ABOARD A U.S. MILITARY AIRCRAFT - US Defense Secretary Ash Carter, in Washington's latest challenge of Chinese land reclamation in the South China Sea, said the scale of Beijing's activities, not the United States, was altering the status quo in the region.
Carter, speaking to reporters at the start of a 10-day trip to Asia, said the United States was trying to maintain a shared regional security structure that had advanced "prosperity for everyone" over the past 70 years.
"We've been flying over the South China Sea for years and years and years, and ... will continue to do that: fly, navigate, operate. So that's not a new fact," Carter said.
"The new facts are the reclamation and the scale on which it is being done, and that's not an American fact, that's a Chinese fact," Carter said.
The United States has publicly highlighted Chinese island-building in the disputed Spratly Islands several times in recent weeks. Carter called for an end to the land reclamation work by China and other countries on Wednesday and a halt to the militarization of the territorial dispute.
The U.S. Navy last week sent a reconnaissance plane carrying Navy and television camera crews to film the Chinese dredging work, which U.S. officials say has added some 2,000 acres to five outposts in the resource-rich Spratlys, including 1,500 this year.
The Spratlys are claimed by half a dozen countries, including the Philippines, Malaysia, Vietnam and China.
Chinese Foreign Ministry spokeswoman Hua Chunying deflected criticism, saying it was the Philippines that had conducted large-scale construction activities on what she said were China's islands and reefs since the 1970s, saying China would not "recognize the illegal occupation".
"We urge the Philippines to stop making erroneous remarks and we also urge the United States, which is not a party to the South China Sea dispute, to take a responsible attitude, be prudent in words and deeds, be reasonable and calm, and stop making provocative remarks," she told a news conference.
"These types of remarks are not conducive to solving the dispute peacefully, but will further damage the region's peace and stability."
Carter, asked whether the United States would send ships to within 12 miles of the Chinese-built islands to demonstrate Washington does not accept Beijing's territorial claims, said, "The United States will ... fly, sail, operate, wherever international law allows."
He also rejected the notion that the islands, which China built on previously submerged reefs, could claim 12 miles of territorial waters.
"The 12 nautical miles that I think you're referring to does not pertain to features that were submerged and now are no longer submerged," Carter said. (Additional reporting by Sui-Lee Wee in BEIJING; Editing by Chizu Nomiyama and Clarence Fernandez)
