Beijing: China today said several Japanese aircraft entered its Air Defense Identification Zone over the East China Sea and carried out extensive reconnaissance amid increasing maritime tensions between the two countries.
Chinese planes conducted necessary tracking and monitoring of the foreign military planes, said Chinese Air Force spokesman Shen Jinke.
Japan along with US and South Korea declined to recognise China`s Air Defense Identification Zone (ADIZ) established last year artound the disputed islands.
The Japanese F-15 aircraft yesterday twice attempted to approach Chinese planes that were conducting a routine patrol in the ADIZ, and the Chinese planes took "reasonable, proper and restrained" measures to cope with the threat in the airspace, Shen said.
He reaffirmed that the establishment of the ADIZ is a purely defensive move to safeguard national security, normal order and the?safeguarding the?national security.
Chinese and Japanese ships have aggressively patrol the islands in the East China Sea, asserting their control over them.
