TOKYO (Reuters) - Japanese military airplanes have conducted routine surveillance missions over disputed islands in the East China Sea without informing China, despite Beijing establishing a new airspace defence zone in the area this week, a top Japanese government official said on Thursday.
"They are carrying out surveillance activity as before in the East China Sea, including the zone," Chief Cabinet Secretary Yoshihide Suga told a regular news conference, adding that there had been no particular response from China.
