WASHINGTON, Oct 28 (Reuters) - The Federal

Communications Commission on Wednesday voted to tighten

restrictions on telecommunications equipment made by Chinese

companies deemed national security risks, the latest in a series

of U.S. actions targeting Beijing.

The U.S. telecom regulator previously named companies

including Huawei, ZTE (Shenzhen:000063), China Mobile and

China Telecom to the so-called "Covered List," which

bars the FCC from authorizing the import or sale of new

equipment from those companies. The FCC voted 3-0 to prohibit

authorization of devices containing component parts from

companies on the list and authorize the agency to prohibit the

sale of previously authorized Covered List equipment in specific

cases.
