Yesterday at DL a Korean visitor chanted the Gospel text in Korean (part of the recitation of that text in different languages as a part of the celebration of Pascha) - the chant sounded familiar, but I can't say if it is exactly the same as what I heard at the local Korean Catholic church a while back. I should visit that parish again some time, and find out if one of the Korean-American priests in the diocese knows something about it. Alas, Chinese is a family of tonal languages, but maybe there is something to adapting Buddhist chant to Christianity.
