Eurogroup chief Jeroen Dijsselbloem said Tuesday that talks with debt-strapped Greece were "flowing once again", but warned many details on a concrete solution still need to be fleshed out.
"The process is flowing once again. I can say that I'm cautiously satisfied," Dijsselbloem, who is also the Dutch finance minister, told local television station RTL Z during his weekly talk.
Greek Prime Minister Alexis Tsipras and German Chancellor Angela Merkel met in Berlin on Monday for talks in which both called for an end to the bitter recriminations the countries have traded in recent weeks.
"I hope the talks helped to improve the relationship between Germany and Greece a bit," Dijsselbloem said.
He urged Greece again to quickly provide more details to a list of changes which will be scrutinised by the Eurogroup bloc of finance ministers "and hopefully can be given the green light".
Greece is desperately seeking the last tranche of a 240-billion-euro ($260-billion) EU-IMF bailout, amounting to about seven billion euros, but Brussels is refusing until it first approves Athens's new package of reforms to its crisis-hit economy.
"As soon as we have an accord ... we'll be able to help with emergency loans again in the coming months," said Dijsselbloem, adding that Greece was for the time-being "still able to finance itself".
