DRESDEN, Germany (AP) Finance ministers from the Group of Seven wealthy democracies heard a sharp call from U.S. Treasury Secretary Jacob Lew to find agreement on more financial help for Greece.

Lew said that a further delay in Europe's six-month old talks with Greece was "courting an accident" such as a Greek default or messy exit from the euro, which could have unpredictable effects on the global and European economies.

Lew said Friday at the end of meetings in Dresden, Germany: "Too much time has been spent unproductively." The ministers at the meeting officially discussed more long-term projects such as making sure multinational companies pay all their taxes, but Greece overshadowed the talks.

Lew said "the challenge is to treat this week as a week in which there has to be progress."
