The International Monetary Fund (IMF) will not participate in the funding of Greece’s bailout program if there’s no “reliable strategy for the sustainability” of the country’s debt, the fund’s spokesman William Murray said on Thursday, during a regular press briefing.

The agreement opens the way for discussions on the sustainability of the Greek debt, the president of the Eurogroup Jeroen Dijsselbloem‏ posted on Twitter.

IMF BoD approved the report on the Greek economy and the Greek debt sustainability, which retains the gap between the fund and the European creditors to Greece.
