Officers’ union Nautilus International says it has had a “positive response” from International Maritime Organisation (IMO) secretary-general Koji Sekimizu after it called for action to ensure that countries comply with guidelines on fair treatment of seafarers following the Sewol disaster.

Nautilus head Mark Dickinson had written to Sekimizu and the South Korean embassy to express his concern over the way Captain Lee Joon Seok and the ship’s crew were treated following the 15 April accident.
