Us Navy destroyer came within 12 nautical miles of the Chinese claimed area of the South China Sea.
The operation came as President Donald Trump’s administration seeks Chinese cooperation in dealing with North Korea’s missile and nuclear programs and could complicate efforts to secure a common stance.
The officials, speaking on condition of anonymity, said the USS John S. McCain traveled close to Mischief Reef in the Spratly Islands, among a string of islets, reefs and shoals. China has territorial disputes with its neighbors over the area.
It was the third “freedom of navigation operation” or “fonop” conducted during Trump’s presidency. Neither China’s defense ministry nor its foreign ministry immediately responded to a request for comment.
