Greece's debt to the troika of creditors comprising the European Union, the European Central Bank and the International Monetary Fund stands at about $270 billion. In February, Athens and Eurozone finance ministers reached an agreement to extend Greece's bailout for four months in exchange for Athens’ promise to implement a list of reforms.
In the letter, a copy of which was obtained by the Financial Times, Tsipras criticized the Eurozone ministers’ refusal to issue short-term debt to Greece before Athens adopts a new round of economic reforms.
The letter, dated March 15, came before Merkel invited Tsipras to hold a one-on-one meeting in Berlin on Monday evening.
Germany is one of Greece’s major creditors within the European Union. Athens total debt is estimated at $345 billion, with $22.5 billion in interest payments required this year.
