Japan and South Korea in row over mines that used forced labour

Seoul furious at Japanese bid for Unesco listing for Sado gold mine complex, which used slave labour in 1940s

Japan has set itself on a diplomatic collision course with South Korea by applying for Unesco world heritage status for gold and silver mines on an island off its west coast which used forced labour from Korea.

The row over the mines - on Sado island in the Sea of Japan - is expected to further sour relations between the countries just as the US is pressing them to present a united front against North Korea's nuclear programme.
