WASHINGTON – The United States has seen Chinese activity around a reef that 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 U.S. Navy chief said Thursday.
The head of U.S. naval operations, Adm. 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 told Reuters the United States was weighing responses to such a move.
He said the U.S. military had seen Chinese activity around Scarborough Shoal in the northern part of the Spratly archipelago, about 200 km 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.
He 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 United States planned to continue carrying out what it calls “freedom-of-navigation” exercises within 12 nautical miles (22 km) of disputed South China Sea geographical features to underscore its concerns about keeping sea lanes in the region open.
The United States 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 to work together, not just bilaterally, but also multilaterally.
India and Japan joined the U.S. Navy in the Malabar naval exercise since 2014, and were slated to take part again this year in an even more complex exercise that will take place in an area close to the East and South China Seas.
South Korea, Japan and the United States were also working together more closely than ever before, he said.
Richardson said the United States would welcome the participation of other countries in joint patrols with the United States in the South China Sea, but those decisions needed to be made by the countries in question.
He said the U.S. military sees good opportunities to build and rebuild relationships with countries such as Vietnam, the Philippines and India because, he added, those nations have all realized the importance of safeguarding the freedom of the seas.
He cited India’s recent hosting of an international fleet review that included 75 ships from 50 navies, and said the United States was exploring opportunities to increase its use of ports in the Philippines and Vietnam, among others.
These could include the former naval base at Vietnam’s Cam Ranh Bay, which has hosted both Soviet and American forces at separate points in history.
But he said Washington needed to proceed judiciously rather than charging in “very fast and very heavy,” given the enormous influence and importance of the Chinese economy in the region.
“We have to be sophisticated in how we approach this so that we don’t force any of our partners into an uncomfortable position where they have to make trade-offs that are not in their best interest,” he said.
“We would hope to have an approach that would . . . include us a primary partner but not necessarily to the exclusion of other partners in the region,” he said.
