End user access starts in a provincial/regional network, which is connected to a national "backbone", which maybe allows the traffic out of the country. In my experience there's massive packet loss between the province and "backbone". 40% loss is regular throughout the day. Stuff within China mostly works, but anything outside is flaky at best.
Now obviously enterprise can't put up with that crap, so there's better routes out. Say a datacenter in Guangdong province that has direct peering with Hong Kong where licensed companies are colocating. Those companies with access can take money, (or under the table their sysadmins can) to terminate a VPN or MPLS connection there, giving unfiltered access to the internet and bypassing the lossy path.
The going rate I've found for this is about USD $300 per megabit per month, plus whatever the costs are to get there. (eg. Your regular broadband connection if using a VPN or cost of MPLS/Lan extension type service from the telco) Too expensive for most individuals, but definitely worth it if you're a hotel catering to foreign guests who will be pissed off if Google, Facebook, and pretty much everything they recognize about the internet doesn't work.
In my view this document is calling for, among other things, rooting out of this kind of activity.
If anyone is familiar with this market for unfiltered internet in China I'd like to learn more about it.
