With all eyes on North Korea after President Trump promised “fire and fury,” the U.S. Navy quietly dispatched a warship to sail by one of China’s artificial islands in the South China Sea.

FOX’s Lucas Tomlinson has the details from the Pentagon:

It’s the third time since President Trump took office the Pentagon ordered a Navy destroyer to challenge China’s territorial claims in the South China Sea.

USS John S. McCain sailed within 12 nautical miles of Mischief Reef, one of three Chinese man-made islands with a runway and military fortifications.

Similar U.S. military operations took place in May and July. 12 nautical miles from shore marks the territorial boundary for all nations.

This comes as the Trump administration has called on China to do more to reign in North Korea’s nuclear missile program.
