Meng Wanzhou, chief financial officer of Chinese telecoms giant Huawei, is facing fraud charges relating to alleged sanctions-breaking dealings with Iran, a Canadian court has heard.
Details of the charges were revealed when a publication ban was lifted by a judge in Vancouver.
Ms Meng, daughter of Huwei’s founder, was arrested in the city on Saturday and faces extradition to the US.
The court is deciding whether or not to allow bail.
China has demanded Ms Meng’s release, insisting she has not violated any laws.
The arrest has put further strain on US-China relations. The two countries have been locked in trade disputes, although a 90-day truce had been agreed on Saturday – before news of the arrest came to light on Wednesday.
Huawei is one of the largest telecommunications equipment and services providers in the world, recently passing Apple to become the second-biggest smartphone maker after Samsung.
