The head of the IMF has said a crucial meeting of Eurozone finance ministers next week will be key to getting Greece "back on its feet".
International Monetary Fund director Christine Lagarde made the comments as she cut short her visit to Asia to attend the talks.
She told reporters in Manila that "it's not over until the fat lady sings".
Eurogroup president Jean-Claude Juncker has said he hoped the meeting on Tuesday would clear the way for a payment of €31bn that Greece desperately needs to avoid default.
