U.S. officials will head to Moscow in person Thursday to ask Russian President Vladimir Putin to give his “blessing” to allow European representatives to join future peace talks for Ukraine.

Axar.az reports, citing Politico, that Jared Kushner, U.S. President Donald Trump’s son-in-law who has been mediating talks in Abu Dhabi, told reporters he and White House envoy Steve Witkoff will head to Moscow to meet the Russian leader.

They aim to secure Putin’s approval for Europe to get a seat at the table and to sign off on what would be the biggest prisoner exchange since the start of the war. Kushner said European participation is critical for discussions over revising the future security architecture of Europe — a longstanding Russian demand, and an initiative that has alarmed some European officials.

“We need to have the Europeans at the table,” Kushner told Politico. “We have relayed to President Putin directly several times and to his team that the only way to get this done is to have them by our side and I think they are receptive to it.

“I believe that hopefully tomorrow in Moscow, Steve and I will be successful and President Putin will give the blessing for that to occur. I think that if he agrees to that we will be able to make a lot more progress on the issues that matter.”
