No, not to my knowledge. All the Chinese cards are mentioned in the excellent articles made by @guangsta.

I’m pretty sure they just used the exact same numbering as the English cards they’ve copied from. Some of them are from POP1, others POP2, some POP4, and some promos. All have a.f.a.i.k. the same numbering as the English counterparts with the same artworks.
I don’t know if there are 10 or 17, though. But I’ve only seen those pictured in the articles myself.
And no, I’m not the high end Pikachu collector who bought the first copy. That would be Justin, who posted about it here on E4 in his collection thread. Although I haven’t spoken to Justin in a long while, he isn’t very actively collecting Pikachus anymore since he moved and I surpassed him near the end of 2017, and his website is also missing quite a few of the newest releases (although it does contain most Sun & Moon cards). In terms of total amount, I currently have the largest Pikachu collection, Tom from Belgium second, and Justin third (a.f.a.i.k.). I have quite a few errors, though. So excluding those, only looking at officially released Pikachus, Tom currently has more than me (about 20 more). Not that numbers really matters, we all three are collectors who just love to collect all Pikachus. 
I’m not sure what his source was, but Tom was able to buy three of these Chinese POP4 Pikachus at the start of this year, and he sold one of those three to me (and the third is also already gone). So all three of us are in the possession of the Chinese POP4 Pikachu, and have all four available Chinese Pikachus in our collection (the other three being Base 1st ed.; Base UED; Jungle PWC2000 tail-stamped).
