BEIJING - Chinese state-run media Friday identified Japan as Beijing's "prime target" in its newly declared air defence zone, calling for "timely countermeasures without hesitation" if Tokyo defies it.
However, other countries which have sent military aircraft into the air defence identification zone (ADIZ), including the United States and South Korea, should be largely ignored, the Global Times said.
"We should carry out timely countermeasures without hesitation against Japan when it challenges China's newly declared ADIZ," the paper, which is close to China's ruling Communist party, said in an editorial.
China's ADIZ which was declared on Saturday requires aircraft to provide their flight plan, declare their nationality and maintain two-way radio communication, or face "defensive emergency measures".
The zone overlaps those declared by Japan and South Korea, and includes airspace over East China Sea islands disputed with Tokyo.
The move triggered US and Japanese accusations of provocation, and criticism from South Korea and Australia.
Tokyo and Seoul said Thursday they had defied the zone with military overflights, showing a united front after Washington sent B-52 bombers through the airspace.
