Talks between Greek Prime Minister George Papandreou and German Chancellor Angela Merkel, due to be held here on Tuesday, are expected to focus on the Greek economy's course and the preparation of an European Union informal summit on March 11.

"Greece's economic situation, as well as the important measures that are being taken by the country in the framework of its public finances' restructuring programme, will be discussed," German government spokesman Stephen Zeibert said here on Friday.

In this respect, Zeibert underlined the "German support towards the great reform efforts that Greece is making."

Papandreou will also be meeting with German Foreign Minister Guido Westerwelle, the German Social-Democratic Party (SPD) leader Zigmar Gabriel, the president of SPD's parlia-mentary group and former foreign minister Frank-Walter Steinmeier and the Green party co-president Claudia Roth.
