US special envoy Steve Witkoff made upbeat remarks on ongoing Ukraine peace efforts at the World Economic Forum (WEF) in Davos on January 22, telling a breakfast meeting that we are at the end now. Im actually optimistic.

His comments came as diplomacy looked to once again speed up.

US President Donald Trump and Ukrainian President Volodymyr Zelenskyy are due to meet in Davos shortly, and Witkoff said he would depart for Moscow later in the day.

"I think we've got it down to one issue, and we have discussed iterations of that issue, and that means it's solvable. So, if both sides want to solve this, we're going to get it solved," Witkoff said.

He did not elaborate on what the sticking point was, but his comments contrasted withremarks by Trumpthe previous day, who ruminated on the difficulties of the peace talks.

What happens is, oftentimes well have a deal with Russia, Russias set, and President Zelenskyy will not do it. You saw that when he was in the Oval Office. I was not happy. And then, well have President Zelenskyy wants to make a deal and [Russian President Vladimir] Putin doesnt want to make a deal, Trump said.
