Zelensky and Trump will meet on Monday in Washington.

Ukrainian President Volodymyr Zelensky has announced that he has accepted an invitation from his US counterpart, Donald Trump, to discuss all the "details" of the conflict in Washington on Monday following the summit held this Friday in Alaska.

This will be the Ukrainian leader's first visit to the White House since the failed meeting in late February , when Trump and Zelensky had a tense discussion in the Oval Office, and this time it comes with the looming shadow of Putin's diplomatic isolation being broken.

Trump and Zelensky have already spoken by phone following the Alaska meeting—"a long and substantial conversation," in the Ukrainian president's words. Zelensky explained on social media that they first had a private, hour-long conversation, which was later joined by other European leaders.

"It's important that the United States' strength has an impact on the development of the situation," said Zelensky, who again advocated extending the negotiations to a three-way format, with Kiev also participating.

"Ukraine reaffirms its willingness to work with maximum effort to achieve peace," he added.

The Ukrainian president believes it is "important" for European countries to "be involved in all phases," with a view, for example, to adopting the security guarantees that Ukraine is demanding, in which Zelensky hopes the United States will also be involved.
