President Donald Trump’s hopes for a quick meeting with Russian President Vladimir Putin may be stalled.

Axar.az informs sources familiar with the matter told CNN that an expected pre-meeting between the world leaders’ key foreign affairs aides this week had been tabled, at least for now.

Trump said Thursday after a call with Putin that the two “agreed that there will be a meeting of our High Level Advisors, next week.”

“The United States’ initial meetings will be led by Secretary of State Marco Rubio, together with various other people, to be designated,” he wrote on Truth Social.

However, that anticipated meeting between Rubio and his Russian counterpart Sergey Lavrov has been put on hold for the time being, a White House official told CNN. It was not immediately clear why the meeting was no longer taking place this week, though one of the sources said Rubio and Lavrov had divergent expectations about a possible end to Russia’s invasion of Ukraine.

It was also not immediately clear what impact the tabling of the pre-meeting between Lavrov and Rubio would ultimately have on the anticipated Trump-Putin summit in Budapest, Hungary.

A source familiar with the matter told CNN, though, that officials felt after the Rubio-Lavrov call that the Russian position has not evolved enough beyond its maximalist stance. For now, the source said, Rubio is not likely to recommend the Putin-Trump meeting move forward next week, but Rubio and Lavrov could speak again this week.
