The Ukraine aide to the US president-elect, Keith Kellogg, has delayed his scheduled visit to Kiev until after Donald Trump‘s inauguration, as reported by Reuters on Tuesday. The retired lieutenant general had originally intended to meet with Ukrainian leaders in early January.

The reasons for this postponement remain unclear, and no new date for the visit has been established, according to the news agency.

Bloomberg noted last month that Kellogg was also receptive to the idea of meetings in Moscow if an invitation were extended. This trip would primarily aim to gather information rather than pursue specific policy objectives, as reported by the outlet. However, Reuters did not mention any plans regarding Moscow in its report on Monday.

Kellogg has previously voiced concerns regarding the ongoing Ukraine conflict, remarking that “this has become a war of attrition that’s going to kill a whole generation of young men.”

Trump has consistently asserted that he could resolve the conflict within 24 hours of taking office. He has also criticized outgoing President Joe Biden’s choice to allow Kiev to use US-supplied missiles to strike deep into Russia, labeling it a perilous escalation.

Furthermore, Trump has indicated that he might withdraw aid to Ukraine if the country does not seek a peace agreement. He suggested last month that he anticipates Vladimir Zelensky might need to consider certain territorial concessions as part of a potential peace settlement.

Moscow has consistently expressed its willingness to engage in dialogue regarding Ukraine without any preconditions, referencing the preliminary agreements established in Istanbul in 2022 and the current circumstances on the ground. President Vladimir Putin has identified several prerequisites for a peaceful resolution, including the withdrawal of Ukrainian forces from the Donbass region, as well as from Kherson and Zaporozhye, in addition to Ukraine renouncing its aspirations to join NATO.

A peace proposal co-authored by Keith Kellogg and presented to former President Trump earlier this year suggests freezing the conflict along the existing front lines and imposing a ten-year moratorium on Ukraine’s NATO membership. Russian Foreign Minister Sergey Lavrov has remarked that Kellogg should take a more in-depth look at the complexities surrounding the Ukrainian situation.
