President Trump said Wednesday that Russian President Vladimir Putin must agree to a ceasefire at their summit on Friday or face "very severe consequences."

Axar.az, citing Axios, reports that the warning marks a shift from Trump’s earlier low expectations for the meeting in Alaska.

In a call with Ukrainian President Volodymyr Zelensky and European leaders, Trump stated his goal was to secure a ceasefire and gauge prospects for a full peace deal, hinting that land swaps could be part of the solution.

Zelensky cautioned that Putin “cannot be trusted,” while European leaders pressed Trump to maintain strong pressure on Moscow.

German Chancellor Friedrich Merz and other leaders emphasized that Russia should not gain legal recognition of the occupied territories.

Trump remains cautiously optimistic but acknowledged that success is uncertain. Zelensky urged a trilateral summit with himself, Trump, and Putin, which Trump supports but Putin has not agreed to.

Trump made clear in his remarks to the press later on Wednesday that he views success as far from guaranteed. Asked if he believed he could convince Putin to stop targeting civilians in Ukraine, Trump replied: "I guess the answer to that is no, because I've had this conversation [with Putin]."
