- Xiang Yang Hong 33 deployed a service boat toward the reef, confirming ongoing unauthorized research operations.

Why it matters: The Philippines asserts its sovereign rights and seeks to deter further Chinese incursions, while China frames the activity as lawful, highlighting a clash over maritime jurisdiction that could affect resource exploitation and regional stability. The dispute also involves Chinese maritime militia vessels, which Manila views as a militarized challenge to its exclusive economic zone.
