President Donald Trump said Russia has yet to answer his ultimatum demanding progress toward a ceasefire in Ukraine, leaving Moscow with 10 days to comply before the United States considers punitive tariffs and other measures. Speaking to reporters aboard Air Force One after departing Scotland on 29 July, Trump called the lack of engagement from President Vladimir Putin "a shame" and confirmed that “no, I haven’t had any response.” The White House has not detailed the scale or scope of the tariffs being weighed. Trump first signaled a harder deadline a day earlier, saying he was "disappointed" in Putin and shortening what had been a 50-day window for action. The administration’s position raises the prospect of new economic pressure on Russia unless diplomatic progress is made quickly.
