Donald Trump says he could intervene in the case of Huawei executive Meng Wanzhou if it helps to avoid a further decline in US relations with China.
“Whatever’s good for this country, I would do,” the US president said.
Ms Meng, the chief financial officer of the Chinese telecoms giant, was granted bail on Tuesday by a Canadian court.
She was arrested on 1 December and could be extradited to the US to face fraud charges linked to the alleged violation of sanctions on Iran.
Ms Meng, 46, denies any wrongdoing and has said she will contest the allegations.
She is the daughter of Huawei’s founder and her detention, which comes amid an increasingly acrimonious trade dispute between Washington and Beijing, has angered China and soured its relations with both Canada and the US.
In an interview with Reuters news agency on Tuesday, Mr Trump said he would intervene in the US Justice Department’s case against Ms Meng if it would serve national security interests or help achieve a trade deal with China.
“If I think it’s good for what will be certainly the largest trade deal ever made – which is a very important thing – what’s good for national security, I would certainly intervene if I thought it was necessary,” he said.
What happened in the courtroom?
Justice William Ehrcke in Vancouver set bail for Ms Meng at C$10m (£6m; $7.4m).
Of that, C$7m must be provided in cash with C$3m in collateral.
The judge said that she would be under surveillance 24 hours a day and must wear an electronic ankle tag. She will be unable to go out between 2300 and 0600 and must surrender all passports and travel documents.
In the three-day bail hearing in Vancouver, Ms Meng’s lawyers sought to provide guarantees that she would not pose a flight risk if released. The application was opposed by Canadian prosecutors.
