What the Istanbul talks produced on 4 June 2025
Summary
A look back at a prisoner exchange agreement and an exchange of ceasefire proposals between Russia and Ukraine.
What did the latest round of Russia–Ukraine talks actually deliver? By 4 June 2025, two days after the delegations met in Istanbul, Turkey, the clearest result was an agreement on a prisoner of war exchange.
Officials confirmed the terms: all sick and severely wounded prisoners of war would be exchanged, along with those younger than 25. The categories were defined by condition and age, which set the scope of the swap.
The two sides also exchanged ceasefire proposals during the negotiations. That was a procedural step: each delegation put its own text forward, and the talks were not reported to have produced a joint ceasefire arrangement.
The positions behind the papers
The proposals landed against a long-standing divide. Russia's president, Vladimir Putin, has sought recognition of all occupied land as Russian, guarantees that Ukraine will never join NATO, curtailment of Ukraine's military and the lifting of sanctions. Ukraine's president, Volodymyr Zelenskyy, has sought a ceasefire, full withdrawal of Russian troops, the return of prisoners and kidnapped Ukrainian children, prosecution of Russian leaders for war crimes, and security guarantees.
One item overlaps: the return of prisoners. That is where the Istanbul round produced a concrete agreement, while the broader demands remained far apart.
The June exchange deal therefore stood as a humanitarian outcome of a negotiation whose political questions were still open.
