Ukrainian President Volodymyr Zelensky said that he had a“productive“ conversation with US President-elect Donald Trump, CNN reports.

“We cannot yet know what his specific actions will be. But we hope that America will become stronger,” Zelensky said on Thursday. “This is the kind of America that Europe needs. And a strong Europe is what America needs.”

The Ukrainian president reiterated his message that Kyiv will pursue “peace through strength” rather than concessions of territory or neutrality.

“It is up to Ukraine to decide what should and should not be on the agenda for ending this war,” he added. “Any country, any leader who respects international law and sits at this table should understand that predators always demand more and more.”
