Re: Let me be the first:
'As I understand it only US companies and citizens who would need a license to "export" or "import" the information.'
No, it's for export. One can import any information without suffering from an ITAR violation prosecution and fines. Exporting the wrong thing can get quit costly.
Such as one firm that develops state of the art night vision for the US DoD and those blessed by the US government to receive those devices as well, who made the brilliant decision to order sensitive components from the PRC. That resulted in $150 million in fines and concessions from the company (free services to the government).
Meanwhile, I can legally import Russia's favorite nuclear weapons designs, the most that would happen is a very, very threatening NDA (which I had already signed back in the 1980's) against revealing the contents of the new born secret documents and the NRC would confiscate the plans.*
Of course, I have no access to such plans, nor would I desire to somehow access those plans. That is just an outrageous example.
*By law, *all* things nuclear, be they fissionables above a certain curie unit or nuclear weapons belong, by law, to the NRC. Back when the core had to be inserted to arm a nuclear warhead, the core had to be signed out from the then AEC and signed back into AEC storage.
Yeah, US laws can get *quite* interesting. Add in federal, state, county and municipal, things can be rather tangled unless you review the US and state Constitutions.
