In a day of emergency summits in Brussels, the Greeks were told their plans to release bailout cash provided a good basis for further negotiations this week.
Athens' plans, which included rises in GST and pension reforms, were the first real proposals in many weeks, said Donald Tusk, the European Council president.
Signs of a tentative breakthrough came after Jacob Lew, the US Treasury Secretary, telephoned Tsipras and Jeroen Dijsselbloem, president of the Eurogroup body of finance ministers, to highlight the need for urgency.
Pressure is mounting on the European Central Bank to keep Greece's troubled banking system alive, amid tentative hopes Greece will finally be granted the bailout money it needs to avoid a debt default next week.
The possibility of capital controls was raised at an aborted meeting of eurozone finance ministers, with Belgium's Finance Minister admitting EU officials had discussed the draconian measures to stop money bleeding out of the financial system.
Greek concessions
• Athens has tabled a number of measures, amounting to €8 billion over the next two years.
• They include plans to revamp the country's GST system.
• An overhaul of pension contributions is also planned.
• Other measures include reducing the threshold on corporation tax and cutting defence spending.
