Hiroshima Mayor Kazumi Matsui said he plans to urge world leaders to foster mutual trust through dialogue in his statement marking the 70th anniversary of the U.S. atomic bombing of his city.

"My Peace Declaration (to be issued Aug. 6) will call on leaders around the world, including Japan, to stop taking actions that could cause mistrust in each other," so no one ever again suffers a nuclear attack, Matsui said Thursday in Tokyo at the Foreign Correspondents' Club of Japan.

Matsui said he will not directly mention in the declaration the Abe government's controversial security bills that would ease restrictions on use of the Self-Defense Forces, but he pointed to the need to uphold a broad diplomatic policy that focuses on dialogue rather than making preparations for possible threats.
