Google is against a forthcoming conference organised by the United Nations on the internet.
Government representatives are to discuss a new information and communications treaty from 3 - 14 December in Dubai.
The BBC reports Google has asked web users to add their name to an online petition to support its view that the event conference threatens the "free and open internet".
The company's website said:
"Some proposals could permit governments to censor legitimate speech - or even allow them to cut off internet access.
"Other proposals would require services like YouTube, Facebook, and Skype to pay new tolls in order to reach people across borders. This could limit access to information - particularly in emerging markets."
The International Telecommunication Union has said a new treaty is needed to ensure "the free flow of information around the world, promoting affordable and equitable access for all and laying the foundation for ongoing innovation and market growth".
It added that the growth of the internet and adoption of mobile phones meant the existing agreement, which was signed in 1998, needed to be updated.
