The Chinese military has released footage of its H-6K bomber being intercepted by F-16s. Although the aircraft is blur out, the paint scheme of the F-16 is still discernible to rule out as the Mitsubishi F-2.
The Taiwanese media reports that the jets are from the Republic of China Air Force.
The F16 paint scheme is in the traditional grey scheme. The close up shows unique tail flash design synonymous with ROCAF markings not JASDF. Can make out the extended tail parachute to the tail too.
The F-16’s are clearly A’s Block 20 from the ROCAF.
