SYDNEY/HONG KONG (Reuters) – Vietnam has begun dredging work on a disputed reef in the South China Sea, satellite imagery shows, the latest move by the Communist state to bolster its claims in the strategic waterway.
Activity visible on Ladd Reef in the Spratly Islands could anger Hanoi’s main South China Sea rival, Beijing, which claims sovereignty over the group and most of the resource-rich sea.
Ladd Reef, on the southwestern fringe of the Spratlys, is completely submerged at high tide but has a lighthouse and an outpost housing a small contingent of Vietnamese soldiers. The reef is also claimed by Taiwan.
In an image taken on Nov. 30 and provided by U.S.-based satellite firm Planet Labs, several vessels can be seen in a newly dug channel between the lagoon and open sea.
While the purpose of the activity cannot be determined for certain, analysts say similar dredging work has been the precursor to more extensive construction on other reefs.
“We can see that, in this environment, Vietnam’s strategic mistrust is total … and they are rapidly improving their defenses,” said Trevor Hollingsbee, a retired naval intelligence analyst with Britain’s defense ministry.
“They’re doing everything they can to fix any vulnerabilities – and that outpost at Ladd Reef does look a vulnerability.”
Reuters reported in August that Vietnam had fortified several islands with mobile rocket artillery launchers capable of striking China’s holdings across the vital trade route.
Vietnam’s foreign ministry did not respond to a request for comment.
