The 2027 National Defense Authorization Act authorizes up to $1.5 billion to reorganize war‑reserve stockpiles and develop a crisis‑management strategy that places Taiwan and the Philippines in a joint defense framework called the "First Island Chain Security Cooperation Initiative." The legislation also obliges the United States, under the 1951 Mutual Defense Treaty, to assist Manila if any civilian, sailor or Filipino soldier is killed as a result of Chinese actions.
Both partners sit on the front line of China’s efforts to assert territorial claims in the western Pacific. The Philippines views most of its western exclusive economic zone as internal waters, while China treats Taiwan as a renegade province that must be "reunified." U.S. moves to boost the military capabilities of Taiwan and the Philippines have accelerated following recent clashes in the South China Sea and growing concerns over a possible invasion of Taiwan.
