I saw this story a few days ago and filed it away in one of my mental cabinets. Fortunately, Page F30 wound up doing a translation of one of the recent articles on statistics demonstrating the yawning chasm between the economies of North and South Korea. Some of the most eye-catching facts:

GNI per capita for 2009:
South Korea $17,175
North Korea $960

Total trade 2009
South Korea $686.6 billion
North Korea $3.4 billion
(South Korean total trade 201.9 times North Korea)

Exports
South Korea $363.5 billion
North Korea $1.1 billion
(South Korean total exports 330.5 times North Korea)
