US telecom equipment certifiers must now prove they are not controlled by banned entities

The US communications regulator is tightening rules for companies that test and approve telecom equipment. These labs must now prove they are not owned or controlled by entities the US has banned.

The US wants to ensure that the phones and other devices sold in the country are not secretly compromised. This rule makes it harder for certain foreign governments to influence the testing and approval process for these devices. It closes a potential backdoor for supply chain interference.
