WASHINGTON, April 9 (Reuters) - The U.S. Federal

Communications Commission said it may bar three major Chinese

telecom companies from operating data centers in the United

States and ban other carriers from connecting with them in the

United States.

The FCC said it has tentatively concluded it should prohibit

American and other telecommunications carriers operating in the

United States interconnecting with companies on the so-called

"Covered List" that it says pose national security concerns,

including China Mobile, China Telecom

and China Unicom.
