Meng's Dec. 1, 2018 arrest at Vancouver's airport was followed by China's seizing of two Canadians nine days later and charging them with espionage-related offences.

Crown prosecutors said an extradition hearing is not a trial and accused Meng's lawyers of trying to introduce evidence that would be more appropriate for a U.S. jury to hear.

If Ottawa does announce a formal ban on Huawei, the affected telecommunications companies have made clear they want compensation for tearing out their existing Huawei gear, said two sources close to the matter.

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.
