The US is refusing to co-sponsor a draft UN resolution marking three years since Russia's invasion of Ukraine that supports Kiev's territorial integrity and condemns Russian aggression, three diplomatic sources told Reuters.
The move appears to reflect a rift between Ukrainian President Volodymyr Zelenskiy and US President Donald Trump, who is trying to quickly end the war in Ukraine and whose team has held talks with Russia without Kiev's involvement.
The dispute is a major political crisis for Ukraine, which has used tens of billions of dollars in US military aid agreed under the previous US administration to withstand Russia's invasion and has also benefited from diplomatic support.
The draft resolution for the UN General Assembly condemns Russian aggression and reaffirms a commitment "to the sovereignty, independence, unity and territorial integrity of Ukraine within its internationally recognized borders."
"In previous years, the United States has consistently co-sponsored such resolutions in support of a just peace in Ukraine," one of the sources told Reuters on Thursday, who like others requested anonymity to discuss sensitive issues.
