The Czech Republic's national cybersecurity agency has urged against using software and hardware from Huawei and ZTE because they present a security threat.
Huawei and ZTE face new barriers to supplying equipment to critical infrastructure providers and government agencies in the Czech Republic.
The Czech security agency is the latest security body to raise an alarm over Huawei's technology and its potential to be used by Beijing for spying.
Following a US ban on government purchases of Huawei equipment, Japan earlier this month reportedly banned its government agencies from buying Huawei and ZTE equipment. Australia and New Zealand have barred Huawei and ZTE from supplying their respective 5G networks, both countries citing national security concerns.
While the Czech government has not banned Huawei and ZTE equipment, the formal security warning from Czech's National Cyber and Information Security Agency (NCISA) does have implications for some contracts in the country.
