Given that I've recently had some issues with failures & warranty on high-end Chiner parts, and getting burned by aliexpress dealers, I definitely see a market for PP helping facilitate high-end sales. There's a lot of brands selling stuff that rivals elite-tier western-market parts (Cybrei, Seka, Magene, Farsports, Craft, EXS) but at that point you are reaching deep into the pockets.
In the past (for me any way), the psychology driving my strategy for buying Chiner parts was that perceived risk of getting a dud part was high, so the price needed to be cheap enough to mitigate loss aversion. But this mentality caps how much you're willing to spend on parts, and in turn, limits maximum quality that is marketable.
If you can have some assurances that the dealer will have integrity/good service, and will work with you on warranty issues, then you're going to increase how much money people are willing put on the line.
