Over the last two years, tensions between China and the Philippines at Second Thomas Shoal have emerged as the focal point of frictions in the South China Sea. The Philippines maintains a detachment of marines at Second Thomas Shoal stationed aboard the BRP Sierra Madre, a Philippine navy ship intentionally grounded there in 1999. Ever […]
Recently there have been many dangerous encounters between the Philippines and China in the waters around the Second Thomas Shoal. It is an offshore maritime feature located in the exclusive economic of the Philippines, less than 200 nautical miles from the Philippine Island of Palawan, and almost 600 nautical miles from China’s Hainan Island. A […]
China’s brazen interference in a routine resupply mission to a Philippine outpost reveals Beijing’s growing capability to act on developments that it thinks may impact its interests—expansively defined—in the contested South China Sea. On November 16, two Philippine civilian boats delivering provisions to the moored BRP Sierra Madre at Second Thomas Shoal (called Ayungin Shoal […]
Three years into his quiescent China policy, Philippine president Rodrigo Duterte is experiencing a rude awakening in the South China Sea. The ongoing Chinese siege of the Philippines’ largest land feature in the Spratlys, Thitu Island, represents Duterte’s greatest foreign policy crisis and, ironically, the very country he has courted assiduously is at the heart […]
Scarborough Shoal is a rock in the South China Sea, approximately 120 nautical miles west of the Philippine island of Luzon. There are no structures built on Scarborough Shoal, but the feature is effectively controlled by China, which has maintained a constant coast guard presence at the feature since 2012.
Second Thomas Shoal is a submerged reef located in the Spratly Islands. The Philippines first took possession of the feature in 1999. The Philippine outpost on Second Thomas Shoal is the BRP Sierra Madre, a Philippine Navy transport ship intentionally grounded on the reef and maintained by a contingent of marines. The Sierra Madre can be seen below in the detail gallery.
Investigator Shoal is a low-tide elevation located in the Spratly Islands. Malaysia first took possession of the feature in 1999.
In May 2013, China increased its presence near a Philippine outpost in the South China Sea. Chinese coast guard and other vessels were spotted only a few miles from Second Thomas Shoal. Since 1999, Philippine marines have occupied a dilapidated warship—the BRP Sierra Madre—atop this coral atoll in the disputed Spratly Islands. Manila’s foreign affairs department protested the onset of continuous Chinese patrols, calling them “provocative and illegal.” Other leaders acknowledged that Beijing could not be lawfully denied freedom of navigation around the reef, but still feared for the safety of Manila’s supply lines to its dilapidated garrison.
Scarborough Shoal is widely seen as the most palpable erosion of stability in the South China Sea since 2012. Three conclusions about the standoff, especially its initial stages, highlight opportunities to better manage disputes in the years ahead.
Philippine president Rodrigo Duterte’s recent trip to Beijing yielded a number of agreements, including a vaguely-worded commitment to peacefully resolve the South China Sea disputes. But there was no public breakthrough on one closely-watched topic: the ability of Filipino fishermen to return to Scarborough Shoal. An international tribunal ruled on July 12 that China’s closure of the shoal to Philippine fishing was illegal. But in the lead-up to Duterte’s visit, Filipino fishermen complained that it was becoming more, not less, difficult for them to approach Scarborough. Recent satellite imagery supports this conclusion.
Transforming Scarborough into an artificial island-fortress could be the endgame in China’s rush to establish and consolidate control over the South China Sea.
