China 'monitored' US bombers in new air zone

The air zone covers a group of disputed islands controlled by Japan

China monitored the flight of two US bombers that flew across its newly-declared "air defence identification zone", its defence ministry said.

The B-52 planes flew over disputed islands in the East China Sea on Tuesday without announcing themselves, defying new Chinese air defence rules.
China's ministry said it had "the ability to effectively manage and control the relevant air zone".
Japan and the US are strongly opposed to the air zone declared by China.
The US said it had followed "normal procedures" during the bombers' flight and had not filed flight plans with China.
China announced the establishment of the "air defence identification zone" on Saturday, and said aircraft passing through the zone must obey its rules, including identifying themselves, or face "emergency defensive measures".
However, Wednesday's defence ministry statement made no reference to any emergency measures.
