U.S. Defense Secretary William Cohen and Defense Agency Director General Hosei Norota agreed Wednesday to share information if North Korea test-fires a ballistic missile.

During their meeting at a Tokyo hotel, Norota asked Cohen to share U.S. intelligence with Japan even if a missile fell far from Japanese territorial waters and Self-Defense Forces failed to fully track it, Defense Agency councilor Yoshiki Mine said in a briefing to reporters.

The two nation's defense chiefs also agreed that Japan, the U.S. and South Korea will exchange an "extended level" of information regarding North Korea's next missile launch. The spokesman declined to further elaborate.
