The United States is privately calling on Ukraine to demonstrate its willingness to negotiate with Russia, the Washington Post reports.

The newspaper, citing unnamed sources, wrote that the call from U.S. officials was not aimed at pushing Ukraine to the negotiating table, but a calculated attempt to ensure Kyiv's support from other countries.

U.S. and Ukrainian officials acknowledged that Ukrainian President Volodymyr Zelenskiy's ban on talks with Russian President Vladimir Putin has raised concerns in parts of Europe, Africa and Latin America, where the impact of the war on food and fuel costs is most acute," the Post reports.

Ukraine fatigue is a real concern for some of our partners, the Post quoted an unnamed U.S. official as saying.

Zelenskiy signed the Oct. 4 edict, officially declaring the prospect of any negotiations with Putin "impossible" but leaving the door open for talks with Russia.
