MANILA, Philippines — The presence of Chinese naval vessels near two strategically important maritime approaches of the Philippines is drawing renewed attention after five People’s Liberation Army Navy (PLAN) vessels were reportedly monitored off Eastern Samar and northern Luzon in recent days.
The sightings, first reported by The Manila Times, involved four Chinese warships observed off Hilabaan, Eastern Samar, on August 31, followed the next day by another PLAN vessel monitored near Ilocos Norte. National security expert Jose Antonio Goitia said the movements should be closely watched, while stressing that they should not automatically be interpreted as preparations for confrontation.
Four warships reported off Eastern Samar
According to information provided by Goitia, the four vessels seen off Eastern Samar were identified as the Luyang III-class destroyer Xigase (BN 159), Xuanwei (BN 535), Luyang III Mod-class destroyer Baotou (BN 133), and Jiangkai II-class frigate Yixing (BN 537).
A fifth Chinese naval vessel was subsequently monitored on September 1 at approximately 75.40 nautical miles from Bobon, Burgos, Ilocos Norte, according to the same account.
Goitia described the warships as vessels with capabilities that include air defense, long-range strike and anti-submarine warfare.
The locations are significant because Eastern Samar faces the Philippine Sea, while northern Luzon sits near the approaches to the Luzon Strait, a strategically important passage connecting the South China Sea and Philippine Sea.
Still, the available reports do not establish that the Chinese ships were conducting hostile operations against the Philippines.
The sightings come amid wider Chinese maritime activity
The reported movements come as the Armed Forces of the Philippines continues to document substantial Chinese maritime activity in the country’s western waters.
For August, the AFP said it monitored 56 Chinese vessels around four major West Philippine Sea features: Ayungin Shoal, Bajo de Masinloc, Escoda Shoal and Pag-asa Island.
The figure consisted of 15 PLAN warships and 41 China Coast Guard vessels, compared with 48 Chinese vessels monitored in July.
The AFP’s August breakdown showed:
- Ayungin Shoal: 18 Chinese vessels
- Bajo de Masinloc: 23 vessels
- Escoda Shoal: 9 vessels
- Pag-asa Island: 6 vessels
AFP spokesman for the West Philippine Sea Rear Adm. Roy Vincent Trinidad cautioned that longer-term data would be needed before drawing conclusions about broader patterns in Chinese deployments.
The Philippine Navy also monitored 18,534 vessels nationwide during August, including 15,989 foreign vessels and 2,545 domestic vessels. Philippine forces issued radio challenges to 12,502 vessels, while 6,032 did not respond, according to AFP figures.
Another Chinese vessel raises separate concerns
The warship sightings are also occurring against the backdrop of another Chinese maritime operation that has attracted scrutiny.
The Philippine Coast Guard recently reported that the Chinese survey vessel Haiyang Dizhi Shihao, a 76-meter vessel operated by China’s Guangzhou Marine Geological Survey, spent 25 days inside the Philippine exclusive economic zone, including approximately three weeks within the 12-nautical-mile territorial sea of Bajo de Masinloc, or Scarborough Shoal.
PCG spokesman Rear Adm. Jay Tarriela said the Department of Foreign Affairs had confirmed that the vessel did not have a Philippine permit to conduct marine scientific research. The PCG also said the vessel is capable of deep-sea drilling and was tracked using satellite-based monitoring after intermittently turning off its automatic identification system.
That development is separate from the reported PLAN warship sightings off Eastern Samar and Ilocos Norte and should not be treated as evidence that the two activities were coordinated.
Why the locations matter
The strategic importance of the latest sightings goes beyond the individual ships themselves.
Eastern Samar opens toward the Philippine Sea, while the northern Philippines is close to the Luzon Strait and the waters leading toward Taiwan and the wider Western Pacific.
For maritime-security observers, the appearance of sophisticated naval vessels near these approaches is therefore significant enough to warrant continued monitoring.
But experts also caution against immediately interpreting every foreign naval movement as an indication of an impending military confrontation.
Goitia himself said vigilance should not be confused with confrontation, emphasizing the importance of identifying vessels, tracking their movements and documenting unusual activity.
What happens next?
For the Philippines, the more important question may not simply be where the Chinese vessels were seen, but whether similar deployments continue and whether authorities identify a consistent operational pattern.
The AFP has already indicated that short-term observations can be insufficient for determining strategic trends. More sustained monitoring could therefore provide a clearer picture of whether the latest sightings represent routine naval movements, exercises, transit activity or something more deliberate.
For now, there is no publicly established evidence that the five reported Chinese naval vessels were preparing for an attack or confrontation with the Philippines.
What is clear is that Chinese naval and maritime activity around Philippine waters remains substantial—and the latest sightings have added two more strategically important areas to the conversation.
The question now is not simply whether Chinese warships were there.
It is what their presence means—and whether they will return.
