User blog comment:Hannadzor/Official Dub: Supporting characters announced!/@comment-1271618-20100707215727

Yao is China's given name, Wang is the surname. One problem with the human names here is the question of whether to list the Asian names in Eastern order (which we have) or in Western like everyone else's (which we did for staff).

Korea's surname is Im, his given name is Yong Soo (or Yongsoo, Yong-soo, any sort of variant of that). And Japan...well, yeah XD

I checked the Amazon article, it didn't really list any characters for the VAs. But we do know the director for the dub now, and they've worked on One Piece, My Bride is a Mermaid, and...Strike Witches!
