What We Know

China's Southern Command of the People's Liberation Army (PLA)—the armed forces of the People's Republic of China—announced on August 1, 2026, that it had conducted a joint air-sea exercise around Scarborough Reef in the South China Sea, according to the Handelsblatt. The reef is also known in Chinese as Huangyan Dao.

Beijing characterized the maneuver as a "necessary response" to actions by "certain countries" that undermine regional peace and stability. No specific country was named.

The stated objective of the exercise was to test and improve the combat capability of Chinese forces in order to defend "national territorial sovereignty and maritime rights."

Context

Scarborough Reef is claimed by both China, which calls it Huangyan Dao, and the Philippines. It represents one of the most frequent points of friction between the two nations, particularly over fishing rights.

A vessel identified by the Philippine Navy as a Chinese naval ship was already spotted at Scarborough Reef in mid-June 2026.

Beyond the Philippines, Indonesia, Brunei, Malaysia, and Vietnam also claim portions of the South China Sea.

In 2016, the Permanent Court of Arbitration (PCA)—an international arbitral organization and tribunal founded in 1899 with its seat at the Peace Palace in The Hague—ruled that Beijing's extensive claims in the South China Sea are not covered under international law. China refuses to acknowledge this ruling.

What Remains Uncertain

Beijing has not specified which countries are targeted by its warning. No official response from the Philippine Embassy in Beijing was available at the time of publication.
