Greece's international lenders have agreed the latest instalment of a loan to the debt-stricken country, but say Greece must make "an extra effort" to address its deficit next year.
In May, the EU and the IMF agreed a rescue package worth up to 110bn euros ($145bn; £91bn) over three years.
Greece will now receive the third tranche of that loan, worth 9bn euros.
But the government has had to agree new measures "to broaden tax bases and eliminate wasteful spending".
Greece is aiming to reduce its deficit to 7.5% of GDP in 2011 from the 15.4% it stood at last year.
Staff teams from the European Union, European Central Bank (ECB) and International Monetary Fund have now concluded their second review of Greece's economic programme.
In a joint statement, they said that the programme remained "broadly on track" and they expected the Greek economy "to begin turning around" in 2011.
They regarded as impressive the savings that the Greeks had made during a deep recession.
But the statement went on: "At the same time, data revisions for 2009 and weaker-than-projected revenue collection mean that an extra effort will be needed to meet the deficit target of 7.5% of GDP in 2011, which the government has reaffirmed."
The international team believes that Greece is at a crossroads, BBC Athens correspondent Malcolm Babrant said, and needs to continue to make profound structural reforms.
In particular they want to see better tax collection as well as cuts in the national health service and the loss-making state-owned companies such as the railways.
The IMF believes these organisations are overstaffed and that in some cases employees are overpaid, our correspondent said.
IMF representative Poul Thomsen said there would have to be job cuts, but he hoped that they could be achieved by natural wastage, by replacing one of every five people leaving voluntarily.
The next review of Greece's progress is scheduled for February.
The Greek government has made efforts to cut its spending this year, which has led to violent protests and strikes throughout the country.
Last week, the government unveiled an austerity budget for 2011 which aims to cut health and defence spending, and increase the sales tax on most retail items.
On Monday, the Greek Ministry of Finance said the country's budget deficit for the year to October stood at 17.33bn euros.
This was down 30.2% on the same period in 2009, but below the targeted 32.2% for the ten months as published in the budget.
Greece's borrowing costs have risen sharply in recent months - suggesting investors still have concerns about the government's ability to pay its debt - despite the EU-IMF bail-out.
In May, the yield on Greek 10-year bonds stood at about 7.75%. It is currently 11.82%.
