China warned Canada on Saturday that there would be severe consequences if it did not immediately release Huawei Technologies Co. Ltd's chief financial officer, calling the case "extremely nasty."
Meng Wanzhou, Huawei's global chief financial officer, was arrested in Canada on Dec. 1 and faces extradition to the United States, which alleges that she covered up her company's links to a firm that tried to sell equipment to Iran despite sanctions.
The executive is the daughter of the founder of Huawei.
