The latest attempt by the Greek government to strike a chord with its creditors comes after a rollercoaster two weeks in power in which the Greek government has appeared both unrepentant over scrapping austerity measures.
While the new Greek government appeared to try to strike a more conciliatory note with its euro zone neighbors last week, touring European capitals in an effort to drum up support for a new debt deal with lenders. This weekend, however, there seemed to be a change of tack with a return to more bullish, anti-austerity rhetoric.
Prime Minister Alexis Tsipras reiterated that he would not extend the country's current bailout and would not accept more loans while finance minister Varoufakis said the euro zone would collapse "like a house of cards" if Greece left the single currency.
Adding to the pressure, Greece's defense minister said Tuesday that the country could always look elsewhere for financial aid, adding "It could the United States at best, it could be Russia, it could be China or other countries," he said.
Defending the Greek government against accusations that it was trying to "blackmail" Europe into agreeing to its bailout demands, Dimitrios Papadimoulis, Syriza member of the European Parliament (MEP) told CNBC
"We don't want to blackmail anyone, but we don't want to be blackmailed by anyone," he told CNBC Europe's "Squawk Box" Tuesday.
German Chancellor Angela Merkel said on Monday that she would wait for Greece to make a sustainable proposal to repay its debts and other reforms and then discuss what to do next, Reuters reported.
The growing tension has not gone unnoticed elsewhere with equity markets in the U.S. and Asia trading lower on Greek concerns on Monday.
On Sunday, U.S. Treasury Secretary Jack Lew told CNBC that "everybody's got to tamp down the rhetoric a little bit."
"The heat has to come down a little bit in the conversation… the sooner that happens, the better…there needs to be a conversation where Greece and all of the parties that it's engaged with, look for a practical, pragmatic path forward-- which I think is in everybody's best interest," Lew said in an interview broadcast Monday.
The Canadian Finance Minister Joe Oliver also told CNBC Monday that the Greek government "would have to back off a bit from its public rhetoric and they're going to have to make significant, continued sacrifices." He did not believe that debt forgiveness was on the cards.
Sapin, meanwhile, said that the Greeks needed to use more diplomatic language in power.
"Words have a meaning and a strength. And you can't talk the same way when you are finance minister or prime minister than when you were just a candidate."
