In a joint statement issued after the meeting, the leaders reiterated their “unwavering support” for Ukraine and outlined conditions they said were necessary to secure a just and lasting peace. Five conditions for peace First, the leaders called on Russian President Vladimir Putin to agree to an immediate and comprehensive ceasefire. Second, they said the current front line should serve as the basis for negotiations, stressing that international borders cannot be changed by force and that Ukraine’s sovereign right to choose its security arrangements and alliances must be respected. Third, they said Ukraine must receive robust and legally binding security guarantees once a ceasefire takes effect. Those guarantees would build on commitments agreed in Berlin in December 2025 and Paris in January 2026 and include the deployment of a multinational force in Ukraine.
