Trump said the two leaders will meet next Friday. It remains unclear whether Ukrainian President Volodymyr Zelenskyy will be involved with the high-stakes summit.

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.

Donald Trump announced he would meet Vladimir Putin in Alaska next week, just hours after he said a peace deal in Ukraine might involve “some swapping of territories”. The US president wrote on his Truth Social platform on Friday that his “highly anticipated meeting” with the Russian leader would take place in Alaska on August 15.
