China
is another example of countries that impose strict rules regarding Internet accessibility.
Websites are blocked using a system called The Great Firewall of China. Also,
there is a system applied in Internet cafes and public places that offer free WiFi
service that enables police to track down and monitor Internet users' online
activity. Citizens who live in China have limited access to the Internet and
when they travel outside China they cannot access Chinese websites. All social
networks, blogging sites and even free e-mail hosting services are banned in
China. To open blocked sites in China, you need to use a strong VPN that
cannot be detected or disrupted by the Great Firewall of China.
