I bet neither China, nor Russia, nor the US would allow foreign citizens in foreign countries develop any serious military technology for their armies. Even their own citizens would be checked in detail before being allowed to work on it.

If a technology is not under that kind of scrutiny, chances are its military applications are... far-fetched.

Lots of military technology is traded between countries all the time, tanks, planes, guns, boats, missiles, etc. China just bought a bunch of Su35 jet fighters from Russia.
