China's firewall cannot stem the flow of internet: Twitter's co-founder

Censorship firewalls in countries that seek to undermine the free flow of information over the Inter

Twitter co-founder Evan Williams added it was hard to say how long these firewalls will be able to hold up the internet.

Currently, the Chinese government filters online content available on the Internet through what is called the "Great Firewall of China." The censorship is ostensibly meant to bar access to sites that promote pornography or violence and offer the kind of information that is deemed harmful for the Chinese citizens.

"We are just realising the promise of the internet. It is about democratisation of information that anybody can share with the world. It will continue to change institutions for the coming decades," Williams said.

Google has recently said it will leave China if the country continues to censor its web searches.
