China strongly condemned the United States after a US warship deliberately sailed near one of the Beijing-controlled islands in the hotly contested South China Sea to exercise freedom of navigation and challenge China's vast sea claims. The missile destroyer USS Curtis Wilbur sailed within 12 nautical miles (22 kilometers) of Triton Island in the Paracel chain "to challenge excessive maritime claims of parties that claim the Paracel Islands," without notifying the three claimants beforehand, Defense Department spokesman Mark Wright said on Saturday in Washington. China, Taiwan and Vietnam have overlapping claims in the Paracels and require prior notice from ships transiting what they consider their territorial waters. The latest operation was particularly aimed at China, which has raised tensions with the US and its Southeast Asian neighbors by embarking on massive construction of man-made islands and airstrips in contested waters. Vietnamese Foreign Ministry spokesman Le Hai Binh said that Vietnam respects "innocent passage" of ships through territorial waters in line with international law. State media quoted Binh as reiterating Vietnam's sovereignty over the Paracels and Spratlys and calling on nations to actively and practically contribute to peace and stability in the South China Sea. The US has claimed the attempts to restrict navigational rights by requiring prior notice are inconsistent with international law and pledged to regularly carry out similar maneuvers. In October, another US warship sailed in the nearby Spratly Islands near Subi Reef, where China has built one of seven artificial islands. The latest operation also drew Beijing's ire. Defense Ministry spokesman Yang Yujun issued a statement saying the "unprofessional and irresponsible" US action "severely violated Chinese law, sabotaged the peace, security and good order of the waters, and undermined the region's peace and stability." — AP
