Take the US for instance. For the past several years, based on its claim that freedom of the Internet is a universal right, it has been trying to promote cyberspace as a public domain together with the Antarctica, the oceans and space, and has thus been avoiding the issue of national sovereignty.

The US' efforts reek of hegemonic philosophy. In fact, the US has been spreading its ideology in other countries through many websites and social networks, so as to trigger political disputes in societies that adhere to political philosophies other than that propounded by Washington. We should not forget that countries like Libya have become victims of the US' promotion of Western-style democracy.

Another reason for the US to talk about freedom of the Internet is to serve its trade and protectionist policies and cause trade frictions with other countries. With its modern technologies and global influence, Washington has been trying to help US-based enterprises enter other countries' markets on the pretext of defending free trade. When Google was pulled up by the Chinese government for violating the country's laws, the US government ironically accused China of not being a "free" country.

As a result, politicization of Internet freedom has become an obstacle to international cooperation. With the dispute over Internet freedom already a major international issue, countries with different understandings of cyberspace accuse each other of violating rules. Some of these differences have even led to trade frictions and protectionist measures.

Worse, other political issues are involved in the disputes over Internet freedom, which can easily turn into wider conflicts and make it more difficult for the related countries to resolve the existing issues.

Therefore, to boost global cooperation countries across the world should avoid pointing the finger against each other to prove whose Internet rules are better.
