Aug. 28 (UPI) -- A U.S. B-52H bomber recently entered China's Air Defense Identification Zone in areas of the East China Sea, according to a Taiwanese press report.
The Liberty Times reported Tuesday a strategic bomber entered areas of the East China Sea where Chinese activities have been ongoing as a check against Taiwan and Japan.
Using data from Aircraft Spots, the site that tracks military air movements online, the report said two B-52H bombers left from Andersen Air Force Base in Guam on Tuesday and flew across the Bashi Channel to reach the South China Sea.
The bombers were accompanied by a KC-135 Stratotanker, a military aerial refueling aircraft.
The bombers were refueled during operation, according to the report.
A separate B-52H bomber left Guam for areas near Okinawa last Thursday, then entered China's air defense identification zone in the East China Sea, before returning to Guam.

Chinese state tabloid Global Times has denounced the flights.
Chinese media described the action as irresponsible and said the move disrupts regional stability.
Chinese experts said the B-52H bombers might have conducted target practice during flight, including "hitting" a Chinese aircraft carrier with an anti-ship missile.
In June, China also slammed the United States for flying a pair of B-52 bombers near disputed islands in the South China Sea.
China has recently increased the number of military drills it conducts near Taiwan, to warn Taipei and Washington.
