|China's "East China Sea Air Defense Zone."|
China's defense ministry spokesman Yang Yujun says, "China will establish other Air Defense Identification Zones at the right moment after necessary preparations are completed."
The statement is included in a Q&A published on the defense ministry's website.
The ministry also published a map of what China calls its "East China Sea Air Defense Identification Zone."
China says no nation should feel threatened by China's establishment of the ADIZ. But the sudden, unilateral move is viewed by China's neighbors and the United States as an attempt to change the regional status quo--power relations among nations. Reason: the ADIZ overlaps Japan’s air defense zone and includes a chain of uninhabited islands--known as the Senkaku in Japan and the Diaoyu in China--which Japan administers and China claims.
