Japan's finance minister said on Friday that a "strong message" needed to be sent over the eurozone debt crisis at the G20 summit next week.

Jun Azumi said he was ready to join with US Treasury Secretary Timothy Geithner in pressing Europe to take fresh measures to tackle the turmoil.

"During the G20 meeting, a strong message needs to be sent to the world regarding this issue of the European debt crisis," Azumi told reporters.

"Secretary Geithner appears to be calling for various specific steps" from European policymakers, he added.
