WASHINGTON (REUTERS) - China was carrying out land reclamation in contested waters of the South China Sea this month, more than four weeks after saying it had stopped such activity, a US expert said on Tuesday (Sept 15), citing recent satellite images.
The evidence of continued dredging in the Spratly archipelago could complicate a visit to the United States by Chinese President Xi Jinping next week, when US concerns about China's assertive pursuit of territorial claims in Asia are expected to be high on the agenda.
Bonnie Glaser, of Washington's Centre for Strategic and International Studies think tank (CSIS), said images taken in early September showed dredging activity at both Subi Reef and Mischief Reef in Spratlys.
The dredgers at Subi could be seen pumping sediment on to areas bordered by recently built sea walls and widening the channel for ships to enter waters enclosed by the reef.
At Mischief Reef, a dredger was expanding a channel to enable easier access for ships, possibly for future use as a naval base, Glaser said.
On Aug 5, Chinese Foreign Minister Wang Yi said Beijing had halted land reclamation in the South China Sea.
Glaser said China's activity appeared to be focused on construction for military use.
Images of Fiery Cross Reef showed a completed and freshly painted 3,000 metre runway, helipads, a radar dome, a surveillance tower and possible satellite communication facilities, she said.
Security experts say a 3,000 metre strip would be able to accommodate most Chinese military aircraft.
Glaser said China's apparent preparations to build similar airstrips on Subi and Mischief Reefs raised questions about whether it would challenge freedom of navigation in the air and sea in the future.
"The persistence of dredging, along with construction and militarization on China's artificial islands, underscore Beijing's unwillingness to exercise self-restraint and look for diplomatic paths to reduce tensions," she said.
"On the eve of President Xi Jinping's visit to the United States, Beijing appears to be sending a message to President Barack Obama that China is determined to advance its interests in the South China Sea even if doing so results in heightened tensions with the United States."
On Monday, Greg Poling, director of CSIS's Asia Maritime Transparency Initiative (AMTI), which obtained the images, said three airstrips in the Spratlys would allow China to threaten all air traffic over features it has reclaimed there.
China's Foreign Ministry maintains China has "indisputable sovereignty" over the Spratly Islands and has a right to establish military facilities there.
