South Korea announces expanded air defence zone

[mhm]

South Korea has announced it is expanding its air defence zone, which will now partially overlap with a similar zone announced by China.

The two zones will now both include a rock claimed by both countries and controlled by South Korea.

The defence ministry said it would co-ordinate with "related countries".

China announced a new Air Defence Identification Zone (ADIZ) last month, in a move that raised regional tensions.
