I'd guess this is not the case for India, where I believe that most 
folk educated enough to run an ISP probably have suitable levels of 
English language education, but in China and Korea there is definitely 
a language issue.

If abuse complaints direct to ISPs in those countries (and perhaps 
CC'ed to their upstream, which being bigger is more likely to have 
better foreign language skills) draw a blank, consider CC'ing the 
national CERTs on your "re-complaint".
