A diplomatic scramble unfolded Saturday after President Donald Trump announced he would meet his Russian counterpart, Vladimir Putin, next week in Alaska, as European leaders rushed to understand the terms of the meeting and ensure Ukraine was not being left out of discussions about its future.

President Donald Trump and Russian President Vladimir Putin agreed to meet Friday in Alaska and might invite Ukrainian President Volodymyr Zelensky, too.

Kyiv has repeatedly rejected any so-called "land swap" which would be against the Ukrainian Constitution. Zelensky's comments on Saturday acknowledge Trump's role in any peace deal with the summit but again reject the chances that Ukrainian land can be traded for peace.
