On Capitol Hill, the bills introduced by Senator Tom Cotton and Representative Mike Gallagher, both Republicans, along with Senator Chris Van Hollen and Representative Ruben Gallego, both Democrats, specifically cite Huawei and ZTE, both of which are viewed with suspicion in the United States because of fears that their switches and other gear could be used to spy on U.S. citizens.
Huawei denies ties to the Chinese government, and its equipment is widely used in Canada's telecom networks: Bell and Telus partnered with Huawei to test 5G technology, although the federal government has considered banning the company from access to the network.
Republican Carrego said: "Huawei and ZTE have systematically undermined the security of the United States and the cybersecurity network". Other so-called Five Eyes countries including the USA and Australia have placed restrictions on Huawei's operations given its close ties to the Chinese government, moves that place pressure on Canada to make a decision.
Handelsblatt, citing government sources, said government officials were discussing setting security standards that Huawei could not achieve, effectively blocking its participation.
The shift by the national market leaders, both partly state owned, followed Huawei's exclusion on national security grounds by some USA allies, led by Australia, from building their fifth-generation (5G) mobile networks.
Canada has said little about the review into 5G technology.
The 5G security review is drawing heightened interest amid a rising diplomatic feud sparked by Canada's arrest - at the request of the us - of Huawei's Chief Financial Officer Meng Wanzhou on December 1.

Mnangagwa is yet to meet Putin to explore new opportunities for cooperation between the two countries. Mnangagwa also announced that foreigners will have to pay in foreign exchange for their fuel.
Two Canadians have been detained in China since Meng's arrest and a third has been sentenced to death on drug trafficking charges - moves observers have seen as attempts by Beijing to pressure Ottawa over her case. "We hope Canada thinks twice before making any actions", said Lu.
"Huawei has stolen that technology".
The Chinese government retaliated against the arrest by detaining Michael Kovrig, a former Canadian diplomat, about a month ago, claiming he's a national security risk.
In response, Freeland said Canada had no intention of changing its approach.
He also warned Prime Minister Justin Trudeau to back off from his efforts to recruit additional global support in Canada's feud with China. There are accusations that Huawei, the world's biggest maker of telecom network gear, is controlled by China's ruling Communist Party or is required to facilitate Chinese spying.
"Oxford University decided on January 8 this year that it will not pursue new funding opportunities with Huawei Technologies Co Ltd or its related group companies at present", an Oxford University spokesman said in a statement.
