"I think that, and then I am going to Moscow with Jared [Kushner]... And I will leave Thursday night and arrive in Moscow late at night," Witkoff told CNBC.
In a separate interview with Bloomberg, Witkoff said that significant progress has been made in recent weeks toward resolving the Ukrainian conflict.
"I know we have made more progress in the last six or seven weeks since Geneva than we have made ... in the last three or four years," he said.
Kremlin spokesman Dmitry Peskov confirmed that the meeting is scheduled for Thursday.
“Yes, indeed, such contacts are on the president’s schedule for tomorrow,” Presidential spokesman Dmitry Peskov told Russian media.
Witkoff also said that he plans to hold a meeting with Russian President Vladimir Putin on Thursday, Reuters reported, quoting Witkoff's interview with CNBC.
Witkoff and Putin last met on December 2. He visited Russia six times last year. The last time the US president’s son-in-law, Jared Kushner, traveled to Moscow with him.
