Indeed. The Chinese measures seem geared mostly towards stopping people (connection resets, dns poisoning, etc), whereas the US ones towards criminalizing people (logs.) Which is not to say that the Chinese would never prosecute you as a criminal, they probably will if it suits them, but it's not their default modus operandi.
Perhaps it's because when some governments go after their citizens they don't bother with niceties like 'evidence', 'logs' or even 'trials'.
