Russia and Ukraine have so far held two rounds of peace talks on May 16 and June 2. They have agreed to exchange seriously ill and young prisoners of war, discuss a possible ceasefire, and exchanged documents outlining their perspectives on conflict resolution.

The same day, Ukrainian President Volodymyr Zelenskyi expressed readiness for a leaders' summit between himself, Russian President Vladimir Putin, US President Donald Trump, and Turkish President Recep Tayyip Erdogan.
