The House on Wednesday unanimously passed a Senate resolution introduced by Sens. Claire McCaskill (D-Mo.) and Marco Rubio (R-Fla.) that calls on the U.S. government to oppose United Nations control of the Internet.

The 397-0 vote is meant to send a signal to countries meeting at a U.N. conference on telecommunications this week. Participants are meeting to update an international telecom treaty, but critics warn that many countries’ proposals could allow U.N. regulation of the Internet.

“The 193 member countries of the United Nations are gathered to consider whether to apply to the Internet a regulatory regime that the International Telecommunications Union created in the 1980s for old-fashioned telephone service,” Rep. Greg Walden (R-Ore.) said on the House floor.
