The integrated encryption might be interesting.  Perhaps another objective is to better defend Chinese users and critical infrastructure against cyber attacks (including retaliatory attacks), especially since use of that technology could be mandated and would gradually become universal there.

Of course mandated use of a single processor architecture, no matter how good, would carry its own risks...
