Yanis Varoufakis has met with IMF officials in Washington during the weekend.

"We are intent upon reforming Greece deeply, this is our promise to the Greek people, so having an opportunity to discuss the reform program here at the IMF with the Managing Director is an excellent step towards that direction."

He also stressed that the Greek government plans to improve the efficacy of negotiations with its creditors.

IMF Managing Director Christine Lagarde says she welcomes the confirmation.

She says efforts in Athens and talks with teams in Brussels over the terms of Greece's bailout will resume promptly.

Greece is fast running out of cash, but its EU and IMF lenders have frozen bailout aid until the government reaches an agreement on a package of reforms.

Last week, the country presented a new package of reforms in hopes of receiving some international funding.

But the proposal has not yet received approval from Greece's EU and IMF lenders.

The delay of about 7.2 billion euro pledged to Greece has forced the government to dip into reserves to meet its obligations.
