The daughter of Huawei’s founder, a top executive at the Chinese technology giant, was arrested in Canada and faces extradition to the United States, stirring up fears it could reignite a Sino-U.S. trade row and roiling global stock markets, Reuters reported.

The arrest of Meng Wanzhou, 46, who is Huawei Technologies Co Ltd’s chief financial officer, threatens to drive a wedge between the United States and China just days after they agreed a 90-day trade war truce in Argentina on Saturday - the day she was detained.

Meng’s arrest, revealed late on Wednesday by Canadian authorities, is related to U.S. sanctions, a person familiar with the matter said. Reuters was unable to determine the precise nature of the possible violations.
