Wanzhou, the daughter of the technology giant's founder Ren Zhengfei, faces extradition to the USA on suspicion that the executive violated US sanctions targeting Iran.
She is being sought for extradition by the United States, he said. "The company has been provided very little information regarding the charges and is not aware of any wrongdoing by Ms. Meng", he said.
The Globe and Mail reports that US law enforcement agencies allege Ms. Meng tried to evade USA trade embargoes against Iran.
Meng is the deputy chair of Huawei's board and is the daughter of company founder Zhengfei Ren, from his first marriage.
