China steps up maritime push against Philippines, Japan, with eye on Taiwan

China's coordinated maritime pressure on Australia's key Indo-Pacific partners (Philippines, Japan) and explicit linkage to Taiwan reunification directly threatens the alliance architecture upon which Australia's regional security depends. This signals PLA operational readiness and political resolve at the northern arc and raises the probability of a kinetic Taiwan scenario, which would test AUKUS commitment and force Australia into crisis decision-making on Pillar 7 (Alliance) and Pillar 6 (Maritime Defence).
