The resume of actress Wendy Mok has seen her provide voice work for the unannounced project as a 'Chinese Village / Zombie', according to The Silent Chief.
Asia is currently an unexplored territory for the long-running survival horror series, which has been set in North America, Europe and Africa.
It's the second time this week that Resident Evil 6 has appeared on a voice actor's resume.
Capcom first discussed Resident Evil 6 in early 2009, saying that it would "reinvent the series" to keep it fresh.
The publisher has said that Resident Evil 6 would focus more on horror following two action-driven iterations.
It was also recently rumoured for a Tokyo Game Show reveal, but failed to come to light.
