Last month, the National Task Force on the West Philippine Sea, an interagency body housed within the Presidential Office in Manila, reported that more than 200 Chinese militia vessels were anchored at Whitsun Reef. The task force released photos of some of those vessels, collected during a patrol by the Philippine Coast Guard on March […]

China’s new Coast Guard Law has drawn concern and criticism from the United States, Japan, the Philippines, and other regional governments, as well as academics. Passed by the National People’s Congress on January 22, the law contains strong language regarding the China Coast Guard’s (CCG) authority to prevent infringement of China’s sovereignty and maritime rights. […]

Vietnam continues to make modest improvements to its facilities in the Spratly Islands. In cooperation with Simularity, AMTI has reviewed satellite imagery from the last two years to catalog upgrades to Vietnam’s island outposts since the initiative last surveyed them. This exercise underscores Hanoi’s continuing focus on making its bases more resilient to invasion or […]

Since the global outbreak of Covid-19, the U.S. and Chinese governments have accused each other of using the pandemic as cover to increase military operations in the Indo-Pacific. The United States, for example, has pointed to China’s deployment of coastguard forces to challenge the oil and gas activities of other claimants in the South China […]

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 […]

The China Coast Guard (CCG) and Royal Malaysian Navy (RMN) are involved in another standoff over hydrocarbon exploration in the South China Sea. China Coast Guard ship 5402 harassed a drilling rig and its supply ships operating just 44 nautical miles from Malaysia’s Sarawak State on November 19. Malaysia deployed a naval vessel in response, […]

Another U.S.-built facility at Ream naval base has been demolished, as revealed by recent satellite imagery from Planet and Maxar. Before and after: Satellite imagery shows the Rigid-Hulled Inflatable Boat Maintenance Facility at Ream naval base was still standing on October 1 but had been completely dismantled by November 4. The National Committee for Maritime […]

On December 12, 2019, Malaysia made a partial submission to the UN Commission on the Limits of the Continental Shelf (CLCS) outlining the northern part of its purported extended continental shelf in the South China Sea. It set off a flurry of diplomatic notes from other claimants and interested parties. China lodged its objections the […]

Chinese investment in the Maldives is a frequent subject of concern. The archipelagic nation is strategically located along major Indian Ocean shipping routes. Its former president has very publicly speculated that China is being allowed to buy up whole islands and extend loans that the government cannot afford. And media articles in India, long the […]

The East China Sea disputes had settled into an uneasy status quo over the last few years, but tensions persist. Recent events suggest that the risk of violence is again growing. China’s maritime forces deployed around the contested Senkaku Islands have become more capable and more determined. In response, Japan is upgrading its ability to […]

China has deployed a network of sensors and communications capabilities between Hainan Island and the Paracel Islands in the northern South China Sea. These capabilities are part of a “Blue Ocean Information Network” (蓝海信息网络) developed by China Electronics Technology Group Corporation (CETC), a state-owned company, to aid in the exploration and control of the maritime […]

Updated 5/18/2020: Haiyang Dizhi 8 during survey operations off of Malaysia, May 4, 2020 The three-country standoff that began last December over Malaysian oil and gas exploration has escalated dramatically with the deployment of a Chinese survey ship and its escorts earlier this month. The game of chicken now playing out between Chinese and Malaysian […]

Marine research vessels have been making waves in the Indo-Pacific recently. This is especially true of China’s large fleet. State-owned Chinese vessels have engaged in oil and gas surveys on the continental shelves of its neighbors, as the Haiyang Dizhi 8 did off the coast of Vietnam for four months last year. Others have conducted […]

China has maintained an almost constant militia presence around Thitu Island, the largest of the Spratly Islands occupied by the Philippines, for over 450 days according to satellite imagery analyzed by AMTI. China first deployed militia vessels around Thitu in December 2018 in response to Philippine efforts to repair the island’s runway and undertake other […]

A months-long standoff over oil and gas operations in the South China Sea is playing out between Malaysian, Chinese, and a small number of Vietnamese vessels, though all three governments are keeping the episode out of the public eye. At issue are two oil and gas fields that Malaysia’s state-owned Petronas is exploring on the […]

For several weeks starting in late December, Indonesian media was dominated by reports of a flotilla of Chinese fishing and coast guard vessels operating without permission in the country’s exclusive economic zone (EEZ). The situation strained bilateral relations, presented President Joko “Jokowi” Widodo with the first foreign policy crisis of his second term, and forced […]

