Yanis Varoufakis has called for an end to the “toxic blame game” between Greece and Germany.
The finance minister made the call as Greece prepares to finalise its list of economic reforms to present to its international creditors.
The reforms are needed to unlock a new tranche of bailout cash for Greece, which could run out of money in weeks.
Mr Varoufakis said that finger-pointing between Germany and Greece would only aid Europe’s enemies.
Athens and Berlin have been engaged in a bitter war of words as the Greek government seeks to renegotiate the terms of its bailout.
German finance minister Wolfgang Schaeuble has publicly expressed his anger, claiming last week that Greece “has destroyed all trust”. He also acknowledged that Greece could “accidentally leave the eurozone”.
Writing in the German business newspaper Handelsblatt, Mr Varoufakis said that tensions between the two countries “must stop”, adding: “Only then can Greece, with support of its partners, focus on implementing effective reforms and growth-orientated policy strategies.”
Greece submitted plans to the European Union, International Monetary Fund and the European Central Bank on Friday night that it says will raise some €3bn (£2.2bn) in state revenues.
The measures includes plans to combat tax evasion, more privatisations and higher taxes on alcohol and cigarettes, but do not include any “recessionary measures” such as wage and pension cuts.
However, the measures in their current form do not appear to have been specific enough to win the approval of the lenders, formerly known as the “troika”.
Talks continued over the weekend and the lenders said it could take several days until a proper list of measures was ready.
One senior eurozone official told Reuters: “As they stand, they lack detail and much more technical work will be needed for them to flesh them out into something sufficiently comprehensive and credible to be put to the Eurogroup [of finance ministers].”
Greece faces a crunch point on 9 April when it is due to repay a tranche of funds to the IMF.
