Zelensky Pushes Back Against U.S. Mineral Deal and Announces European Summit

President Volodymyr Zelensky pushed back on Sunday against demands from the Trump administration for billions in Ukrainian natural resources and for holding peace talks that exclude Ukraine, while announcing plans for a major summit of European leaders on Monday.

The Ukrainian leader’s efforts to shore up European support while pressing ahead on negotiations with the United States came despite ominous messages from President Trump in recent days belittling Mr. Zelensky and issuing threats if Ukraine does not soon agree to a minerals deal.

Mr. Zelensky suggested that in assailing Ukraine, Mr. Trump had chosen the wrong adversary.

“Peace through force, but toward Russia, not in the other direction,” Mr. Zelensky said of how he would like to see American efforts to end the war.

Mr. Zelensky, speaking at a news conference in Kyiv, said that he was willing to step down if it meant peace in Ukraine. His remark came days after Mr. Trump questioned his legitimacy and called him a “dictator without elections,” echoing a Kremlin talking point.

It was not immediately clear whether Mr. Zelensky is seriously considering the option of stepping down or was merely responding to the latest jabs from Washington and Moscow. He added that he would trade his departure for Ukraine’s entry into NATO — perhaps a tongue-in-cheek offer, since both Mr. Trump and President Vladimir V. Putin of Russia solidly oppose Ukraine’s joining the military alliance.

“If peace for Ukraine requires me to step down, I’m ready,” Mr. Zelensky said on the eve of the third anniversary of Russia’s full-scale invasion. “Another scenario: I could trade my position for NATO membership, if that’s what it takes,” he added.
