Trump said on Tuesday he would probably meet Putin this month and dismissed Ukraine's concern about being left out of US-Russian talks in Saudi Arabia, while suggesting Kyiv could have reached a deal with Russia earlier.

Kremlin spokesman Dmitry Peskov said that the meeting in Riyadh was focused mostly on Russian-US bilateral ties but that it was a "very, very important step" towards reaching a settlement on the Ukraine conflict, nearing the end of its third year.

Putin and Trump's predecessor Joe Biden held a summit in Geneva in June 2021. That was the most recent time a US and Russian leader met face to face, though Biden and Putin had a call in February 2022 and messages were passed via intermediaries.
