What are the possible effects of meetings between U.S. officials and Putin on the Ukraine-Russia conflict?

White House envoy Steve Witkoff and Trump's adviser and son-in-law Jared Kushner are expected to meet Russian President Vladimir Putin in Moscow on Thursday and discuss the U.S. peace plan for Ukraine. Why it matters: The U.S. is close to agreement with Ukraine on the terms of a peace plan, but has so far had little clear success in getting Putin on board. The Russian president hasn't rejected the plan, but his public response to it has been less than enthusiastic. The fact that Russia has yet to accept the 20-point plan is one reason the White House didn't want to sign a "prosperity plan" for Ukraine during the World Economic Forum in Davos this week. Driving the news: Witkoff said in an interview with CNBC that he and Kushner would meet Putin on Thursday. The Kremlin later confirmed it. Witkoff and Kushner met on Tuesday in Davos with Putin's envoy Kirill Dmitriev and discussed the U.S. peace plan. Dmitriev called the meeting "constructive."The U.S. informed Ukrainian President Volodymyr Zelensky's team about the plan to travel to Moscow. Split screen: The crisis between the U.S. and its European allies over Greenland has pushed aside plans to hold talks on Ukraine in Davos. Ukrainian President Volodymyr Zelensky doesn't currently plan to travel to Switzerland after a massive Russian attack left parts of Ukraine facing water and electricity shortages amid a brutal winter.But Ukrainian officials said he could still travel to the Swiss Alps on Thursday if a bilateral meeting with Trump is scheduled
