Quad Endorsement

In July 2026, the foreign ministers of Japan, the United States, Australia, and India met on the sidelines of the ASEAN Foreign Ministers' Meeting in Manila. They issued the 'Joint Press Release on Quad Cooperation with ASEAN,' reaffirming support for ASEAN centrality and unity and the 'ASEAN Outlook on the Indo-Pacific (AOIP).' The Quad foreign ministers also reaffirmed their commitment to a 'Free and Open Indo-Pacific (FOIP)' and outlined their intention to deepen cooperation with ASEAN, with FOIP as a core pillar.

FOIP Origins and Evolution

Former Prime Minister Shinzo Abe proposed the FOIP at the Sixth Tokyo International Conference on African Development (TICAD VI) in Nairobi, Kenya, in August 2016. Abe viewed Asia and Africa, and the Pacific and Indian Oceans, as an inseparable and integrated region, and expressed Japan's determination to maintain 'freedom from coercion,' the 'rule of law,' and a 'market economy' across it. The FOIP philosophy won broad acceptance across the Indo-Pacific, from advanced Western nations such as the United States and Australia to developing countries including African nations, India, and ASEAN member states. In June 2019, ASEAN adopted the AOIP as its own Indo-Pacific vision, guided by principles including ASEAN centrality, inclusiveness, and respect for international law.

Japanese Prime Minister Sanae Takaichi attended the Japan-ASEAN Summit in Kuala Lumpur, Malaysia, in October 2025. At the meeting, she stated Japan's commitment to safeguarding the peace, stability, and prosperity of the Indo-Pacific together with ASEAN, by evolving FOIP and deepening synergy with the AOIP. Following the summit, the leaders of Japan and ASEAN issued the 'Joint Statement on the Further Promotion and Implementation of the AOIP.' The statement affirmed that implementing the AOIP contributes to a rules-based international order and a free and open Indo-Pacific, and welcomed Japan's efforts to promote cooperation rather than division and confrontation through the FOIP. When Takaichi visited Hanoi, Vietnam, in May 2026, she delivered a speech at Vietnam National University outlining the 'Updated FOIP,' asserting that the case for FOIP remains as strong as ever.
