Greece on Tuesday floated proposals to ease the economic pressure generated by its massive foreign debt, boosting stock markets as hopes rose for a deal with its European Union partners.
Italian Prime Minister Matteo Renzi said he believed an accord on the debt terms was possible, and promised Greek counterpart Alexis Tsipras, whom he met in Rome, of Italy's support in trying to achieve it.
"There has to be change in Europe," Tsipras said. "We have to put social cohesion and growth before the policies of poverty and insecurity."
Renzi echoed the call for more growth-orientated policies but pointedly steered clear of any comment on the detail of Greece's proposals, which he said would be discussed by EU leaders next week.
"The world is calling on Europe to invest in growth, not austerity," Renzi said, before joking that the election of Tsipras was a "blessing" because it ensured he was no longer Europe's number one "dangerous lefty".
The press conference finished on a light-hearted note with Renzi presenting Tsipras with an Italian tie.
Tsipras -- whose fondness for open-necked shirts is often highlighted as a badge of his anti-establishment beliefs -- promised to wear it when "we finally find a viable solution."
- Debt swaps not haircuts -
Greek Finance Minister Yanis Varoufakis is pushing the idea of debt swaps that would avoid the need for creditors to accept 'haircuts' on the country's 315-billion-euro ($361-billion) foreign debt, while easing the monthly financing burden on the Athens government.
He said Greece's ideas would be put to eurozone finance ministers next week ahead of the summit of EU leaders.
Varoufakis heads to Frankfurt Wednesday for talks with European Central Bank officials, who were reported Tuesday to be opposing a pivotal part of his plan: a request for bridging finance needed to keep the country solvent until June.
According to the Financial Times, the ECB's opposition could lead to Athens running out of cash at the end of February -- a suggestion that may spook markets as much as Tuesday's developments cheered them.
The Greek minister will have another tricky encounter on Thursday, when he will meet Germany counterpart Wolfgang Schaeuble in Berlin in what will be a key test of whether his proposals have any chance of being accepted by the EU's leading powers.
- Athens stocks soar -
The Greek initiative was interpreted by markets on Tuesday as reducing the likelihood of any unilateral debt cancellation, which would entail a risk of reigniting the kind of financial turmoil that has severely damaged leading economies since 2007.
Led by the Athens bourse, which closed up more than 11 percent, stock markets across Europe rose on the news, as did Wall Street.
"After a week of trading insults and threats it looks like the eurozone paymasters and the new Greek government are finally ready to compromise," said Kathleen Brooks, research director at trading site Forex.com.
The Greek government denied the debt swaps proposal represented a climbdown from election promises to force a renegotiation of its debt terms.
"If we need to use euphemism and the tools of financial mechanisms to get Greece out of its debt-slavery, we will do it," a spokesman said.
The Greek plan would involve swapping some of the country's current bonds for new ones under which repayments would be linked to economic growth rates.
Greek bonds owned by the European Central Bank would become "perpetual", or open-ended, removing the need to make regular repayments at fixed intervals.
- Germany unimpressed -
German Chancellor Angela Merkel was non-committal about the Greek proposals. "It is clear the Greek government is still establishing its position," she said. "We await their proposals and there will be time enough to discuss them."
Privately, German officials said there was "little room for manoeuvre" on the debt conditions.
Greece's debt is worth 1.75 times the country's entire annual economic output. Because of severe spending cuts, the government now raises substantially more in taxes than it pays to fund services, but that surplus is more than wiped out by the cost of servicing the debt.
US President Barack Obama on Sunday appeared to side with Greece by warning of the dangers of "squeezing" an economy in the grip of recession.
- Next stop Paris -
Tsipras has dismissed the "troika" system monitoring Greece's economy -- the International Monetary Fund, European Commission and ECB -- as lacking legal status, and blames Germany for driving the tough austerity programmes that his radical left government has pledged to end.
But he also says Greece has no intention of not meeting its outstanding obligations to the bailout creditors.
The new premier is due in Brussels on Wednesday and will also visit Paris in search of support from France, the eurozone's second-biggest economy and, like Italy, a critic of EU 'austerity'.
