Indonesia and Australia are exploring a trilateral security cooperation framework with Japan, marking a significant evolution in Jakarta's traditionally non-aligned foreign policy stance as regional tensions intensify in the Indo-Pacific.
Defense Minister Sjafrie Sjamsoeddin confirmed the initiative following a bilateral defense ministers' meeting on March 12, telling reporters that he would "speak with Japan's defense minister" to advance coordination. The proposed framework would center on Morotai Island in North Maluku province, positioning the strategic location as a joint training hub for the three democracies.
From Non-Alignment to Practical Partnerships
The move represents a departure from Indonesia's long-standing commitment to strict non-alignment in great power competition. While Jakarta has traditionally positioned itself as a neutral broker in regional affairs, practical security concerns are driving closer cooperation with established democracies facing similar challenges from an assertive China.
The initiative builds on the bilateral security treaty signed by Indonesia and Australia in February 2026, which includes provisions for consultation on joint responses to situations affecting their shared security interests. According to Japan's Asahi Shimbun, expanding this framework to include Tokyo would create a powerful trilateral alignment among three of the region's most capable democracies.
The February treaty itself represented a historic milestone in Indonesia-Australia relations, codifying security cooperation that had previously remained informal and ad hoc. The agreement includes mutual consultation clauses that stop short of collective defense commitments but establish mechanisms for coordinated responses to regional security challenges.
