The B-52 Stratofortress is an American strategic bomber designed and built by Boeing and operated by the US Air Force since the 1950s.
According to reports, the bombers passed the Miyako Strait, a waterway between Japan’s Miyako Island and Okinawa Island, before flying over parts of the East China Sea near Taiwan’s coastal waters and areas claimed by China. The B-52s activated their automatic dependent surveillance broadcast systems to make their presence and flight route known, Asia Times reported, citing Taiwanese news outlets.
However, despite the reports, Taiwan’s Defense Ministry has not provided any confirmation of whether the US warplanes flew over parts of the East China Sea.
In March, two B-52H Stratofortress bombers flew over the East China Sea for an "integration training" mission by the US Navy and the Japan Air Self Defense Force. One month later, two B-52s reportedly flew around within 250 kilometers of the coastline of Guangdong, a province of southeast China, and circled above the Pratas Islands controlled by Taiwan before heading back to Guam.
The South China Sea contains many islands, reefs and shoals presently controlled and occupied by the People’s Republic of China but also claimed by several other nations, including Vietnam, Taiwan, Cambodia, Brunei and the Philippines. Aside from the enormous amount of international sea trade that passes through the area, it is also believed to contain large amounts of as-yet unexplored oil and natural gas deposits.
China, Japan and South Korea are not in agreement over their exclusive economic zones - which grant countries rights to use marine resources - in the East China Sea.
