Five-party negotiations on the Cyprus problem ended without resolving key disputes, but discussions will continue under UN guidance. Greek Cypriot President Nicos Christodoulides and Turkish Cypriot leader Ersin Tatar participated, with no agreement on reopening crossing points. UN Secretary-General Antonio Guterres noted some progress and scheduled further meetings. Key unresolved issues include opening transit points and solar power installation. The talks introduced new measures for civil society participation and environmental monitoring. A trilateral meeting is set for September.
