine strategy similar to that of former President Joe Biden: Arm the Ukrainians to the teeth and threaten Russian President Vladimir Putin with even more sanctions if he does not agree to a peace deal.

Ukrainian President Volodymyr Zelenskiy also held talks with a U.S. envoy on Monday on increasing weapons production and arms purchases.
