French President Francois Hollande says Greece must stay in the eurozone but needs prove it can slash its budget deficit.
"Greece is in the eurozone and Greece must stay in the eurozone," Hollande said at a joint press conference with Greek Prime Minister Antonis Samaras at the Elysee palace on Saturday.
"But it still has to demonstrate the credibility of its program and the willingness of its leaders to go the whole way, while doing it in a way that is bearable for the population," he said.
Samaras was in Paris on the second leg of a trip to win more time for his country to meet a deadline to slash billions of euros from its budget.
He kicked off the two-day tour on Friday in Berlin with his crisis-wracked country's future in the 17-nation eurozone in the balance as its cash reserves dry up and a new injection of European funds hangs by a thread.
Germany's Chancellor Angela Merkel offered him a ray of hope at their meeting, stressing she wanted debt-burdened Greece to stay in the eurozone.
Hollande had the same message, and he echoed the German leader by saying the European Union would wait for a report due in October before deciding on any additional help.
That report on Greece's progress in implementing the reforms will be drawn up by auditors sent by the European Union, the International Monetary Fund and the European Central Bank.
As part of a 130-billion-euro ($A155 billion) bailout package from the EU and the IMF, Greece has committed to sweeping reforms and some 11.5 billion euros of cuts in 2013 and 2014.
But amid reports the budgetary hole is actually closer to 14 billion euros and a recession now in its fifth year, Samaras is thought to want a two-year extension.
He told reporters in Paris he was confident Greece would not be ejected.
"I also think that we can achieve our goals and our commitments, reduce deficits, our debt, complete the structural change we have begun," he said.
He pledged to stick to all promises to international creditors and said he was not asking for more bailout money, just "breathing space".
