Japanese and South Korean military aircraft have defied China’s air defence identification zone declared at the weekend, their governments said Thursday.
Japan said aircraft of its Self-Defense Force flew a patrol through the zone this week.
“We are conducting our surveillance activities as usual in the East China Sea, including the airspace concerned,” Chief Cabinet Secretary Yoshihide Suga told reporters, adding “we haven’t detected any signs,” of a response from China.
The South Korean air force flew through the zone this week on a routine manoeuvre, military sources were quoted by Yonhap News Agency as saying. China said it had monitored the flight.
