They will face a difficult task in trying to smooth ties after a tumultuous few weeks. Germany is clearly alarmed at the prospect of Greece not honoring past financial pledges and triggering a crisis that could force it out of the euro zone.
"They have destroyed all trust once again," Schaeuble told a panel discussion in Berlin on Monday, saying he had no clue as to how Athens intended to solve its problems. "Among my colleagues at the international institutions I can find no one who can tell me how that might actually work," he said.

The unexpectedly low figure means Greece looks set to miss a key target of its bailout program.
Although Greece secured in February a four-month extension to its bailout, the accord did not give Athens access to funds already pledged to it from the euro zone and the International Monetary Fund, leaving it facing a cash crunch.
No debt relief

"Whatever obstacles we may encounter in our negotiating effort, we will not return to the policies of austerity," Tsipras told daily Ethnos in an interview published on Monday, blaming budget rigor for Greece's record high unemployment.
Presenting a united front with Germany, the EU financial affairs chief Pierre Moscovici said on Monday that Greece could not expect to see any of its loans written off.
"Debt has to be repaid, that's clear. Debt cannot be wiped out. There will be no haircut, no debt relief," Moscovici said in Berlin, urging Greece to implement economic reforms.
