Huawei CFO Meng Wanzhou, 46, who is also the daughter of the company founder, was arrested on Dec. 1 at the request of the United States.
The arrest, revealed by Canadian authorities late on Wednesday, was part of a U.S. investigation into an alleged scheme to use the global banking system to evade U.S. sanctions against Iran. The news roiled global stock markets on fears the move could escalate a trade war between the United States and China after a truce was agreed on Saturday between President Donald Trump and Xi Jinping in Argentina.
Trump did not know about the arrest in advance, two U.S. officials said on Thursday, in an apparent attempt to stop the incident from impeding talks to resolve the trade dispute.
Details of the case against Meng, to be heard in the Supreme Court of British Columbia, remain sparse.
