Japan's Ministry of Defence (MoD) on 11 June said that two Chinese Su-27 'Flanker' fighter aircraft had flown very close to Japan Self-Defense Forces aircraft over the East China Sea for the second time in less than a month.

According to MoD officials, a People's Liberation Army Air Force Su-27 flew to within 30 m of a Japan Air Self-Defense Force YS-11EB electronic intelligence aircraft at around 11.00 am-12.00 pm local time on 11 June.

At around the same time, another Su-27 fighter flew to within 45 m of a Japan Maritime Self-Defense Force Kawasaki OP-3C reconnaissance aircraft. Neither of the Japanese aircraft suffered any damage.
