What significant diplomatic developments are occurring regarding the Ukraine conflict?

The EU is preparing its 16th round of sanctions against Russia, which will be finalized at a meeting of EU foreign ministers on Monday, coinciding with the third anniversary of Russia's invasion of Ukraine. Meanwhile, attention is focused on a potential Putin-Trump meeting that the Kremlin says may happen later this month. Moscow has characterized this meeting as the first step towards resolving the conflict, though they've cautioned that achieving a comprehensive peace deal could take considerable time.
