Remember that China is the electronics manufacturing hub of the world. A lot of Chinese component manufacturers don't care that much if people outside China can use their products, because by far their biggest market is within China. Chinese companies aren't going to take the time to translate their datasheets just so a few hobbyists can play around with their chips. And if a company in the US really wants to use that chip, they'll probably just hire someone who speaks Chinese to read the datasheet. There are plenty of Chinese speakers around.
