As there will now be another meeting of the eurozone finance ministers next Monday (November 26), the Greek Prime Minister Antonis Samaras has postponed a visit to the wealthy Gulf state of Qatar, which was due to happen next week. "The prime minister will stay in Athens to coordinate things," spokesman Simos Kedikoglou told Reuters. Samaras was due to meet Qatar's emir and prime minister as well as top officials from Qatar's sovereign wealth fund to discuss investment in the country's recession-mired economy. The German Finance Minister Wolfgang Schaeuble also spoke after the meeting. He told lawmakers at a closed-door session that Greece's lenders remained divided over how to fill a €14bn hole in the country's finances through 2014 and how to define debt sustainability for the eurozone's weakest link, participants told Reuters. Schaeuble met members of parliament on Wednesday morning to explain the failure of the negotiations. One participant said Schaeuble had told members of his conservative party that lenders had failed to resolve the issue of whether 2020 or 2022 would be used as a benchmark for Greek debt sustainability. The source said Schaeuble had explained that the ECB believed Greece could raise €9bn itself by issuing short-term debt. Another Christian Democrat lawmaker said the minister had told participants that a debt buyback could be part of the solution.
