Every government knows exactly what foreign parts they’re supplying to COMAC because all parts need to go through an export control check first. There’s already a record.Given the amount of Western sanctioning Chinese companies like COMAC have been faced with, I wouldn't be surprised the blurring/censoring restricts the exposure of the tech/parts used in the C919 to Western parties - you can't sanction someone when you don't know what to sanction.... or something along those lines anyway.
