Debt inspectors from the EU, European Central Bank and IMF, known as the troika, met in Athens with member of the coalition government and leader of the socialist party, Evangelos Venizelos, today.
The inspectors have remained in Greece to try to finalise a major new package of budget savings.
Lenders are demanding these savings as a condition for continued bailout funds which the country needs to avoid getting forced out of the eurozone.
The troika - originally supposed to have left Greece by the end of July - is to issue a report on Athens' progress in September.
Finance Minister Yannis Stournaras told journalists on Monday that the government is still working to precisely identify what kinds of spending cuts to include in the new €11.5 billion package for 2013-14, although the three coalition partners have signed off on the bulk of the plan.
If Athens loses its rescue loan lifeline from its European partners and the International Monetary Fund (IMF), it will be unable to pay state salaries and pensions or service its huge debt.
That kind of disorderly bankruptcy would likely force Greece to abandon the euro and return to a devalued form of its old drachma currency.
George Tzogopoulos, a researcher at the Hellenic Foundation for European and Foreign Policy, said Greece was not doing enough to convince its creditors that it is prepared to move on with structural reforms.
"What we need now is that the government first goes on with privatisations and additional measures regarding structural reforms and then to ask for more time," he said.
A government spokesperson said the country was fighting to regain the country's international credibility after Greece repeatedly missed fiscal targets set under bailout agreements.
As part of its austerity efforts, Greece has achieved a remarkable reduction of its budget deficit from 15.8% in 2009 to 9.1% last year.
However, the country is considerably off-target in other areas of reform.
Athens largely blames this on a deeper-than-anticipated recession, which could see its economic output fall by more than 7% this year.
That would bring the total economic contraction over the past five years to a crippling 20% - which Samaras has likened to the Great Depression in the US.
Near-bankrupt Greece is fast running out of cash while it waits for its next installment of aid from international lenders, a deputy finance minister has said.
This has sounded the alarm on the country's precarious financial position.
Greece's European partners have repeatedly promised the country will be funded through August, when it must repay a €3.2 billion bond, but the details of the funding have yet to be disclosed.
