The Chinese People’s Liberation Army (PLA) is constructing a new counter-stealth radar system on a disputed reef in the South China Sea that would significantly expand its surveillance capabilities in the region, satellite imagery suggests.
Analysis by London-based think tank Chatham House suggests China is upgrading its outpost on Triton Island (Jhongjian Island, 中建島) on the southwest corner of the Paracel Islands (Xisha Islands, 西沙群島), building what might be a launching point for an anti-ship missile battery and sophisticated radar system.
“By constraining the US ability to operate stealth aircraft, and threaten stealth aircraft, these capabilities in the South China Sea send a powerful signal to US allies and partners in the region that the US advanced technologies may not be able to stand up to the PLA,” said Michael Dahm, a senior resident fellow at the Mitchell Institute for Aerospace Studies.

Similar counter-stealth radars, known as SIAR, or synthetic impulse and aperture radar, have been built to the south, on Subi Reef (渚碧礁) in the Spratly Islands (Nansha Islands, 南沙群島), and China’s Hainan Island, to the north.
The construction on Triton would close a gap in its coverage. “Triton Island is another brick in the wall,” Dahm said.
Triton, a reef of about 120 hectares, lies in the farthest southwest corner of the Paracels, an archipelago controlled by China since a violent conflict with Vietnam in 1974. It is also claimed by Taiwan and Vietnam.
Any construction on Triton — which is 135 nautical miles (250km) east of Vietnam’s mainland, and 170 nautical miles south of China’s Hainan — is likely to be of concern to Hanoi.
The structures on Triton would “significantly diminish [Vietnam’s] capacity to operate undetected in the area,” the analysis said.
“Alongside existing radar on Triton which can detect sea-going vessels, Beijing now has the potential to track Vietnamese air movements and gain forewarning of Hanoi’s maneuvers in the area, including efforts to access oil and gas deposits,” it said.
The radar might also complicate attempts by the US, the UK and Australian navies to navigate in the surrounding waters, it added.
A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps. The winner from Honor, a Chinese smartphone maker, completed the 21km race in 50 minutes and 26 seconds, said a WeChat post by the Beijing Economic-Technological Development Area, also known as Beijing E-Town, where the race began. That was faster than the human world record holder, Ugandan Jacob Kiplimo, who finished the same distance in about 57 minutes in March at the Lisbon road race. The performance by the robot marked a significant step forward
Four contenders are squaring up to succeed Antonio Guterres as secretary-general of the UN, which faces unprecedented global instability, wars and its own crushing budget crisis. Chile’s Michelle Bachelet, Argentina’s Rafael Grossi, Costa Rica’s Rebeca Grynspan and Senegal’s Macky Sall are each to face grillings by 193 member states and non-governmental organizations for three hours today and tomorrow. It is only the second time the UN has held a public question-and-answer, a format created in 2016 to boost transparency. Ultimately the five permanent members of the UN’s top body, the Security Council, hold the power, wielding vetoes over who leads the
South Korea’s air force yesterday apologized for a 2021 midair collision involving two fighter jets, a day after auditors said the pilots were taking selfies and filming during the flight and held them responsible for the accident. “We sincerely apologize to the public for the concern caused by the accident that occurred in 2021,” an air force spokesman told a news conference, adding that one of the pilots involved had been suspended from flying duties, received severe disciplinary action and has since left the military. The apology followed a report released on Wednesday by the South Korean Board of Audit and Inspection,
An earthquake registering a preliminary magnitude of 7.7 off northern Japan on Monday prompted a short-lived tsunami alert and the advisory of a higher risk of a possible mega-quake for coastal areas there. The Cabinet Office and the Japan Meteorological Agency said there was a 1% chance for a mega-quake, compared to a 0.1% chance during normal times, in the next week or so following the powerful quake near the Chishima and Japan trenches. Officials said the advisory was not a quake prediction but urged residents in 182 towns along the northeastern coasts to raise their preparedness while continuing their daily lives. Prime
