China Patrols Huangyan Island Amid Rising Tensions
The People’s Liberation Army (PLA) Southern Theater Command conducted combat readiness patrols in the territorial waters, airspace, and surrounding areas of Huangyan Island (Scarborough Shoal) on September 2, deploying naval and air forces in what the command described as a response to “rights-violation and provocative acts.” The operation marks the latest escalation in a sustained military campaign that has intensified since August, as tensions between China and the Philippines over the disputed South China Sea feature continue to mount.
According to the Southern Theater Command’s official statement, the patrols are aimed at “further enhancing control of relevant sea areas and airspace” and serve as “an effective countermeasure to cope with all sorts of rights-violation and provocative acts.” The command reaffirmed that Huangyan Dao is China’s inherent territory and stated that forces will “resolutely safeguard China’s sovereignty and security and firmly uphold peace and stability in the South China Sea.”
Sustained Military Operations Since August
The September 2 patrol is part of a broader campaign of intensified military activity around Huangyan Island that began in August. The Southern Theater Command stated that since August, its forces have “strengthened readiness patrols in the territorial sea and airspace of Huangyan Dao and its surrounding areas.” This sustained presence has included multiple deployments of naval vessels and aircraft, including Type 052D destroyers, Type 054A frigates, H-6K bombers, and J-16 fighters.
Video footage released alongside the patrol announcement, as reported by Lianhe Zaobao, showed at least two military aircraft with call signs “Jianfeng 01” and “Lieying” flying near Huangyan Island. The footage also captured Chinese naval forces broadcasting warnings to a Philippine aircraft in both Chinese and English, telling it to “leave immediately” to avoid “misunderstanding and misjudgment.” Pilots in the video spoke of visiting the “ancestral sea” and jointly protecting the “maritime frontier.”
The patrols follow a series of escalating incidents in the region. On August 21, three Philippine aircraft—an Islander, C-208, and PA-31T—allegedly intruded into Huangyan Island’s airspace without Chinese government approval. China Daily reported that Senior Colonel Li Jianjian, spokesman for the PLA Southern Theater Command’s Air Force, said the command deployed naval and air forces to track, monitor, and issue verbal warnings to the aircraft. Li warned that the Philippine actions “seriously violate China’s sovereignty and could easily lead to misunderstandings and miscalculations.”
Just days before the September 2 patrol, the China Coast Guard conducted law enforcement patrols in the territorial waters of Huangyan Island and surrounding areas on August 30. China Daily reported that the CCG has strengthened its patrols in these waters since August, addressing vessels engaged in “illegal activities” in accordance with laws and regulations. The patrols were described as further enhancing the management and control of the waters while safeguarding China’s territorial sovereignty and maritime rights.
On September 1, the day before the latest patrol, the PLA Navy held a live-fire maritime exercise in the South China Sea involving multiple destroyers, including the Type 052D destroyers Weinan, Changsha, and Guilin, as well as the Type 055 destroyer Zunyi. According to Global Times, the exercise included shore bombardment drills in which the Zunyi successfully struck all targets within the designated time.
A Long-Simmering Dispute
Huangyan Island, known as Scarborough Shoal in English and Bajo de Masinloc in the Philippines, is a triangular coral reef formation located approximately 124 nautical miles off the Philippine coast. The feature has been a major flashpoint in the South China Sea dispute since a 2012 standoff between Philippine and Chinese vessels.
China claims sovereignty over the feature as part of the Zhongsha Islands, while the Philippines claims it as part of its exclusive economic zone under the United Nations Convention on the Law of the Sea (UNCLOS). In 2016, an international arbitral tribunal ruled that China’s sweeping claims in the South China Sea had no legal basis under international law and declared Scarborough Shoal a common fishing ground. China refuses to recognize the ruling.
Tensions have escalated significantly throughout 2026, with the Philippines conducting multiple joint maritime activities with the US, Japan, and Australia near Huangyan Island. The Philippines has also taken legal and diplomatic steps, including depositing an updated nautical chart covering Bajo de Masinloc with the United Nations in August and enacting the Maritime Zones Act and Archipelagic Sea Lanes Act, which China has condemned as an attempt to legitimize the 2016 arbitration ruling through domestic legislation. As SCMP reported, Beijing has accused Manila of “seriously infringing China’s territorial sovereignty and maritime rights in the South China Sea.”
The Philippines has firmly rejected China’s position. The Department of National Defense stated that Bajo de Masinloc is an “integral and longstanding part” of Philippine national territory and that the country’s maritime zones are established in accordance with UNCLOS and the 2016 Arbitral Award. As reported by Cebu Daily News, the DND declared: “We will not be deterred by China’s false narratives and hooliganism.” The department also emphasized that Chinese military activities do not alter the legal status of maritime features or the Philippines’ maritime entitlements under international law.
Analysis: A Deliberate Show of Force
The sustained pattern of patrols, live-fire exercises, and coast guard operations around Huangyan Island reflects a deliberate Chinese strategy to assert control over the disputed feature through a combination of military presence and administrative measures. Chinese military affairs expert Zhang Junshe, quoted by Global Times, characterized Philippine actions near Huangyan Dao as increasingly appearing to be “political posturing,” noting that China’s normalized control over the area makes Philippine joint patrols more performative than substantive.
The timing of the September 2 patrol is significant, coming just days after Philippine aircraft allegedly intruded into the area and following a series of Philippine diplomatic moves, including the UN chart submission. The patrols also follow China’s designation of Huangyan Island as a national nature reserve and the issuance of management measures for the reserve in August, which the Philippines has strongly protested as illegitimate.
Regional analysts have noted that the situation, while tense, remains within manageable bounds. Hu Bo, director of the South China Sea Strategic Situation Probing Initiative in Beijing, said the situation should still be within control. However, the escalating frequency and scale of military operations around the feature raise concerns about the potential for miscalculation, particularly given the involvement of multiple external actors in the region.
What to Watch For
The immediate trajectory of tensions around Huangyan Island will depend on several factors: whether the Philippines continues its joint patrols with external partners, how China responds to the Philippine UN submission and maritime legislation, and whether the two sides can find diplomatic channels to de-escalate. The US-Philippine mutual defense treaty obligation adds another layer of complexity, with Washington having warned that it is obligated to defend the Philippines if Filipino forces come under attack in the South China Sea.
For now, the PLA Southern Theater Command has made clear its intent to maintain a persistent military presence around Huangyan Island. As the command’s statement emphasized, its forces “will resolutely safeguard China’s sovereignty and security and firmly uphold peace and stability in the South China Sea.” The question remains whether this sustained pressure will deter Philippine actions or further entrench the standoff over one of the most strategically significant features in the contested waters.