The South China Sea is likely to persist as a source of tension both between China and its Southeast Asian maritime neighbors, and between China and the United States in 2015. China’s land reclamation activities, which are taking place at six of the seven reefs under Chinese control in the Spratly Island chain, will advance […]
The China Coast Guard (CCG) remains the dominant state actor in disputed waters of the South China Sea. Analysis of AIS data from commercial providers MarineTraffic and Starboard Maritime Analytics show that the CCG continued to maintain daily patrols at key features across the South China Sea in 2023. Taken together with the CCG’s leadership […]
China’s maritime militia, once a shadowy and ill-understood actor in the South China Sea disputes, has become visible to international observers in a very tangible way over the last year. Increasing numbers of militia vessels have been involved in collisions and tensions with the Philippines at Second Thomas Shoal, and their close coordination with the […]

In May, the Philippines and China took turns installing buoys in the disputed Spratly Islands. The deployment of buoys and other sovereignty markers in the South China Sea has a long history. But amid a flurry of new activity by the Philippines, including publicized patrols and surveillance missions, it is noteworthy that the buoy deployment […]
China Coast Guard patrols near oil and gas projects in the South China Sea have triggered responses from Vietnamese law enforcement and the Malaysian navy in two separate incidents over the last month. Contested Patrols at Nam Con Son and Vanguard Bank Chinese and Vietnamese law enforcement vessels had an extremely close encounter on March […]
China’s coast guard presence in the South China Sea is more robust than ever. An analysis of automatic identification system (AIS) data from commercial provider MarineTraffic shows that the China Coast Guard (CCG) maintained near-daily patrols at key features across the South China Sea in 2022. Together with the ubiquitous presence of its maritime militia, […]
This article is part of Evolving Threats to Southeast Asia’s Maritime Security, a series of analyses produced by experts convened by the S. Rajaratnam School of International Studies. How have the threats associated with interstate disputes evolved over the last 20 years? Most territorial and maritime disputes between Southeast Asian states seem to have stabilized […]
Analysis of satellite imagery from the past year shows that hundreds of Chinese militia vessels continue to operate in the Spratly Islands on a daily basis. The data confirms the massive scale of militia force in the Spratlys. It also shows a marked consistency in their movement and behavior patterns despite outcries from other claimants: […]
Automatic Identification System (AIS) data suggests that a Philippine government vessel was again denied access to Second Thomas Shoal by the China Coast Guard (CCG) in late June, underscoring the vulnerability of the grounded BRP Sierra Madre, which serves as a Philippine outpost on the reef. The Philippines’ M/V DA BFAR, a 60-meter research vessel […]
Cambodian prime minister Hun Sen kicked off his rotational chairmanship of the Association of Southeast Asian Nations (ASEAN) with characteristic “cowboy diplomacy.” Just months after the regional organization disinvited Myanmar’s junta leaders from regional meetings due to the lack of progress on the implementation the “Five Point Consensus”, the Cambodia leader became the first head […]
Over the past year, the Asia Maritime Transparency Initiative and the Center for Advanced Defense Studies conducted a study of China’s maritime militia using remote sensing data and open-source Chinese language research. The resulting report, Pulling Back the Curtain on China’s Maritime Militia, features the most comprehensive study to-date of the structure, subsidies, and ownership […]
Since early June, China Coast Guard (CCG) vessels have been contesting new Malaysian oil and gas development off the coast of Sarawak. The activity coincides with a patrol by Chinese military planes near Malaysia, which prompted scrambles by Malaysian aircraft and recriminations from Kuala Lumpur. This is at least the third time since last spring […]
Five years after an international arbitration court in the Hague ruled that the majority of China’s maritime claims in the South China Sea had no legal basis or validity, much has changed in the regional environment—but not in a positive way. The tribunal award had been expected to exert global diplomatic pressure on China to […]
On March 20, the Philippines announced that it had monitored over 220 Chinese militia boats at Whitsun Reef in a patrol earlier that month. In the two and a half months since, the Philippines has increased the level of its law enforcement and military patrols in the South China Sea beyond anything seen in recent […]
On March 20, Secretary of National Defense Delfin Lorenzana officially informed the Philippine nation about the presence of around 220 Chinese fishing vessels moored in line at Whitsun Reef (called Julian Felipe Reef in the Philippines). The reef is a wide boomerang-shaped shallow coral reef at the northeast end of Union Banks, located approximately 175 […]
Whitstun Reef, named Julian Felipe Reef in the Philippines after the late composer of the Philippine national anthem, is becoming a new flashpoint in the South China Sea. The massing of about 220 Chinese fishing vessels in the reef in the past several weeks raises worries about China’s growing activities in the contested sea. The […]
If there is a single phrase that best captures President-elect Joseph Biden’s still-nebulous foreign policy doctrine, it is this: “America is back”. In one of his most revealing interviews since the November elections, the incoming U.S. president made it clear that under his administration, “America’s going to reassert its role in the world and be […]
The Covid-19 pandemic has had no discernible effect on the presence of the China Coast Guard (CCG) in the South China Sea. An analysis of Automatic Identification System (AIS) data collected by MarineTraffic demonstrates that Beijing has continued to deploy its coastguard around symbolically important features at the edges of the nine-dash line on an […]
