The US has seen Chinese activity around a reef China seized from the Philippines nearly four years ago that could be a precursor to more land reclamation in the disputed South China Sea, the US Navy chief said on Thursday.
The head of US naval operations, Admiral John Richardson, expressed concern that an international court ruling expected in coming weeks on a case brought by the Philippines against China over its South China Sea claims could be a trigger for Beijing to declare an exclusion zone in the busy trade route.
Richardson said the US was weighing responses to such a move.
China claims most of the South China Sea, through which more than US$5 trillion in global trade passes every year. Taiwan, Vietnam, Malaysia, Brunei and the Philippines have rival claims.
Richardson said the US military had seen Chinese activity around Scarborough Shoal (Huangyan Island, 黃岩島), in the northern part of the Spratly archipelago (Nansha Islands, 南沙群島), about 200km west of the Philippine base of Subic Bay.
“I think we see some surface ship activity and those sorts of things, survey type of activity, going on. That’s an area of concern... a next possible area of reclamation,” he said.
Richardson said it was unclear if the activity near the reef, which China seized in 2012, was related to the pending arbitration decision.
The Philippine Department of Foreign Affairs said it had yet to receive a report about Chinese activities in Scarborough Shoal.
A Philippine military official who declined to be identified because he is not authorized to speak to the media said he was unaware of a Chinese survey ship in the area.
“China already has de facto control over the shoal since 2012 and they always have two to three coast guard ships there. We are also monitoring their activities and movements there,” the official told reporters.
“There are no indications China will reclaim Scarborough Shoal,” the official said.
Richardson said China’s pursuit of South China Sea territory, which has included massive land reclamation to create artificial islands elsewhere in the Spratlys, threatened to reverse decades of open access and introduce new “rules” that required countries to obtain permission before transiting those waters.
He said that was a worry given that 30 percent of the world’s trade passes through the region.
Asked whether China could respond to the ruling by the court of arbitration in The Hague by declaring an air defense identification zone, or ADIZ, as it did farther north in the East China Sea in 2013, Richardson said: “It’s definitely a concern.
“We will just have to see what happens,” he said. “We think about contingencies and... responses.”
Richardson said the US planned to continue carrying out freedom-of-navigation exercises within 12 nautical miles (22.2km) of disputed South China Sea geographical features to underscore its concerns about keeping sea lanes open.
The US responded to the East China Sea ADIZ by flying B-52 bombers through the zone in a show of force in November 2013.
Richardson said he was struck by how China’s increasing militarization of the South China Sea had increased the willingness of other countries in the region, including Japan, India, South Korea, Vietnam and the Philippines, to work together.
