"Computer screens display a map showing the outline of China's new air defense zone in the East China on the website of the Chinese Ministry of Defense, in Beijing Tuesday. On Saturday Beijing issued a map of the zone — which includes a cluster of islands controlled by Japan but also claimed by China — and a set of rules that say all aircraft entering the area must notify Chinese authorities and are subject to emergency military measures if they do not identify themselves or obey Beijing's orders. Chinese characters in red in the center of the map at left reads: ""Air Defense Identification Zone in East China Sea."" Photo: Ng Han Guan"
