I like how the China of the Fallout universe is basically a mix of all east asian countries and some SEA countries.
One thing I didn't know until after watching the video was that China was already trying to build its own power armor before the war even started. For whatever reason, they somehow managed to master stealth technology before the power armor and were at most left in prototype stages before the nukes dropped. Man, I hope in Fallout 5, they expand on all the Chinese tech/prototypes. They are some of the more interesting and fun things in the lore. This especially if for Fallout 5, we go back to South CA like in Fallout 2.
