Taoiseach Enda Kenny has told a meeting of centre-right parties from around the world that if Ireland is to build on recent stability, there must be growth in the euro zone.
He was speaking in Rome at a meeting of the Centrist Democrats International group.
This is affiliated with the European People's Party, of which Fine Gael is a member.
Earlier, Mr Kenny met the Italian Prime Minister Mario Monti.
Mr Kenny said Mr Monti is very supportive of ensuring that Ireland's banking debt is restructured in line with a decision of EU leaders in June.
Mr Kenny said, however, that an October target date for achieving a banking debt deal was now unrealistic.
The two men also discussed Ireland's upcoming Presidency of the European Council next year and how to secure economic growth against a backdrop of stagnation and recession.
Meanwhile, the leaders of Italy and Greece have insisted on the "absolute need" to preserve the euro zone, as Greek politicians struggle to put together an austerity package critical to the country's financial survival.
Italy's Premier Mario Monti met Greek Prime Minister Antonis Samaras on the sidelines of a political conference in Rome today.
A statement from Monti's office said the two leaders reiterated their conviction of "the absolute need to safeguard the integrity of the eurozone, stabilise markets and proceed in the process of European integration."
Samaras' coalition government has yet to agree on details of €11.5 billion worth of cuts so the country can get bailout cash. Without the money, Greece might default and abandon the euro.
