According to an article in the Korean Herald, South Korea posted its first-ever "cultural trade surplus." This is a very interesting perspective. It's interesting to think about. It's interesting that Koreans are interested in it. They take the idea of being successful cultrual imperialists quite seriously, as a component of their "arrival" in the world as a "developed" country.
The idea, basically: Korea now exports more cultural stuff (books, movies, music, etc.) than it imports, on a dollar-value basis. There aren't many countries that do this – the US is the juggernaut, of course; there's probably some others: France, I suspect, and Japan, and Italy. I'd bet on maybe Egypt, actually, and maybe Brazil. But these are just guesses. Completely wild guesses. I'm too lazy to research it. But it's interesting, anyway.
