Material sciences needed for modern jet engine blades are a closely guarded secret, and thanks to not manufacturing them in china, those secrets have managed to remain not stolen.

Fun story: it is not just jet engines - it is only recently that china was able to actually make indigenous ballpoint pens https://www.bbc.com/news/business-38566114

		yes, compared to the length of time ballpoint pens have existed (88 years -- since 1938), this is very recent - only 9 years ago

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.
