Greek finance minister Yanis Varoufakis will travel to Washington to meet with International Monetary Fund Managing Director Christine Lagarde and unspecified US Treasury officials, the Greek government has announced.

Varoufakis will meet Lagarde Sunday evening and the Treasury officials Monday.

Greece is locked into difficult negotiations with its creditors over its bailout program and this has delayed the disbursement of a 7.2 billion euro ($7.9 billion euros) aid tranche and led to a cash crunch, forcing the government to tap into reserves to meet its obligations.

Earlier Saturday, deputy finance minister Dimitris Mardas told TV station Mega that Greece has the funds to repay a 450 million euro ($493.8 million) loan instalment to the IMF on April 9, but it is up to the government to decide whether to pay.
