>China also had made industry espionage their way to go in these things.
Few layman know this but France is one of the biggest industrial espionage players active in the US and Europe, after Israel of course.
In fact, according to Wikileaks diplomatic cables from Berlin quote: "France is the country that conducts the most industrial espionage [in Europe], even more than China or Russia."
Basically, every nation on the planet engages in espionage for its own benefit if they can get away with it. There's no honor amongst thieves.
Singling out China as if they're the only ones doing it, or the ones doing it the most, is both naive and hilarious.
Diplomatic cables are not a source of truth, they are heavily biased. The fact they had to be stolen does not give them more weight. There is a lot of bias in US governmental opinion on french technology that such a small country cannot be so advanced without stealing; opinion which started with the french nuclear and space program. My opinion on those discourses about France, China or the USSR in the past are just mostly propaganda from the US MIC to ensure continued funding.
