US warship challenges China's claims in South China Sea

A first under President Trump, USS Dewey cruises past artificial island built by Beijing in move likely to rile China.

    A US Navy warship sailed within 12 nautical miles of an artificial island built up by China in the South China Sea, the first such challenge to Beijing in the strategic waterway since US President Donald Trump took office.

    The US patrol, the first of its kind since October, marked the latest attempt to counter what Washington sees as Beijing's efforts to limit freedom of navigation in the strategic waters.

    US officials, speaking on condition of anonymity, said on Wednesday the USS Dewey traveled close to Mischief Reef in the Spratly Islands - among a string of islets, reefs and shoals over which China has territorial disputes with its neighbours.

    The move angered Beijing, which reiterated its position that China has "indisputable sovereignty" over the Spratly Islands and their surrounding waters.

    "The US military's action was showing off force, promoting regional militarisation and could have easily led to a sea or air incident," Ren Guoqiang, spokesman for China's defence ministry, said later on Thursday.

    "The Chinese army has expressed firm opposition and has lodged solemn representations with the US."

    The US navy's so-called "freedom of navigation operation" comes as Trump is seeking Beijing's cooperation to rein in ally North Korea's nuclear and missile programmes.

    Territorial waters are generally defined by UN convention as extending at most 12 nautical miles from a state's coastline.

    One US official said it was the first operation near a land feature that was included in a ruling last year against China by an international arbitration court in The Hague. The court invalidated China's claim to sovereignty over large swathes of the South China Sea.

    The US has criticised China's construction of man-made islands and build-up of military facilities in the sea and expressed concern they could be used to restrict free movement.

    US allies and partners in the region had grown anxious as the new administration held off on carrying out South China Sea operations during its first few months in office.

    Last month, top US commander in the Asia-Pacific region, Admiral Harry Harris, said the United States would likely carry out freedom of navigation operations in the South China Sea soon, without offering details.

    Still, the US military has a long-standing position that these operations are carried out throughout the world, including in areas claimed by allies, and they are separate from political considerations.

    The White House did not immediately comment on the latest action.

    OPINION: Why China cares about the South China Sea

    Under the previous administration, the US Navy conducted several such voyages through the South China Sea. The last operation was approved by then-president Barack Obama.

    China's claims to the South China Sea, which sees about $5 trillion in ship-borne trade pass every year, are challenged by Brunei, Malaysia, the Philippines, and Vietnam, as well as Taiwan.

    The latest US patrol is likely to exacerbate US-China tensions that had eased since Trump hosted Chinese President Xi Jinping for a summit at the US leader's Florida resort last month.

    Trump lambasted China during the 2016 presidential campaign, accusing Beijing of stealing US jobs with unfair trade policies, manipulating its currency in its favour, and militarising parts of the South China Sea.

    But since meeting Xi at his Mar-a-Lago resort, Trump has praised his counterpart's efforts to restrain North Korea, though Pyongyang has persisted with ballistic missile tests despite international condemnation.

    US-based South China Sea analyst Greg Poling, of the Center for Strategic and International Studies, said the operation was also the first conducted by the United States close to an artificial feature built by China not entitled to a territorial sea under international law.

    Previous freedom of navigation operations have gone within 12 nautical miles of Subi and Fiery Cross reefs, two other features in the Spratlys built up by China, but both of those features are entitled to a territorial sea.

    Mischief Reef was not entitled to a territorial sea as it was underwater at high tide before it was built up by China and was not close enough to another feature entitled to such a territorial sea, said Poling.

    He said the key question was whether the US warship had engaged in a real challenge to the Chinese claims by turning on radar or launching a helicopter or boat - actions not permitted in a territorial sea under international law.

    Otherwise, critics say, the operation would have resembled what is known as "innocent passage" and could have reinforced rather than challenged China's claim to a territorial limit around the reef.
