Japan's 10-year plan for military support to Vietnam, the Philippines, Malaysia, and Indonesia to deter China is aligned with American interests in the region

The appointment of Kurt Campbell, President Biden's Indo-Pacific foreign policy strategist, as Deputy Secretary of State in February 2024 again emphasized the importance of the Southeast Asian region for the American security network.

According to Kurt Campbell's doctrine, in particular, Washington should comprehensively expand ties with the Philippines, Vietnam, Thailand, Malaysia, and Indonesia (the leading manufacturing economies in the region) to implement campaigns to reduce dependence on China and to guarantee ASEAN's further integration into the alliance of democracies.

In 2023, the Biden administration made significant progress in developing economic and security relations with Hanoi and Manila and found common ground with Bangkok, which continues to restore democracy after ten years of military rule by Prayut Chan-ocha.
