Iedo reef

韓国国防省は８日、韓国の防空識別圏を南方に拡大すると発表しました。韓国が中国と管轄権を争う東シナ海の岩礁上空を含むことになり、日中韓の防空識別圏が一部重なることになりました。その岩礁がIedo reef（離於島：イオド、中国名 蘇岩礁）。韓国名では島になっていますが、なぜでしょう。とにかくこれも覚えておきましょう。（UG）

S. Korea follows China, expands air defense zone in East China Sea

South Korea said Sunday it has decided to expand its air defense zone over the East China Sea, overlapping the airspace of a new air defense zone China set up last month.

A spokesman for the South Korean Ministry of National Defense said the expanded South Korean air defense zone will take force on Dec. 15.

The expanded zone covers the airspace over the South Korean-claimed Iedo reef in the East China Sea, overlapping the airspace in that area under the air defense zone China established on Nov. 23.

The submerged reef, which lies within the overlapping economic zones of China and South Korea, is also claimed by China.

The airspace over Iedo also lies within Japan's own air defense zone.
