A high-flying Chinese executive has been caught in the centre of a growing geo-political dispute between two of the world's largest economies.
Meng Wanzhou is the chief financial officer of Huawei and the elder daughter of the telecom giant's founder.
She was arrested in Canada last week for allegedly breaking US sanctions on Iran and faces extradition to the US.
China and Huawei insist that she has not broken any laws but she could be jailed for up to 30 years if found guilty.
So who is she?
Ms Meng, also known as Sabrina Meng and Cathy Meng, has risen up the ranks of Huawei, China's largest private company.
The 46-year-old started her career as a receptionist in 1993, and after graduating with a master's degree in accountancy from the Huazhong University of Science and Technology in 1999, she joined Huawei's finance department.
The US has been investigating the world's largest smartphone maker since 2016, which it believes used a subsidiary to bring US manufacturing equipment and millions of dollars in transactions to Iran.
Ms Meng's arrest has now sparked an escalating diplomatic incident between China, Canada and the US.
Life revealed in court
In documents filed in the Supreme Court of British Columbia, where Ms Meng's case is being heard, details have emerged revealing the CFO's personal life.
She is a thyroid cancer survivor who suffers from hypertension and a sleep disorder, her lawyers said, in need of daily doses of medication.
"I continue to feel unwell and I am worried about my health deteriorating while I am incarcerated," she said in the filing. "I currently have difficulty eating solid foods and have had to modify my diet to address those issues."
Her lawyers are seeking bail for the mother of four, who, they say, is not a flight risk because of her "strong roots" in Vancouver.
She told the court she was a Canadian resident until 2009, after which she returned to China.
However, she bought a six-bedroom house with her second husband in the city and would return regularly to visit him and her children, some of whom attended Canadian schools until 2012.
That home is now reported to be worth C$5.6m (£3.3m, $4.2m), according to property records and an affidavit Ms Meng read out in court.
In 2016, the couple bought a second property, a mansion worth C$16.3m - both homes have been put up as collateral for bail.
The court papers give a fascinating insight into the life of a senior Chinese executive, says BBC World Service Asia-Pacific editor Michael Bristow.
"Vancouver has for some years been a destination of choice for wealthy Chinese people; as a place to live, educate their children, or as an insurance policy against the uncertainties of life back in China.
"People will be intrigued to find out Ms Meng has not one but two homes in Vancouver, and wonder at how she was able to hold seven passports at the same time."
How does she have seven passports?
This remains somewhat of a mystery.
According to media reports, the tech boss has at least four Chinese passports and three Hong Kong passports.
“In the past 11 years, Meng has been issued no fewer than seven different passports from both China and Hong Kong,” a letter from the US Department of Justice to Canada read, claiming she was a flight risk. It also listed the numbers of the seven passports.
