Mark Carney, the head of Canada's central bank, called for "ray ban sale" the problem by more than doubling the current 400 billion euro rescue fund to 1 trillion euros, an amount that would equal $1.35 trillion.

The IMF panel, which sets policy for the 187-nation lending institution, wrapped up discussions at its annual meeting with a statement pledging to work decisively and in a coordinated way to deal with Europe's debt crisis.

The United States was represented at the meeting by Geithner and Federal Reserve Chairman Ben Bernanke.

The statement was similar to pledges of increased support made Thursday by finance officials from the Group of 20 major world economies. Both statements were short on specifics.

The IMF statement said the fund stood ready to back further efforts to deal with the cheap ray bans bailout support for Greece, Portugal and Ireland.

"Today, we agreed to act decisively to tackle the dangers confronting the global economy," the IMF's managing director, Christine Lagarde, told reporters.。
