The financial director of Huawei Communications Technologies, Meng and Enzo, was arrested in Canada at the request of the US authorities on 1 December, according to Ian McCloud, spokesman for the Ministry of Justice.
Wanzo faces the prospect of being deported to the United States and representatives of the company can not be reached for further information.
Anzo, the daughter of the founder of Huawei, has asked for a ban on the publication of all information and a court order, according to McCloud.
Huawei plans to roll out a smartphone with a folding screen in a year. The dispute between Samsung and Huawei over patent infringement continues. US media also reported that the United States was investigating possible violations by Huawei of US sanctions against Iran.
US lawmakers have repeatedly accused the company of threatening US national security, saying that the technology it uses can be used for espionage by the Chinese government.
Earlier this year, US companies were unable to export to the Chinese telecommunications company ZT due to violations of Iranian sanctions, effectively blocking the company. The United States later changed their decision to replace the ban.
Meanwhile, China urged Canada and the United States to clarify the reasons for the arrest of Wanzo and to request immediate release.
Wanzo was sitting in court in Vancouver on Friday to see her release on bail while waiting for her to be deported to the United States.
Sources familiar with the investigation said Reuters that its detention, announced by the Canadian authorities on Wednesday night, was part of an American investigation into allegations of planning to use the global banking system to circumvent US sanctions against Iran.
The arrest of the Chinese executive led to the turmoil of global equity markets, fearing this would escalate the Sino-US trade war after a ceasefire agreed on Saturday by President Xi Jinping and his US counterpart Donald Trump in Argentina.
US officials said Thursday that Trump had not been informed in advance. The statement seemed to prevent attempts to stumble over discussions about resolving the trade dispute on the subject. There are still few details in the case before the Supreme Court of the British Columbia District.
The Canadian Department of Justice refused to give details of the case and Meng obtained a decision to ban publishing, thereby limiting the ability of the media to restrict the evidence or documents presented in court.
Huawei, with an estimated 1,000 employees in Canada, has been extensively reviewed in many Western countries because of its relationship with the Chinese government. This is due to the fear that Beijing uses it for espionage.
Reuters said in April that the United States has also been considering, since at least 2016, whether Huawei has violated US sanctions against Iran.
