Korea's Hyundai Mipo Dockyard plans to offload KRW 318.3bn ($280m) of Hyundai Heavy Industries (HHI) stock to boost its finances.

The shipyard said it would sell 2.72m shares in a block trade to resolve circular shareholding issue and secure liquidity.

In June 2017 it decided to sell its near-8% stake in Hyundai Robotics.

That move was expected to raise as much as $329m.
