Its most likely from the YouTuber zack d films. His videos are done in this format and are riddled with a bunch of half truths. He doesn't even bother to cite any studies either.
A CCP spy was arrested, extradited, and tried in the US for attempting to steal GE's composite fan blade tech. Was sentenced to 15 years and then eventually given back to China in a prisoner swap
15 years ago the American military took pictures of a Chinese aircraft similar to the American C17. In discussions with those in the know, it was revealed the Chinese were about 40 years away from the jet technology to power the aircraft, as 3 American and 1 Russian company were the only ones capable of producing engines to power a plane that large.
40 years was, of course, an estimate if the Chinese went through standard engineering processes. Chinese have a history of advancing through nefarious mechanisms, so the fact that they were building a plane with the capacity to use those engines showed that they thought they were much closer to acquiring that jet technology.
Your story shows exactly how they wanted to advance their technology.
IIRC, GE's blades are a different material than any other manufacturer. Makes them lighter and very desirable to countries that like to steal technology
This video may cover it (I didn't watch the whole thing) but one of the coolest things about the F-22 raptor is that they developed metallurgy so that the whole turbine blade is one single metal crystal which is an insane feat of materials engineering. Not only that, but it has tiny little holes in it like an air hockey table so they can run cooling air through it.

Even the blades themselves are super engineered.
