Tokyo 与 Canberra 签署升级安全声明，表示两国联盟现在体现「前所未有的战略对齐」与更高的「战略深度」，并将合作承诺从政策对话扩展到实际运作，包括驱逐舰、无人系统、网路、太空及国防装备联合生产。关键象征是 Australia 最近在一项 multi-billion-dollar 采购中选择日本军舰，Japan 希望这将成为向 New Zealand 或 India 等国家输出下游产品的枢纽。Japan 的军事姿态已明显走向更深度的作战整合：两军进行频繁联合演习，双方政府都形容协同程度远高于以往，防卫大臣 Shinjiro Koizumi 表示区域不确定性现今「日益严峻」。
经济安全是此次访问第二支柱，Japan 目前是 Australia 第二大外国投资者，Australia 被列为 energy、iron ore、food 等基本大宗商品与其他原物料的核心供应国。双方也加深关键矿产合作：除镍与稀土外，列入优先的专案共有 6 项；Japan 与 Australia 的公私部门已持续十余年投资 Lynas Rare Earths Ltd 及相关加工能力，并于上年向 Japan 工业界供应重稀土产品。经历中国对稀土出口施压带来的多次生产冲击后，两国正式同意抵抗非市场化的贸易胁迫，含出口限制与有害过剩产能等政策，以提升对经济胁迫、尤其是供应链武器化的韧性。
Japan’s Prime Minister Sanae Takaichi arrived in Canberra on Sunday for a three-day visit focused on defense coordination, critical minerals, cyber cooperation, and broader economic security. Her trip built on an updated Indo-Pacific vision announced in Hanoi, an update of the framework first articulated by Shinzo Abe about ten years ago. In initial statements there and at home, she and Prime Minister Anthony Albanese made energy, investment, and stable supply chains joint priorities while also discussing security issues involving China. The timing reflects Japan’s broader strategic shift: Tokyo is trying to reduce dependence on single suppliers and strengthen practical partnerships in the Indo-Pacific as U.S. attention is perceived as more dispersed and China as more assertive.
Tokyo and Canberra signed an enhanced security statement saying their alliance now reflects unprecedented strategic alignment and greater strategic depth, with commitments extending beyond policy dialogue into practical cooperation on frigates, unmanned systems, cyber, space, and joint production of defense equipment. A key symbol is Australia’s recent decision to buy Japanese naval vessels under a multi-billion-dollar deal, which Japan hopes will become a hub for downstream exports to New Zealand or India. Japan’s military posture has moved strongly toward operational integration: the two armed forces conduct frequent joint exercises, both governments describe coordination as far deeper than before, and Defense Minister Shinjiro Koizumi said regional uncertainty is now increasingly severe.
Economic security is the second pillar of the visit, with Japan now the second-largest foreign investor in Australia and Australia highlighted as a core supplier of energy, iron ore, food, and other commodities. The two sides deepened critical-mineral cooperation by prioritizing six projects, including nickel and rare earths. Japanese and Australian public-private entities have invested for over a decade in Lynas Rare Earths Ltd and related processing, including supplying heavy rare earth output to Japan’s industry last year. After repeated production shocks from Chinese export restrictions, both governments formally agreed to resist non-market coercive trade practices, including export limits and harmful overcapacity, to build resilience against economic coercion and the weaponization of supply dependencies.
