While walking the Great Wall of China is on almost every bucket list, China's building a new not-so-great wall in the digital world. China's digital firewall isn't built to keep invaders out, however. It's designed to lock Chinese Internet users in.
And now, it's getting bigger.
The cost of building China's massive firewall is information. Every Internet tool released in China needs to be adapted into China's firewall. This means that the Chinese government knows a lot about any application or tool released within its digital borders.
Authorities suspect that this firewall might arm China with powerful cyberweapons.
