The Kremlin on Monday dismissed a report from U.S. media claiming that Russian President Vladimir Putin and U.S. president-elect Donald Trump spoke by phone last week about the ongoing conflict in Ukraine.

The Washington Post reported on Sunday that Trump had called Putin on Thursday, urging him not to escalate the war in Ukraine. However, Kremlin spokesman Dmitry Peskov swiftly rejected the report, telling journalists that the account was “simply false” and denying any phone conversation between the two leaders took place.

According to the Post, Trump allegedly reminded Putin during the call of Washington’s significant military presence in Europe and expressed a desire for more discussions aimed at resolving the Ukraine conflict. Sources familiar with the report indicated that Trump had emphasized the need for peace talks to begin soon.

While Trump has previously stated during his campaign that he could end the war in Ukraine quickly—hinting at the possibility of direct talks with Putin—he has not provided details on how he would approach a peace agreement or what terms he would propose.

The Russian president has insisted that Ukraine must surrender large portions of its eastern and southern territories as a condition for peace talks, a stance that has been a point of contention throughout the conflict. The Post also reported that Trump briefly raised the issue of territorial concessions during the call.

Following Trump’s election, Ukrainian President Volodymyr Zelensky cautioned that any concessions to Putin, particularly over territory, would only embolden Russia and lead to further aggression. Zelensky has consistently opposed any territorial compromises in the ongoing conflict.
