## Prediction

Over the next month, China will likely exploit U.S. focus on Iran to push more assertive maritime actions in the South China Sea and East China Sea, normalizing a background hum of gray-zone coercion alongside U.S.–Iran hostilities in the Gulf. Incidents similar to the recent Chinese–Philippine clash at Second Thomas Shoal will recur, and Beijing will increase legal and rhetorical pressure on Japanese and Philippine militarization. This parallel friction will stretch U.S. naval presence and alliance management across INDOPACOM and CENTCOM, complicating crisis response in both theaters. Confirmation would be additional ramming, water cannon, or unsafe intercept episodes backed by aggressive Chinese legal narratives; disconfirmation would be a noticeable Chinese maritime de-escalation during the Gulf crisis.

## Drivers

- Recent Chinese–Philippine boat clash at Second Thomas Shoal
- Emerging trend of normalized gray-zone maritime coercion in East Asia and Gulf chokepoints
- Chinese warnings about Japanese militarization amid broader U.S. commitments
- U.S. naval and air assets heavily engaged in Gulf theater
