President Trump today announced that he was signing an executive order to ban U.S. companies from using foreign companies that might pose a threat to U.S. national security.

From the BBC…

The president signed an executive order which effectively bars US companies from using foreign telecoms believed to pose a security risk to the country.

Mr Trump does not name any company specifically in the order.

However, analysts suggest it is mainly directed at Chinese telecommunications giant Huawei.

A number of countries – including the US – have raised concerns that the company’s products could be used by China for surveillance. Huawei has said its work does not pose any threat.
