My recent work, “The Khitais and Jurchens as Seen from the Korean Peninsula”(Kyoto University Press, 2010), is a book that looks at the history, languages, and scripts of the Khitais in the Liao Era, the Jurchens in the Jin Era, and the Manchus in the Qing Era over a thousand years from the viewpoint of the Korean Peninsula. If you are interested in Asian-Pacific history, I recommend that you read it.
