The meeting of eurozone finance ministers was the group's first opportunity to hear directly from the new leftist Greek government, which was elected on an anti-austerity platform. Greece wants to renegotiate the terms of its international bailout ahead of the expiration of the current agreement in late February.
There has been speculation that Greece could be granted extra time to hold new negotiations but German Finance Minister Wolfgang Schaeuble has poured cold water on that scenario. He told reporters at the Group of 20 meeting in Istanbul that such speculation was the stuff of fantasy.

The energy sector advanced 0.35 per cent even as oil fell $1.18 to US$48.84 a barrel as traders speculate on whether oil prices have bottomed. Oil prices have hit six-year lows, down 50 per cent from the highs of last summer amid a huge supply/demand imbalance on global markets.
However, there is little evidence that global oil production levels have shown any decline.
The latest data from the U.S. Department of Energy shows that supplies increased by another 4.9 million barrels last week, higher than the four million that analysts expected.
