This is about research and papers published - but Chinese academia is amongst the most corrupt in the world, so without the technologies being utilised (or at least peer reviewed by more trustworthy people) this really doesn't mean all that much.
Honestly, if the Chinese were that far ahead they wouldn't depend on industrial espionage to the extent that they do.
Nature runs an index of how many papers are published in top journals by scientists in each country and institution: https://www.nature.com/nature-index/country-outputs/generate.... Chinese scientists publish more papers in leading international journals than scientists from any other country, including the US (though it's neck and neck at the moment).
You haven't addressed the point I made above, which is that Chinese scientists are now consistently getting published in the most prestigious international journals, in numbers exceeding even US scientists.
Honestly, if the Gringos were that far ahead they wouldn't depend on industrial espionage to the extent that they do.
I feel threatened by an ethnosupremacist regime that would murder tens of millions of its own citizens.
Crazy huh?