Updated December 13, 2019 The Chinese survey vessel Haiyang Dizhi 8 along with its coast guard and paramilitary escorts left Vietnam’s exclusive economic zone on October 23, ending a standoff with Vietnamese ships that began more than four months earlier. The de-escalation seems to have been in response to the departure a day earlier of […]

India has begun to invest heavily, albeit quietly, in expanding its naval and air power across the Indian Ocean. The effort is driven by two factors: a desire to improve maritime domain awareness and maritime security throughout the vast region, and New Delhi’s growing anxieties about Chinese inroads in its strategic backyard. As Chinese naval […]

In the middle of the night on June 9, Chinese fishing vessel Yuemaobinyu 42212 collided with Philippine fishing boat F/B Gem-Ver, which was riding at anchor near Reed Bank in the South China Sea. The Chinese ship fled the scene, leaving 22 Filipino fishers aboard a sinking Gem-Ver in peril until they were rescued by […]

China Coast Guard (CCG) vessels have been harassing a drilling rig operating in a Vietnamese oil and gas block near Vanguard Bank, an underwater feature in the South China Sea, since June. Meanwhile, a large contingent of CCG ships have since July been escorting the Chinese state-owned survey ship Haiyang Dizhi 8 operating off the […]

On July 12, 2016, an arbitral tribunal at the Permanent Court of Arbitration in The Hague issued its ruling in Manila’s case against Beijing’s claims in the South China Sea. Convened under the compulsory dispute settlement provisions of the United Nations Convention on the Law of the Sea (UNCLOS), the tribunal’s five arbitrators ruled overwhelmingly […]

After a sharp drop-off in activity from 2016 to late 2018, Chinese clam harvesting fleets have returned to the South China Sea in force over the last six months. These fleets, which typically include dozens of small fishing vessels accompanied by a handful of larger “motherships,” destroy vast swaths of coral reef in order to […]

AMTI explains the role of China’s Maritime Militia in this short explainer video featuring high-resolution imagery from Thitu Island and Loaita Cay:  Since early March, Chinese fishing vessels—apparently part of the country’s maritime militia force—have been operating near two Philippine-held features in the disputed Spratly Islands: Loaita Island and Loaita Cay, called Kota and […]

Vietnam continues to quietly upgrade its facilities in the Spratly Islands, though apparently without facing the same reaction from China’s maritime militia forces as the Philippines recently has. Vietnam occupies 49 outposts spread across 27 features in the vicinity of the Spratly Islands. Of those 27 features, only 10 can be called islets while the […]

The steady pace of U.S. and now UK operations challenging China’s declared baselines around the Paracel Islands warrants just as much attention as other FONOPs, both because of the egregiousness of that claim and because of a fear that Beijing will soon declare similar baselines around the Spratlys.

China has responded to new Philippine construction on Thitu Island by deploying a large fleet of ships from Subi Reef, just over 12 nautical miles away. These include several People’s Liberation Army-Navy (PLAN) and China Coast Guard (CCG) ships, along with dozens of fishing vessels ranging in size from 30 to 70 meters.

The security implications of the South China Sea receive significant attention, but too little attention has focused on a key set of actors in the South China Sea—the fishers who serve on the front lines of this contest. Those fishers face a dire threat to their livelihoods and food security as the South China Sea fisheries teeter on the brink of collapse. A six-month-long project undertaken by CSIS and Vulcan, Inc. tells a worrying story about the scale of unseen fishing activity in the region, massive overcapacity in the Spratlys, and the stunning scale and expense of China's maritime militia.

The Pacific Islands are emerging as yet another arena of competition between China, the United States, and other powers. In response, Australia, the United States, and New Zealand have refocused economic and diplomatic efforts in the region.

Recent satellite imagery of Bombay Reef in the Paracel Islands shows that China has installed a new platform at the largely untouched South China Sea feature. The development is interesting, given Bombay Reef’s strategic location and the possibility that the structure’s rapid deployment could be repeated in other parts of the South China Sea.

CSIS’s newly-launched working group on the South China Sea seeks consensus on realistic, actionable steps that claimant states and interested parties could take to boost cooperation and manage tensions at sea. The group meets regularly to tackle issues that it considers necessary for the successful management of the South China Sea disputes and produces blueprints for a path forward on each. Through this iterative process, the group hopes to produce a robust model for managing the disputes that would be both legally and politically feasible—in effect, a blueprint for an eventual code of conduct.
