Meng Wanzhou Huawei Technologies' CFO and daughter of the company's founder, was arrested in Canada and faces extradition to the US on reported accusations of violating US sanctions against Iran.
Huawei is the world's number two smartphone maker but also the world's top maker of telecoms equipment. Last week our government's electronic spy agency rejected Spark's bid to use Huawei technology for the new 5G cellphone network, citing significant national security risks.
China says it resolutely opposes the arrest of Meng Wanzhou, and is calling for her release.
