When he gave field guidance to the then Hwanghae Iron Plant, Chairman Kim Jong Il stopped at a workshop.

Infinitesimal dust was floating in the workshop.

The Chairman told officials that it was of no use if it did damage to smelters’ health, no matter how effective the metallurgical process based on domestic raw materials might be.

The Chairman earnestly told them that, though steel was valuable to the country, smelters’ health was much more valuable than steel and therefore, smelters should be considered before molten iron.
