The next round of U.S.-brokered peace negotiations between Ukraine and Russia is set to take place in Geneva next week as Russian President Vladimir Putin’s full-scale invasion of Ukraine is about to enter its fifth year.

According to Russian state news agency Interfax and Ukrainian officials, both sides scheduled talks for Tuesday and Wednesday, Feb. 17-18, in Switzerland. Ukrainian President Volodymyr Zelenskyy’s press office confirmed the time and venue to POLITICO on Friday and said the delegation had begun preparations.

Moscow will be represented by Vladimir Medinsky, a Putin aide who led the Russian delegation in talks in Istanbul last year. Ukrainian media have portrayed his inclusion as a negative signal for the negotiations.

After previous talks with Medinsky’s involvement, the Ukrainian delegation slammed the Russian official for delivering lengthy historical arguments. The Kyiv Independent recently described him as a “pseudo-historian.” Zelenskyy last week called Medinsky’s remarks “a historical briefing from a playbook that everyone has heard many times before.”

Two European officials and a senior U.S. official told POLITICO earlier this week that Washington had made clear to Kyiv it would not finalize security guarantees to protect Ukraine from future Russian aggression until an overall agreement to end the war is reached.

The previous round of negotiations took place in Abu Dhabi in early February. Russia and Ukraine recently carried out the first swap of prisoners since October last year.
