As far as I have been able to figure out and remember from my time in China...
Businesses are technically allowed to have VPNs. China still relies on foreign companies and a lot of Chinese companies rely on for example adwords to promote their business outside of CN.
(this doesn't mean it's uncommon for CN to try to hack into these VPN tunnels, but the goal is not blocking access, and more about corporate espionage).
The Great Firewall also operates on a (customer) ISP level (rules and DPI varies per ISP and city) and not so much on outgoing traffic.
Most western companies rent fiber directly that is not affected by the GFW.
For example I know they could easily spot OpenVPN traffic and send RST packets to the host (also any DNS request with vpn is often send to a honeypot). IPsec had better chances of success (perhaps because that was less common?).
The VPN (and information control) targets mostly local Chinese. They don't care too much about tourists (collateral damage).

- TorKlingberg 9y agoYou data is routed as phone network data to your U.S. carrier, who has the gateway to the internet. This is because mobile data protocols were originally not designed with the Internet in mind, but as a separate network. The internet gateways were added on later.
- ethbro 9y agoIf the only way to get a VPN license is to have it attached to a business license, then control over entities with a VPN is a lot easier. What they're presumably trying to prevent is anonymous VPNs (in that the client is unknown).
