Ukrainian President Volodymyr Zelensky said on Wednesday that he would listen to former President Donald Trump’s ideas on how to end the war in Ukraine “with pleasure.”

The comments came at the annual Delphi Economic Forum in Athens, Greece, in which world leaders were invited to discuss “Politics, Business, Diplomacy, and Civil Society.” In a remote interview from Ukraine, Zelensky was asked about a purported “secret plan” by Trump to end the war, to which he responded that he would “with pleasure listen to [ideas] and then we can discuss the topic,” according to CNN.
