Meng Wanzhou, chief financial officer of China’s Huawei Technologies, was detained by Canadian police in Vancouver for possible extradition to the US. Beijing has demanded her immediate release. Meng, who is also the daughter of the company founder Ren Zhengfei, has a bail hearing on Friday. A publication ban is imposed on the case by the Canadian authorities. Earlier this year, the WSJ reported that US authorities are investigating the Chinese tech giant for possible violations of sanctions on Iran.
