June 5 will be the next crunch point in the Greek debt talks.
Greek government spokesman Gabriel Sakellaridis confirmed the government will pay salaries and pensions, however he said it would try its best to meet the June 5 deadline for a €1.6bn (£1.1bn) payment to the IMF.
"To the degree to which we are able to pay our obligations, we will pay our obligations. It's the government's responsibility to be in a position to pay all of these obligations," he said.
Sakellaridis also stressed that it urgently needs aid to be able to do so.
Earlier this week Voutsis' warned that Greece couldn't affords its 5 June payment to the IMF saying "this money will not be given and is not there to be given".
Greece has been locked in high stakes talks with its "troika" of creditors - the European Union, the European Central Bank and the IMF - over a list of economic reforms since February.
The country wants to unlock billions of euros of credit due under its €240bn (£170bn) bailout agreement, as it hasn't received any tranches of loans since last August.
However progress has been slow, and there are concerns that the cash-strapped country could default on its €320bn (£227bn) debt before it reaches an agreement, with unknown consequences for the euro area.
