Mischief Reef
In 1994, China had a similar confrontation by asserting its ownership of Mischief Reef, which was inside the claimed EEZ of the Philippines. However, the Philippines only made a political protest, since according to the Henry L. Stimson Center, the Philippine Navy decided to avoid direct confrontation. This was partly based on the Johnson South Reef Skirmish, in which the Chinese had killed Vietnamese troops even though the conflict took place near the Vietnamese-controlled area.
