The government of China has announced that only specific VPN software are allowed to be used by the civilians of China.
Via a VPN it is possible to hide your outgoing IP address by using another server that is provided by a third-party.
For example, you can use a VPN to visit censored websites like news sites, but it also allows the user to navigate the web without having to worry that logs are being kept (beware, only a couple of VPN providers do not keep logs).
Companies have not gained any information regarding to the new VPN regulation in China, so it is not clear if companies that use their own VPN will result in being fined or banned.
Apple already decided to remove any VPN application on their Chinese Application store.
It is not yet clear in what extence the new regulation will be enforced.
