German Finance Minister Wolfgang Schaeuble said there was no reason for euro zone finance ministers to make any decision on financial aid for debt-ridden Greece when they meet on Monday.
"There are always rumours, especially ahead of such meetings," he told German newspaper Bild, in an interview published on its online service on Sunday.
"But there are no new factors. Therefore, there is no reason to take decisions on financial aid on Monday."
Schaeuble echoed comments made on Saturday by French Economy Minister Christine Lagarde, who said it was premature for a decision to be made on aid.
Finance ministers from the 16 countries using the euro, the Eurogroup, are set to meet on Monday in Brussels to discuss the Greek debt crisis and the country's progress with the austerity programme needed to regain the confidence of financial markets.
Schaeuble, who was admitted to hospital last month for a planned operation, said he could be discharged in time to participate in the Eurogroup meeting on Monday afternoon.
A European Union source told Reuters that Eurogroup finance ministers are likely to agree on Monday on a mechanism for providing Greece with financial help but leave out any figure since Athens has not asked for aid.
But British newspaper The Guardian had said on Saturday that aid to be made available to Greece could reach 25 billion euros. Greece's borrowing needs for the whole of 2010 total 53.2 billion ($73.2 billion) euros.
Schaeuble said the Eurogroup needed to solve the Greek crisis itself, "otherwise the United States and China will no longer take us seriously".
The finance minister, who has called for the creation of a European Monetary Fund which could offer help to euro zone states facing bankruptcy, said such a fund could not solve the problems currently facing Greece.
"We have to solve this crisis with the existing instruments and the Greek government deserves great respect for its savings efforts," he said.
Schaeuble added that the resolution of the Greek crisis would be "decisive in setting the course for the stability of the euro".
