European leaders will join Trump-Zelenskyy meeting, signaling solidarity with Ukraine

"We will continue to support you for as long as it takes," she said, adding that the EU backs a trilateral meeting between Ukraine, Russia and the United States.

Zelenskyy said he hopes the upcoming meeting with Trump "will be productive" and not a repeat of the shouting match that took place in the Oval Office during his February visit.

After meeting with Putin, Trump said the Russian leader was willing to end the war in exchange for key Ukrainian territory concessions. Trump said Kyiv should take the deal with Moscow because "Russia is a very big power, and they're not."

"Since the territorial issue is so important, it should be discussed only by the leaders of Ukraine and Russia at the trilateral Ukraine, United States, Russia," Zelenskyy told reporters at the European Commission on Sunday. "So far, Russia has given no sign that the trilateral will happen," he added.
