Indonesia and Japan signed a defense cooperation agreement on Monday, according to statements from Indonesian officials. The signing occurred during a visit by Japanese Defense Minister Shinjiro Koizumi to Jakarta, where he met with Indonesian Defense Minister Sjafrie Sjamsoeddin.

This development comes after Japan relaxed its long-standing arms export rules last month, permitting the sale of lethal weapons to nations with which it has defense pacts. The agreement emphasizes collaboration in humanitarian assistance and disaster relief, joint military exercises, and maritime cooperation, as outlined by a spokesperson.

Indonesian Defense Ministry spokesperson Rico Ricardo Sirait stated that the pact represents efforts to strengthen defense relations between the two countries. Officials highlighted the importance of maintaining regional peace and stability amid ongoing global challenges.

Japan had maintained strict limits on arms exports for decades, primarily restricting sales to non-lethal equipment. The recent policy change allows Japanese firms to export lethal weapons under specific conditions, tied to existing defense agreements.

This shift enables closer military ties with partners like Indonesia, which shares strategic interests in the Asia-Pacific region. The agreement builds on prior interactions between the two nations, including discussions on security cooperation. While details of potential arms sales were not specified, the pact sets a framework for future joint activities.

Both countries face common concerns such as maritime security in contested areas.

The defense ministers signed the agreement at the Defense Ministry office in Jakarta. Photographs from the event showed the officials during the meeting. No immediate announcements were made regarding specific implementations or timelines for the cooperative initiatives outlined in the pact.
