A Canadian judge has rejected a request from Huawei's chief financial officer Meng Wanzhou, who wanted testimony from employees of the Chinese telecom giant to be admitted as evidence in her fight against extradition to the United States.

Axar.az reorts that Meng - whose father is Huawei founder and CEO Ren Zhengfei -- has been in a two-year battle against extradition over charges the firm violated US sanctions on Iran.

She is accused of defrauding HSBC by falsely misrepresenting links between Huawei and its Skycom subsidiary, putting the bank at risk of violating sanctions against Tehran as it continued to clear US dollar transactions for Huawei.

Lawyers for Meng, 49, believe the affidavits could show the banking giant was aware of the links between Huawei and Skycom, which sold telecom equipment to Iran.

The evidence would help demonstrate the prosecution case was "manifestly unreliable," according to the lawyers.
