A representative for China said at the closed-door meeting on Friday that the measures "are clearly inconsistent with WTO rules, restrict cross-border trading services and violate the basic principles and objectives of the multilateral trading system," a trade official familiar with the matter, who did not wish to be identified, said.
The official said the delegate described the US failure to provide concrete evidence of the reasons for its measures a "clear abuse" of rules.
In the same meeting, the United States defended its actions, saying they are intended to mitigate national security risks, the trade official said. The government has previously said data from American users is being accessed by the Chinese government.
The office of the US Trade Representative had no immediate comment. An official at the Chinese mission to the WTO did not immediately respond to a request for comment.
