Around 6:00 p.m. local time, French President Nicolas Sarkozy received here German Chancellor Angela Merkel, European Council President Herman Van Rompuy, European Commission President Jose Manuel Barroso, President of the eurogroup Jean-Claude Juncker and Christine Lagarde, Managing Director of the International Monetary Fund (IMF) for the first meeting about Greece and the eurozone debt crisis.

This meeting and a later one following Sarkozy's working dinner with Chinese President Hu Jintao are unexpected arrangements to respond to Greek announcement of a referendum on European bailout plan to keep the country from default.

This move hit "all Europe" in surprise, Sarkozy said in one of the three statements in a row on Tuesday, announcing emergency meetings with eurozone leaders, foreign lenders of Greek debt and Greek prime minister as well as Greek Finance Minister Evangelos Venizelos, who is reportedly also shocked by the referendum announcement.
