Japan's PM Takaichi Makes Diplomatic Debut at ASEAN Summits in Malaysia, Champions Free and Open Indo-Pacific

Prime Minister Takaichi Embarks on First Diplomatic Mission

Japanese Prime Minister Sanae Takaichi departed for Kuala Lumpur, Malaysia, on Saturday, October 25, 2025, to participate in the 47th ASEAN Summit and Related Summits. This marks her inaugural diplomatic engagement since assuming office on October 21, 2025, making her Japan's first female prime minister. The summits, hosted by Malaysia under the theme 'Inclusivity and Sustainability,' are scheduled to run from October 26 to 28, 2025, at the Kuala Lumpur Convention Centre (KLCC).

Advancing the Free and Open Indo-Pacific Initiative

During the high-level meetings, Prime Minister Takaichi is set to emphasize the critical importance of Japan's 'Free and Open Indo-Pacific' (FOIP) initiative. This policy, a cornerstone of Japan's diplomatic strategy, aims to foster a region characterized by openness, transparency, inclusiveness, and adherence to the rule of law. Japan has consistently supported the ASEAN Outlook on the Indo-Pacific (AOIP), recognizing shared fundamental principles between the two frameworks. A joint statement is expected to be adopted during the ASEAN-Japan Summit to further promote synergies and cooperation between FOIP and AOIP for regional peace, stability, and prosperity.

Strengthening Regional Cooperation and Security

Prime Minister Takaichi has also pledged to enhance cooperation with the Association of Southeast Asian Nations (ASEAN) across several key areas. These include bolstering collaboration in security, cybersecurity, and artificial intelligence. She underscored the necessity of an international order based on the rule of law, a stance that implicitly addresses concerns over coercive actions in regional waters. Japan plans to expand support for ASEAN nations through its official security assistance program, which encompasses the provision of defense equipment and other essential items to like-minded partners. Additionally, cooperation in disaster response and maritime security is slated for enhancement.

Key Discussions and Regional Developments

The 47th ASEAN Summit brings together leaders from the ten ASEAN member states, along with dialogue partners such as the United States, China, Japan, South Korea, Australia, and New Zealand. Notable attendees include US President Donald Trump and Chinese Premier Li Qiang. A significant development during these summits is the formal admission of Timor-Leste as the 11th ASEAN Member State. Discussions are expected to cover a wide range of issues, including regional security, economic resilience, and inclusive growth, reflecting Malaysia's chairmanship priorities for 2025.
