Huawei's rise to dominance has generated controversy.
Huawei has said it knows little of the charges and was "not aware of any wrongdoing by Ms Meng".
The exact circumstances of her arrest were unclear.
The Chinese embassy in Canada responded to news of Meng's arrest by lodging stern representations against the USA and Canadian governments and calling for her immediate release. Canuck officials were asked by the Americans to detain the CFO just a few days before she was ultimately nabbed in Vancouver.

Huawei is by far China's most global technology company, with operations spanning Africa, Europe and Asia.
Several other past and present Skycom directors appear to have connections to Huawei.
