Yuri Ushakov, Russian President Vladimir Putin’s top foreign policy adviser, told reporters in Moscow that the changes introduced by European and Ukrainian negotiators would not increase the chances of reaching an agreement, according to the Reuters news agency.
Draft US proposals leaked to the media last month sought to outline a framework for ending the nearly four-year-old war but raised concerns in Kyiv and across Europe that the terms favoured Russia.
Ukrainian and European officials have expressed fears that the administration of US President Donald Trump could pressure Ukraine into making excessive concessions.
Since then, Ukrainian and European negotiators have held talks with US envoys in an effort to incorporate their own proposals into the draft plan, though the contents of the revised version have not been made public.
Ushakov's remarks came after Putin's envoy Kirill Dmitriev met on Saturday in Florida with US special envoy Steve Witkoff and Trump's son-in-law Jared Kushner.
Dmitriev was quoted as saying that discussions were expected to continue on Sunday.
The Florida meeting followed US talks on Friday with Ukrainian and European officials.
Ukrainian President Volodymyr Zelensky said on Saturday that Kyiv would support a US proposal for three-way talks involving the United States, Ukraine and Russia if they helped facilitate further prisoner exchanges and paved the way for meetings between national leaders, Reuters reported.
Ushakov dismissed the idea, according to Reuters, saying a proposal for such talks had not been seriously discussed and was not under active consideration.
