That might be hard.If i recall correctly a few years ago there were some numbers indicating somewhere between 1-3 million people who were either "proper spying", doing espionage(industrial,research,etc) or having ties(actively involved, not merely having relatives/distant connections) with China living in the US.[I will edit with a source assuming it still is online, otherwise i have to dig in my local data] This happens a lot at 'FAANG-tier' companies, but then again screening employees is virtually impossible at this scale, US companies still have an advantage and they remain ahead of the competition because copying/leaking information takes time, and the re-engineering also takes time.Academia is a sensitive area, because on one hand you have to be transparent and keep discourse public and open, but on the other hand state-sponsored entities actively engage in battles(especially cybernetic ones) to control narratives about certain subjects, especially in 'public spaces'.
