Where is South Korea in relation to the buyers for its steel? Would it travel to market by land or sea? Do it have to go far?

What’s the climate like where the steel is milled and shipped? How might the climate impact production or shipping? Consider stress to machinery due to heat, cold, humidity; bad roads due to rain, snow; washed-out roads due to earthquake, mudslide; heavy seas.

What natural resources are needed to make steel and move it to market?
