The government may purchase additional rescue bonds to be issued by Europe's bailout fund to help cure the volatile situation triggered by the Greek crisis, Finance Minister Jun Azumi said Tuesday.

"If there is any scheme that could help ease tensions worldwide, including financial markets, over the rescue of Greece, I will not reject the possibility that Japan will share some burdens after being briefed" by European officials on the possible scheme, Azumi told reporters.

But Azumi stressed that discussions on such measures with his U.S. counterpart Timothy Geithner will only take place provided that European nations map out their own outline to resolve the issue.
