The U.S. is banning the sale of communications equipment made by Chinese companies Huawei and ZTE and restricting the use of some China-made video surveillance systems, citing an “unacceptable risk” to national security, AP reports.

The five-member Federal Communications Commission said Friday it has voted unanimously to adopt new rules that will block the importation or sale of certain technology products that pose security risks to U.S. critical infrastructure.

It’s the latest in a years-long escalation of U.S. restrictions of Chinese technology that began with President Donald Trump and has continued under President Joe Biden’s administration.

“The FCC is committed to protecting our national security by ensuring that untrustworthy communications equipment is not authorized for use within our borders, and we are continuing that work here,” said FCC Chairwoman Jessica Rosenworcel, a Democrat, in a prepared statement.Along with Huawei and ZTE, the order affects products made by companies such as Hikvision and Dahua, makers of widely used video surveillance cameras.
