New Delhi, Oct 27 (TIWN) Washington has revoked the US licence of one of China's biggest telecoms companies citing "national security" concerns, BBC reported.

This in turn could allow it "to engage in espionage and other harmful activities against the US", they said.  China Telecom, which has provided telecoms services in the US for nearly 20 years, called the decision "disappointing".  "We plan to pursue all available options while continuing to serve our customers," a statement said.  China Telecom is one of three companies that dominate China's telecoms market. The firm has hundreds of millions of customers in 110 countries, with services ranging from broadband internet to mobile and landline telephone networks.  The Federal Communication Commission (FCC) warned it might shut down China Telecom Americas in April 2020, claiming the firm "is subject to exploitation, influence, and control by the Chinese government".  It said the company was "highly likely to be forced to comply with Chinese government requests without... independent judicial oversight", the report said.  It is the latest Chinese telecoms firm to be targeted by US officials over national security concerns.
