Talks to ease the conflict over breakaway regions in Georgia are suspended until November, after diplomats failed to get Russia and Georgia to agree on who was allowed to take part.
The sticking point was whether representatives from South Ossetia and Abkhazia should be allowed to participate and in what format.
Russia and Georgia fought a five-day war in August and are still at odds over the two breakaway Georgian provinces. Moscow recognises them as independent states under its protection.
The European Union, United Nations and Organisation for Security and Co-operation in Europe organised the meeting, to deal with compliance with the ceasefire, security issues and the return of internally displaced persons and human rights.
An EU special envoy Pierre Morel said new talks had been provisionally set for 18 November in Geneva.
In Brussels, Georgian President Mikheil Saakashvili blamed Russia for the failure of the talks. Russian denied this.
The United States blamed the impasse on representatives of the breakaway regions, saying they want the same status as the national delegations.
Russian troops leave buffer zones
Last week, Russian troops left their self-imposed buffer zones around Abkhazia and South Ossetia, in accordance with the French-brokered ceasefire deal.
But Moscow plans to keep nearly 8,000 soldiers in the two rebel regions.
In a separate development, the International Court of Justice ordered Georgia and Russia to protect civilians from ethnic discrimination in South Ossetia and Abkhazia - another Georgian rebel region.
Tbilisi had asked the court to order Moscow to protect ethnic Georgians in the two regions, but judges at the UN's highest court ruled that all civilians were at risk.
