Japan will join international sanctions against Libya if necessary, Finance Minister Yoshihiko Noda said Friday.

The comment came after the U.N. Security Council unanimously voted Feb. 26 to back a sanctions resolution aimed at ending the Libyan government's attacks on its citizens.

"We would like to respond if we judge that international collaboration is necessary," Noda told a news conference.

Under the U.N. resolution, Tokyo would freeze the assets of six Libyans, including the African country's leader, Moammar Gadhafi, if they possess any assets in Japan, a Finance Ministry official said.
