Jade-blooded I think, are only mentioned in a cut piece of a WFRP book that was later published on the writer's website.

I can't think of any BL books that have them mentioned, though we have had Vampires that did live in the far east appear in some books, those were Von Carstein's pic as an example.
The only official source so far is TWW, which references them with items and a Special Building in Cathay.
