Escape from ARC

I just notice Chinese, Japanese, Vietnamese, or Korean on holo-signs in one of the tunnels and I may have heard some in the background as the youtuber walked his Mantis through said tunnel on this map, in this video after 14:00: https://www.youtube.com/watch?v=d6W5OaavH98. Does this suggest that some of Alluvion's colonists are of Asian descent? - EpicZealot1239, 4:55:05 PM, July 9th, 2015.
