On 1 December the CFO of Huawei is arrested in Vancouver, Canada, based on an extradition request from the US Government. Huawei is a world leader in developing new generation 5G mobile telecoms networks. US authorities are seeking the CFO’s extradition for alleged fraud, claiming that Meng Wanzhou lied to American banks about the relationship between Huawei and a company called Skycom in order to circumvent sanctions on Iran. US authorities claim that Skycom was an “unofficial subsidiary” of Huawei, run from 2009 to 2014 to violate sanctions. The Chinese telecoms equipment supplier is also under pressure in other Western countries as governments fear its technology can be used for spying. The CFO’s father Ren Zhengfei, founder and president of Huawei, denies that China’s new national security law obliges Huawei to build routes to gather electronic intelligence into its telecoms equipment.
