[bbc] China wants to meter all internet traffic that passes through its borders, it has emerged.
The move would require international agreement - but it is being discussed by the United Nations body in charge of internet standards.
It would allow countries which currently receive no payment for use of their lines to generate income.
But an EU cyber security expert has warned the plan could threaten the stability of the entire internet.
Andrea Servida, of the European Commission, told a House of Lords committee that China could have a "hidden agenda" in wanting to monitor data flows.
And, in later comments to BBC News, he suggested technical changes needed to charge everyone for internet traffic flowing through China could undermine the web's founding principle of openness as well as raising security and stability concerns for all net users.
