According to Reuters, a Greek government official said that Tsipras told Lew that willingness and commitment is needed from all sides involved for a deal to be agreed. The Greek Prime Minister also noted that Greece has demonstrated this willingness.
“For an agreement to be viable it must respect fundamentally the Greek people and everything they have endured over the last five years,” Tsipras said during the phone call.
In the past few weeks, Lew and the United States government have urged for Greece and its creditors to find a solution. The Secretary of Treasury has also said that there could be geopolitical, aside from economic, implications of a Grexit.
