"We stressed that before the next disbursement Greece clearly and credibly should demonstrate its commitment to fully implement the program -- and 89 prior actions from March should be implemented by the 18th of October at the latest," Eurogroup Chairman Jean-Claude Juncker said on Monday at the close of talks with eurozone finance ministers in Luxemburg, AFP reported.
IMF chief Christine Lagarde, who also attended the eurozone finance ministers meeting, said, "On Greece more work needs to be done… Acting means acting, not just speaking."
On Friday, Greek Prime Minister Antonis Samaras said that his country could not take more bitter medicine and if the next disbursement of 31.5 billion euros from a 130-billion second package of loans for the country did not arrive soon, the government will run out of cash next month.
The warning by Greece's bailout creditors came a day before German Chancellor Angela Merkel visits Greece to hold talks with Prime Minister Samaras and President Carolos Papoulias.
Merkel is likely to face angry protests in a country where many blame Germany for the Greek government's draconian austerity measures.
Public Order Minister Nikos Dendias appealed to protesters on Monday to "protect the peace, and above all our country's prospects and our international image."
Some 7,000 police officers will be deployed across Athens on Tuesday to maintain security during Merkel’s stay.
Greece has been at the epicenter of the eurozone debt crisis and is experiencing its fifth year of recession, while harsh austerity measures have left about half a million people without jobs.
