Satellite images reveal floating barrier at mouth of disputed atoll in South China Sea

China claims almost the entire South China Sea, a conduit for more than US$3 trillion in annual ship commerce. Its territorial claims overlap with those of the Philippines, Vietnam, Malaysia and Brunei.

“What we are seeing at the Scarborough Shoal now is likely the beginning of Beijing’s pushback against Manila’s pushback,” said Ian Storey, a senior fellow at Singapore’s ISEAS-Yusof Ishak Institute.

Since President Ferdinand Marcos Jr took office in June 2022, the Philippines has challenged China’s presence at Scarborough and its attempts to stop the resupply of Filipino troops stationed at Second Thomas Shoal, he said.

“China’s attempts to prevent Filipino fishermen from fishing at Scarborough Shoal is absolutely illegal,” Storey said. “The 2016 arbitral tribunal ruling gave fishermen from both countries the right to (fish there). Manila is merely supporting the legitimate rights of Filipino fishermen.”

The shoal is coveted for its bountiful fish stocks and a stunning turquoise lagoon that provides a safe haven for vessels during storms.

The Chinese removed the barrier a few hours after the BFAR vessel left, Tarriela said. It was not clear from the photos how robust the barrier was and whether it would have posed an obstacle to larger warships.

In an article on Sunday, state-media outlet Global Times said “the Philippines has abused and unilaterally sabotaged the foundation of Beijing’s goodwill to Manila” that allowed Philippine fishermen to operate nearby, by working against China’s sovereignty and jurisdiction.

“If such provocations persist, China could be forced to take more effective measures to control the situation,” the article said, citing experts.
