South Korea has retaliated against Japanese trade measures by removing the country from its white list of automatically approved export partners.

The move is presumably in retaliation against Japan, which took South Korea off its similar list of approved destinations for strategic materials 10 days ago. This comes despite a public gesture, late last week, from Japanese industry minister Hiroshige Seko, showing that Japan was willing to wave exports across. He told reporters last week that the South Korean government calling its export measures a "ban" was unjust.
