Taku Yamasaki, secretary general of the Liberal Democratic Party, said here Thursday that the party would work toward lifting a freeze on Japanese participation in United Nations peacekeeping efforts.

The LDP will also review Tokyo's five conditions for joining U.N. peacekeeping operations so Japan can more effectively contribute to the international community, Yamasaki told reporters.

He added that the ruling LDP will seek to revise a law on Japan's cooperation in U.N. peacekeeping operations at an extraordinary Diet session convening in the fall.

A 1992 law restricts Self-Defense Forces' involvement in peacekeeping forces and sets strict conditions on sending personnel abroad to participate in peacekeeping missions. The law stipulates the SDF can only be dispatched to U.N. peacekeeping operations if a ceasefire is in place.
