On March 29, 2022, after one month of war, direct Ukraine-Russia negotiations are held in Istanbul. These are the most advanced talks since invasion began.

Participants: Ukrainian (Podolyak, Arakhamia) and Russian (Medinsky) delegations. Turkish presence (Erdogan) as mediator.

Ukrainian proposal: Permanent neutrality of Ukraine with security guarantees from USA, UK, France, Turkey, Germany, Italy, Poland, Canada. No NATO, but guaranteed military assistance in case of aggression.

Russian demands: Recognition of Crimea, independence of Donbass, demilitarization of Ukraine, no foreign troops, no military exercises without guarantors' consent.

Crucial moment: Russia announces reduction of military operations near Kyiv "to build confidence". On March 30, Russian troops begin withdrawal from northern Ukraine.

Why they failed:
- April 2: Discovery of Bucha massacre (hundreds of civilians killed by Russians)
- Ukraine breaks off negotiations: impossible to negotiate after war crimes
- Boris Johnson visits Kyiv (April 9), encourages resistance
- Discovery of atrocities in Irpin, Mariupol

Debate: Some argue agreement was close. Others say Russia used talks to buy time and reposition troops for Donbass offensive.

Never resumed: Istanbul remains last serious attempt at direct negotiation before 2025.
