US President Donald Trump signed an executive order Wednesday that allows the US to ban telecommunications equipment and services from foreign companies that could pose a threat to national security, making good on a threat that escalates the battle against Chinese telecom giant Huawei.

The order doesn’t list any countries or companies by name but it instructs the Commerce Secretary, Wilbur Ross, to ban transactions “posing an unacceptable risk,” which include import of gear or services from companies that have close ties to foreign governments and could use their equipment to monitor or disrupt US telecommunications or other infrastructure.

In addition to the executive order, the Commerce Department said on Wednesday that it had placed the Huawei and 70 of its affiliates on a list of firms that are deemed a risk to national security. Companies on the so-called Entity List would not be allowed to buy American components and technologies without US government approval.
