What do we know about the US-Russia talks and the Ukrainian delegation's postponement of its trip to Riyadh?

The US-Russia talks represent the first formal discussions between senior US officials and Kremlin counterparts since Russia's invasion of Ukraine, marking a significant diplomatic shift. This meeting has slowed the pace of other diplomatic efforts, evidenced by President Zelensky postponing his delegation's trip to Riyadh. While immediate high-level summits between President Trump and Putin aren't imminent, these talks indicate a notable change from the previously united Western front that had been isolating Russia. This represents a tectonic shift in international relations, requiring more preparation and negotiation before potential leadership meetings occur.
