Trump, who had previously expressed frustration with Vladimir Putin for undermining Zelensky's credibility and legitimacy, admitted he was "p*ssed off" with his Russian counterpart. This came after Putin insisted that war-torn Ukraine needed new leadership.

In a post on X on Sunday night, the 47-year-old Ukrainian President stated: "Right now, Russia continues looking for excuses to drag this war out even further. Putin is playing the same game he has since 2014."

"This is dangerous for everyone - and there should be an appropriate response from the United States, Europe, and all our global partners who seek peace."

Zelensky's message on X followed Trump's warning that Russia could face a new round of severe economic sanctions due to the failure of peace negotiations. Speaking to NBC host Kristen Welker, Trump suggested these sanctions could include a tariff of between 25 and 50 percent on oil from Russia, reports the Mirror.

He also warned other countries that if they purchase oil from Putin's country: "you can't do business in the United States."
