The US has requested the extradition of Huawei CFO Meng Wanzhou from Canada.

Meng was arrested in Canada on December 1, and her case has rocked Canadian politics as well as relations with China, which has claimed the arrest was politically engineered by the US.

The US indicted Meng and Huawei on Monday, accusing the tech giant of flouting US sanctions and stealing trade secrets from T-Mobile.

Meng and Huawei deny any wrongdoing.

The US has officially requested the extradition of Huawei CFO Meng Wanzhou from Canada, The Wall Street Journal reports.

Canada said it received the extradition request on Tuesday, according to The Journal, a day before the deadline for the US to submit the request. Meng was arrested during a stopover in Vancouver, British Columbia, on December 1 on suspicion of breaking US trade sanctions.

On Monday, the US indicted Meng and Huawei, accusing the tech giant of circumventing US sanctions on Iran and stealing trade secrets from T-Mobile. Sen. Mark Warner called the company a “national security threat,” believing the company to be acting as a backdoor for the Chinese government.

Meng and Huawei have denied any wrongdoing.

China has repeatedly decried the move as politically engineered by the US. The Journal reports that Canadian officials have until March 1 to review the request.

The question of Meng’s extradition has sent ripples through Canadian politics. Prime Minister Justin Trudeau on Saturday fired Canada’s ambassador to China, John McCallum, after he said the US dropping its plans to lodge an extradition request would be “great for Canada.”

Meng’s arrest also prompted retaliation from China, which subsequently detained two Canadian citizens and put another on death row.

A Huawei spokeswoman issued the following statement to Business Insider:

“Huawei is disappointed to learn of the charges brought against the company. After Ms Meng’s arrest, the Company sought an opportunity to discuss the Eastern District of New York investigation with the Justice Department, but the request was rejected without explanation. The allegations in the Western District of Washington trade secret indictment were already the subject of a civil suit that was settled by the parties after a Seattle jury found neither damages nor willful and malicious conduct on the trade secret claim.”

“The Company denies that it or its subsidiary or affiliate have committed any of the asserted violations of US law set forth in each of the indictments, is not aware of any wrongdoing by Ms Meng, and believes the US courts will ultimately reach the same conclusion.”
