Huawei executive Meng Wanzhou, who was arrested in Canada and faces possible extradition to the United States, is exploring a defence that claims US charges against her are politically motivated, the Globe and Mail newspaper reported on Monday.
Meng, the chief financial officer of China's Huawei Technologies, is the central figure in a high-stakes dispute between the United States and China. Canada arrested Meng in December at the request of the United States and last month she was charged with wire fraud that violated US sanctions on Iran.
"The political overlay of this case is remarkable," Richard Peck, lead counsel for Meng, told the Toronto newspaper in a telephone interview.
"That's probably the one thing that sets it apart from any other extradition case I've ever seen. It's got this cloud of politicization hanging over it," Peck added.
The office of Canadian Justice Minister David Lametti said it could not speculate on Meng's possible defences.
"We are committed to a fair process unfolding before the courts and the steps undertaken by the Department of Justice Canada on this case have followed due process, in accordance with the Extradition Act, the Charter of Rights and Freedoms and our Treaty with the United States," a spokeswoman for Canada's Department of Justice said in an e-mailed statement.
Peck's office did not respond to a request for comment. A Huawei spokesman declined comment.
In December, US President Donald Trump said in a Reuters interview he would intervene in the Justice Department's case against Meng if it would serve national security interests or help close a trade deal with China.
Canada fired John McCallum, its ambassador to China, in January after he said Meng could make a strong argument against being sent to the United States.
"He [Mr McCallum] mentions some of the potential defences - and certainly, I think any person that knows this area would see the potential for those defences arising," Peck told the Globe and Mail.
Meng's lawyers are also planning to challenge whether her alleged conduct would be deemed criminal under Canadian law, the Globe and Mail said.
