Not in the south, but in the north?I'm not sure what Korea would have in abundance that foreign nations would want (cotton, steel, coal, gold, rubber, etc)
North Korea contains the great bulk of all known mineral deposits on the peninsula. It is estimated that some 200 minerals are of economic value. Most important are iron ore and coal, although greater emphasis has been given to the extraction of gold, magnesite (magnesium carbonate), lead, and zinc. Other abundant minerals include tungsten, graphite, barite (barium sulfate), and molybdenum.
