That has nothing to do with copyright laws in China. Plenty of fans develop games which infringe on copyrights in the West too. The difference is PvZ is very popular in China and they have a lot of talented coders. They were the ones who pioneered PvZ/PvZ2 hacking. The net result is a bunch of fan games based on PvZ coming from that side of the world.
