Greece will meet all of its obligations to its creditors in full, Prime Minister Alexis Tsipras pledged on Sunday in remarks reported by the Athens-based newspaper Realnews, but his government would not accept any "nonsensical demands."
Tsipras did not specify what those nonsensical demands might be.
He said that by sticking to the austerity programme and implementing the remaining reforms, Greece would emerge from its economic crisis in 2016.
Tsipras was confident that he would be successful in getting a pension reform plan through parliament, saying his majority of 153 out of 300 lawmakers was "absolutely solid."
He dismissed media speculation about a multi-party government in the event of his left-right coalition falling apart as "midsummer night's dreams."
The parliament in Athens has to pass several controversial bills in the coming weeks as a precondition for Greece's receiving more support from its international creditors.
The most controversial plans are for pension reforms and additional taxes on farmers.
