Talks continued on Tuesday, with Greece's Deputy Prime Minister Yannis Dragasakis and Deputy Foreign Minister Euclid Tsakalotos—who is now heading negotiations with Greece's lender—meeting the head of the European Central Bank, Mario Draghi in Frankfurt.
Meanwhile, Greek Finance Minister Yanis Varoufakis looks set this week to repeat the whirlwind tour of European capitals that he took shortly after taking up the post in February.
Varoufakis traveled to Paris on Tuesday for talks with French counterpart Michel Sapin Tuesday, before heading to Brussels for talks with Moscovici.
He will then return to Paris for talks with French Economy Minister Emmanuel Macron, according to the Greek newspaper To Vima, before heading to Rome to meet Italy's Padoan on Wednesday.
