Other than economical companies I don't see any others. Here is a list:
Korea Ferrous Metals Export & Import Corporation (steel, mining)
Korea General Zinc Industry Group (non-ferrous metals, mining)
Korea General Chemicals Trading Corporation (chemical group, plastics)
Korea General Machinery Trading Corporation (machine tools, hydroelectrics)
Korea Kwangmyong Trading Group (shipping)
Korea Ponghwa General Corporation (light industrial group, clothing, rucksacks, bags)
Korea Unha General Trading Corporation (import/export, textiles)
Korea General Petroleum United Corporation (petroleum refining, downstream products)
And the list goes on..so no..those don't look any familiar to the degree of a Hyundai or a Samsung.
