Seiji Maehara, chief of the opposition Democratic Party of Japan, said Saturday he will not run in the party's presidential election in September if he fails to unify views within the party on foreign affairs, security and other basic policies.

Maehara earlier indicated his plan to consolidate views by June along the lines of his ideas on defense issues and his belief that China poses a threat.

Speaking on a Nippon TV program, Maehara said he "has not yet considered" whether to seek re-election but added such action "hinges on whether I can consolidate visions (within the party) on foreign affairs, security and domestic politics, as I have pledged to do."
