Google sees censorship as trade barrier

Google offers an interesting twist in the censorship dilemma, as it asked US trade officials to treat internet censorship as an international trade barrier, writes AP. Not only it the proposal interesting, it also seems that Google is now actively engaging into governmental relationships, a field it would try to avoid in the past.
This is the argument:

Google sees the dramatic increase in government Net censorship, particularly in Asia and the Middle East, as a potential threat to its advertising-driven business model, and wants government officials to consider the issue in economic, rather than just political, terms.
