A pair of American B-52 bombers flew unannounced into a recently established Chinese no-fly zone in the East China Sea, in a direct rebuke of Beijing’s asserted authority over the area.

The bombers, based out of Andersen Air Force Base in Guam, entered the contested airspace as part of a training operation dubbed Coal Lightning, according to The Wall Street Journal.

The aircraft were unarmed and were not escorted by American fighter jets, a defense official told the Journal.

“The planes flew a pattern that included passing through the [Air Defense Identification Zone],” the official said.

“The flight was without incident,” the official added.

Over the weekend, Chinese leaders instituted new rules for U.S. allied military aircraft operating in the skies above the Diaoyutai and Senkaku islands in the East China Sea.
