The Philippine Coast Guard said Chinese forces fired flares towards one of its unarmed aircraft during a surveillance flight over the Spratly Islands. [The South China Morning Post reported that the coast guard released video showing the Chinese military appearing to fire flares near the aircraft as it flew close to Subi and Mischief Reefs](https://www.scmp.com/news/china/military/article/3367146/south-china-sea-manila-says-flares-fired-aircraft-near-subi-mischief-reefs?utm_source=rss_feed), features the Philippines calls Zamora and Panganiban.

[BusinessWorld reported the flight took place on September 7 and that Chinese forces at Subi challenged the aircraft by radio before firing flares, with forces at Mischief repeating the action](https://bworldonline.com/the-nation/2026/09/10/776025/china-forces-fire-multiple-flares-at-unarmed-pcg-aircraft-over-spratlys/). The crew said the discharge of flares at an aircraft in flight endangers flight safety. [Philstar reported the crew also observed a substantial number of Chinese maritime militia vessels sheltering inside the lagoons of both reefs](https://www.philstar.com/headlines/2026/09/11/2555534/china-fires-flares-pcg-aircraft). The Philippine crew told the Chinese side by radio that its presence on the reclaimed features violates international law and that the flight was routine.

The disclosure is part of a broader Philippine practice of publishing evidence rather than handling incidents quietly. [The South China Morning Post noted separately this week that Manila made public a Chinese diplomatic note on the South China Sea](https://www.scmp.com/news/china/article/3367130/manila-exposes-south-china-sea-note-chinese-coal-mine-farming-plan-scmps-7-highlights?utm_source=rss_feed). Beijing claims sovereignty over the Spratly Islands and has consistently described Philippine operations there as intrusions into Chinese territory. The South China Morning Post account of the September 7 flight carried Manila's version and video without a Chinese response.

## What this means

Each publicised incident raises the probability that an accident, not a decision, triggers the mutual defence treaty between Manila and Washington, and that treaty is the mechanism by which a reef dispute becomes a shipping and insurance problem for the busiest trade route in Asia. Shipowners, cable operators and offshore energy developers in the area price that tail risk today through insurance and route planning. Manila's strategy of releasing video builds an evidentiary record for international forums, and it also removes the option of quiet de-escalation that both governments used to rely on.

## What to watch

- Whether Beijing responds publicly with its own account of the September 7 flight, which would show whether it now contests the Philippine evidence directly or ignores it.
- Whether the United States flies or sails alongside Philippine assets in the same area, the step that converts a bilateral incident into an alliance commitment.
- The number of Chinese militia vessels stationed in the Spratly lagoons over coming weeks, a measure of whether Beijing is reinforcing or holding position.
