Russian President Vladimir Putin and U.S. President Donald Trump will meet in the coming days, Kremlin aide Yuri Ushakov confirmed on Thursday.

'At the suggestion of the American side, an agreement was essentially reached to hold a bilateral meeting at the highest level in the coming days, that is, a meeting between President Vladimir Putin and Donald Trump,' Ushakov said.

'We are now beginning concrete preparations together with our American colleagues,' he added in televised comments.

He did not say where the summit would take place. However, the Kremlin said it did not respond to a meeting between presidents Putin, Donald Trump and Volodymyr Zelensky that Trump's special envoy had proposed during a visit to Moscow.

'This option was simply mentioned by the American representative (Steve Witkoff) during the meeting in the Kremlin,' Kremlin aide Yuri Ushakov was quoted as saying by the state TASS news agency.
