While the Diet took a short recess during late April’s Golden Week, Prime Minister Sanae Takaichi and other ministers visited countries in Southeast Asia and Africa. They sought deals with those countries over resources, including rare earth minerals, that are critical to Japan from both economic and national security perspectives. Diplomacy under the Takaichi administration relies heavily on Shinzo Abe’s legacy of using economic incentives to leverage security policy.
Takaichi met with Australian Prime Minister Anthony Albanese in Canberra on May 4, and they signed a Joint Declaration on Economic Security Cooperation. Japan depends on Australia for 40 percent of its LNG imports and 65 percent of its coal imports. The declaration affirms that both countries will deepen their partnership on energy security and supply chain resilience. The two leaders also signed a joint statement on critical minerals, which will support projects by Japan’s private sector to develop gallium, magnesium, fluorite, and nickel in Australia.
The joint declaration rejects “all forms of economic coercion,” including export restrictions on critical minerals, a statement presumably directed at China. The declaration explains that export restrictions significantly interfere with global supply chains. Last January, China imposed strict controls on exports of dual-use products to Japan. Observers widely interpreted the controls as a sanction for Takaichi’s comment on the Taiwan contingency in November 2025 and her later refusal to apologize for it. It was not out of the ordinary then for Takaichi to strike an alternative deal with Australia to secure minerals and other raw materials.
Takaichi and Albanese also signed a Leaders Statement on Enhanced Defense and Security Cooperation, which called bilateral relations between their countries a “special strategic partnership.” They agreed to maintain assets, including upgraded Mogami frigates, and to cooperate on supply chain issues. Takaichi called Australia a “quasi-ally” in her meeting with Albanese.
Takaichi’s visit to Vietnam, which occurred before her meetings in Australia, showed a similar tendency to emphasize economic incentives. In her meeting with Vietnamese President To Lam on May 2, Takaichi urged cooperation by the two countries to strengthen the supply chain, including the export of rare earth minerals mined in Vietnam. In her policy speech in Hanoi, she emphasized that Free and Open Indo-Pacific (FOIP) is the lynchpin of Japanese foreign policy. FOIP is a diplomatic concept originated in 2016 by former prime minister Shinzo Abe. It is regarded as one of his major foreign policy achievements.
Takaichi’s cabinet ministers took the same tack on their trips abroad. Minister of Defense Shinjiro Koizumi visited Indonesia and the Philippines to reinforce their security ties with Japan. In Indonesia, he signed of a Defense Cooperation Arrangement expanding security ties in people-to-people exchanges, education and joint training, as well as defense equipment and technology cooperation.
At his meeting with Philippine Defense Minister Gilberto Teodoro in Manila, the two officials issued a Joint Press Statement (Japanese text) under which Japan would transfer retired Abukuma-class destroyer escorts to the Philippines.
Located on the first island chain, the Philippines has been suffering from Chinese maritime advances around its territory, including the Spratly Islands. Japan is now trying to support Manila’s counter-efforts. Takaichi administration has removed well-established restrictions on Japan’s exports of defense equipment in April, which had previously been limited to five categories – rescue, transport, warning, surveillance, and minesweeping. The export of Abukuma-class destroyers is expected to mark the first example of Japan’s new policy on defense sales.
In his visit to Zambia, Angola, Kenya and South Africa from April 30 to May 5, Foreign Minister Toshimitsu Motegi underscored the importance of securing the supply chain for critical minerals and of implementing FOIP. In his policy speech in Nairobi, Motegi said that the core principles of FOIP –freedom, openness, diversity, inclusiveness, and the rule of law – would remain unchanged.
The Takaichi administration’s Golden Week diplomacy made clear its emphasis on economic leverage in foreign policy. Takaichi sought the support of Australia, as a quasi-ally, through economic security cooperation. Koizumi used the export of destroyers to the Philippines to enhance security capabilities against China. Motegi explored opportunities for critical minerals in Africa under the name of FOIP.
Diplomatic breakthroughs in the form of economic incentives that were good for Japanese businesses were a hallmark of the former Abe administration. He and his advisers believed that the promise of a robust economy would trump issues of pride and history. His negotiations with Russia in the decades-long dispute over the Northern Islands of Japan exemplified this strategy.
In 2016, Abe proposed eight points (English) of economic cooperation with Russia, including joint development of natural resources in Sakhalin and financial support for Russian businesses, as leverage to take back the Northern Territories. However, two years later, Abe compromised with Russian President Vladimir Putin to reduce Japan’s demand from four islands to just two.
Abe’s commercial approach was a total failure. Putin held to his absolutist interpretation of the 1951 San Francisco Peace Treaty. Russia’s administration of all four islands meant ownership and that they would not be returned. Negotiations have not continued as they were interrupted by Russia’s 2022 invasion of Ukraine. Abe’s inability to reach a deal with Putin completely undercut his idea that economic cooperation will reinforce Japan’s security. The Abe administration failed to account for Russian sentiment that territory obtained in the World War II at great sacrifice could not be the subject of a mere economic transaction.
Takaichi’s diplomacy has the same structure and rationale as Abe’s. She believes that an offer of economic support from Japan is so attractive that Japan can gain national security advantages. A factor feeding into this view may be that the offices of the Abe Administration were and of the Takaichi Administration are dominated by personnel seconded from the Ministry of Economy, Trade, and Industry (METI). By replicating Abe’s unsuccessful strategy, Takaichi is now facing pressure from China and, unavoidably, greater involvement in the current turbulent, war-based international order.
Takaichi, however, is not leaving Japan’s security to mercantilism alone. She is expanding the country’s hard power. During Golden Week, the Japanese Self-Defense Forces for the first time participated in an annual joint military exercise with the United States and the Philippines, Balikatan 26. In response, a spokesperson for the Chinese Ministry of National Defense commented “We urge the relevant countries to stop forming blocs and stoking camp confrontation and do more that truly contributes to regional peace and stability.” Neither Japan’s soft nor hard power expansion is bound to impress a restless China.
