Bloomberg reported last year that in 2018 China is going to ban all VPN services in order to prohibit netizens access outside network.
It is said that the ban is already in effect, which happened in March, this year.
From news sources, it is said the government has already banned all unauthorized VPN services. If, this is true, netizens would have much trouble connecting to the outside world.
But I haven’t experienced any trouble connecting to my VPN service, but it might be the case that my VPN is the most efficient and the priciest you can find in China.
