Meng Wanzhou, the detained CFO of Huawei, is seeking bail in Canada on concerns for her health.
However, Canadian prosecutors have argued she can't be trusted.
Meng is fighting to be released after her arrest earlier this month in Vancouver.
She faces extradition to the United States.
Court documents showed U.S. authorities accuse her of misleading banks and putting those banks at risk of breaking U.S. sanctions on Iran.
They allege she was trying to use those banks to move money out of Iran.
Court documents also show that in the meantime, she wants to be released, and not only on grounds she suffers from hypertension.
She's also citing her longstanding ties with Canada and mentioned she owns two homes worth millions in Vancouver.
Prosecutors have argued against giving Meng bail.
She is also the daughter of the founder of Huawei, one of China's key tech companies.
It's the world's biggest supplier of networking hardware.
China has demanded Meng's immediate release.
(SOUNDBITE) (Mandarin) CHINESE FOREIGN MINISTRY SPOKESMAN GENG SHUANG, SAYING:
"Neither Canada nor the U.S. has provided China any evidence that Meng has broken any law in those two countries."
Meng's arrest has put global markets on edge with investors worried it could sabotage any chance of a trade deal between Washington and Beijing.
On Sunday (December 9), China's foreign ministry summoned the U.S. ambassador to lodge a 'strong protest' over the arrest, and to tell the U.S. to withdraw the warrant.
In a sworn affadavit, Meng said she is innocent and will contest the allegations at trial in the U.S. if she is handed over from Canada.
Her family assured the court she would remain in Vancouver if she was granted bail.
Meng returns to court for a bail hearing Monday (December 10).
