Huawei said Friday a ban on the Chinese telecoms giant from Canada's 5G networks was "an unfortunate political decision" that cannot be justified on national security grounds raised by Ottawa.

"Huawei Canada is disappointed by the Canadian government's decision," the company's Canadian subsidiary said in an email to Agence France-Presse (AFP). "This is an unfortunate political decision that has nothing to do with cybersecurity or any of the technologies in question."

It said that Huawei hardware and software have been "routinely and closely scrutinized" by the Canadian government and its security agencies, and to date, there have been "zero security incidents caused by Huawei equipment."

Canadian Industry Minister Francois-Philippe Champagne made the announcement on Thursday, citing Ottawa's "intention to prohibit the inclusion of Huawei and ZTE products and services in Canada's telecommunication systems."

The move follows key allies who have outright banned or restricted Huawei.

The United States has warned of the security implications of giving Chinese tech companies access to telecommunications infrastructure that could be used for state espionage.

Both Huawei and Beijing have rejected the allegations, while Beijing warned of repercussions for nations placing restrictions on the telecoms equipment provider.

The U.S. also on Friday hailed Canada's decision to ban its 5G network from China's Huawei.

"We welcome Canada's decision. The United States supports efforts to ensure countries, companies and citizens can trust their wireless networks and their operators," a State Department spokesperson said.
