The Diet on Friday approved a revised Japan-U.S. agreement that gives the Self-Defense Forces more leeway in providing ammunition and other supplies to the U.S. military.

The agreement, aimed at boosting logistic cooperation between Japanese and U.S. forces, is in line with changes brought about by the divisive security laws enacted early last year. The laws side-stepped constraints imposed by pacifist Article 9 of the Constitution, which prohibits Japan from waging war, and authorized the use of collective self-defense.

The move to amend the bilateral Acquisition and Cross-Servicing Agreement comes as Prime Minister Shinzo Abe's government seeks to bolster Japan's security alliances, reviewing new legislation to counter North Korea's continued provocations and other security threats. But public concerns have surfaced that the changes undermined Japan's postwar pacifist policy stance.
