U.S. bombers challenged China's recently established Air Defense Identification Zone (ADIZ) in the East China Sea, according to the Wall Street Journal.
In a report citing U.S. defense officials, the WSJ said that American B-52 bombers flew over the disputed Senkaku/Diaoyu Islands on Monday without informing Beijing ahead of time. The report said that the bombers took off from Anderson Air Force Base in Guam and entered into China's new ADIZ around 7 PM local time on Monday. They were not armed or accompanied by any escort planes.
America maintained that the B-52s flight was part of a long-planned exercise called Coral Lightning.
Still, the flight represented a clear challenge to China, which announced it was establishing an East China Sea Air Defense Identification Zone (ADIZ) on Saturday morning. It later said that Chinese planes had begun patrolling the area.
