I believe the answer is:

korean

I'm a little stuck... Click here to teach me more about this clue!

'asian' is the definition.
(someone from North or South Korea)

I don't understand how the remainder of the clue works.

(Other definitions for korean that I've seen before include "One is from Seoul, say" , "Asian language" , "From Seoul or Pyongyang?" , "Eg, from Seoul" , "From Pyongyang, perhaps" .)

I've seen this clue in The Independent.
