TOKYO - A senior official at Japan's Ministry of Finance said on Wednesday that finance ministers from the Group of Eight nations may discuss exit strategies from extraordinary policy steps taken to combat the global economic crisis.

"There are indicators that show bright signs in each country, but the outlook remains unstable," the official added.

But the official said finance ministers are unlikely to single out the issue of rising bond yields at this weekend's meeting.

"I don't consider rising bond yields as a factor behind the unstable outlook for the economy," the official added.

Finance ministers from the Group of Eight leading world powers gather in Lecce in southern Italy on Friday and Saturday to take stock of efforts to combat the global economic crisis, agreed at a G20 summit in London in April.
