On Tuesday, Britain became the last of Canada's Five Eyes intelligence-sharing allies to ban the Chinese telecommunications firm from its 5G wireless internet.

U.K. Prime Minister Boris Johnson is set to ban Huawei from Britain's 5G network on Tuesday, angering China but delighting U.S. President Donald Trump.

The opposition Conservatives are pressing the Liberals to deny Huawei a role in assembling the country's 5G infrastructure, alleging it will allow Beijing to spy on Canadians more easily.

The estimate came in an annual New Year's message to employees from chairman Eric Xu. The letter predicted 2020 would be a difficult year, saying the American pressure creates a challenging environment for Huawei to survive and thrive.

Canada says their arrests were "arbitrary," and has been in a diplomatic dispute with China since then.

Two Canadians have been detained in China for one year in apparent retaliation for Meng's arrest.

Meng's defence says the case is really about the United States seeking to enforce its Iranian sanctions laws against her for conduct that took place outside both the United States and Canada.

Speaking at the Halifax International Security Forum, U.S. national security advisor Robert O'Brien likened Huawei's implementation into Canada's network as a "Trojan Horse," and called for the release of the two Canadians Michael Spavor and Michael Kovrig in China.

Border officers seized Meng's cellphones, tablet and other devices and wrote down her passcodes on a piece of paper that they handed to the RCMP when she was arrested.

Chinese tech giant Huawei said Monday its revenue rose 39 per cent over a year earlier in the latest quarter despite U.S. pressure on allies to shun its telecom technology as a security risk.
