The German Finance Ministry said on Saturday it was not aware of any agreement by euro zone members to provide a multi-billion euro bailout package for heavily indebted Greece.
We are not aware that this is being planned, a ministry spokesman said, adding that Greece had not requested any aid.
Greece is implementing its (savings) program and we expect that it will manage it alone, he said.
Earlier on Saturday, the Guardian newspaper quoted a senior European Commission official as saying the 16 euro zone members had agreed on coordinated bilateral contributions in the form of loans or loan guarantees to Greece if Athens was unable to refinance its debts and asked the European Union for help.
