Can Chinese companies order just the blades from RR or P&W?

I've watched their manufacturing video recently and shocked how much of it was hand labour - it's not something I'd associate with precision. My partner said they must know better tho lol.

The RR video showing manual assembly of wax molds is a low volume development line. It isn't their main production process.

I've seen that video. Guaranteed they wouldn't have put the slightest bit of information in there if they thought would help the competition.

They can order engines from RR or P&W

But those companies have no commercial interest in supporting a Chinese manufacturer that just wants the blades even without export controls, when they can make much higher margins selling whole engines that must be maintained using their parts (in practice variants of the engines destined for COMAC also omit some of the IP that finds its way onto Airbus and Boeing because you can help a customer too much...)
