BEIJING, Sha'ban 17, 1435, Jun 15, 2014, SPA -- China summoned Japan's defence attache on Friday to lodge a protest after the two countries traded accusations over the conduct of military jets above disputed waters, Reuters quoted the Defence Ministry as saying on Saturday. Tensions flared between Asia's two largest economies last week, when each country accused the other of flying military aircraft too close to its own jets. Tokyo lodged a protest on Wednesday, when Japan said Chinese fighter jets flew "abnormally close" to Japanese military aircraft over the East China Sea, a charge Beijing rejected. On Thursday, China said two Japanese F-15 planes followed a Chinese Tu-154 aircraft, coming as close as 30 metres, "seriously affecting China's flight safety". It posted a video allegedly showing the incident on the defence ministry website, but Japanese officials said China's assertion was not true. --SPA 13:50 LOCAL TIME 10:50 GMT www.spa.gov.sa/w
