"A few minutes ago, Ukrainian President Volodymyr Zelensky called me," Duda said on X.
"We had a candid conversation on the heels of the recent meetings with General Kellogg and other developments," he added.
"I conveyed to him that we consistently believe there is no other way to stop the bloodshed and achieve lasting peace in Ukraine except with the support of the United States," Duda revealed.
'Calm and constructive cooperation' with Trump
"For this reason, I suggested to President Zelensky to remain committed to the course of calm and constructive cooperation with US President Donald Trump," he wrote.
"I trust that good will and honesty form the foundation of the U.S. negotiation strategy," Duda further said.
Trump 'guided by deep sense of responsibility for global stability': Duda
The Polish president also shared that he was in "no doubt that President Trump is guided by a deep sense of responsibility for global stability and peace."
Trump on Wednesday denounced Zelensky as "a dictator without elections" and warned that he must "move fast" to secure peace with Russia or risk losing his country.
He also mocked Zelensky as "a modestly successful comedian" and accused him of talking the United States into spending USD 350 billion "to go into a war that couldn’t be won, that never had to start, but a war that he, without the U.S. and Trump, will never be able to settle."
Speaking to reporters in Florida on Tuesday, Trump blamed Ukraine's authorities for the war and suggested they "could have made a deal" with Russia earlier.
Russia invaded Ukraine by land, air and sea on February 24, 2022, starting the largest armed conflict in Europe since World War II.
Friday is day 1,093 of Russia's war on Ukraine.
