The nautical confrontation comes amid tensions between the world’s two largest economies over trade as well as an on-again-off-again North Korean summit.
China’s Ministry of Defense said in a statement that the entry of the U.S. warships was not permitted, and they have been warned to leave.
The Antietam, a guided-missile cruiser, and the Higgins, a destroyer, came within 12 nautical miles of the Paracel Islands, an archipelago in waters contested by China’s neighbors, according to the New York Times.
The chief spokesman for China’s Ministry of National Defense, Senior Col. Wu Qian, said the American military had “seriously violated China’s sovereignty, [and] undermined strategic mutual trust.”
The U.S. warships were carrying out “freedom of navigation” operations, also called FONOPS, which the Navy says are a means to challenge excessive maritime claims and uphold rights to use of the sea under international law. FONOPS are regularly conducted in disputed seas throughout the world.
A spokesman for the U.S. Navy’s Seventh Fleet, Cmdr. Clay Doss, told the Times that similar operations have been conducted in 22 countries. [FULL STORY]
