The chief financial officer’s lawyer said that at least two senior HSBC leaders were aware of the connection between Huawei and its Iranian subsidiary.

Lawyers opposed to the extradition of Huawei’s chief financial officer from Canada to the United States submitted internal e-mails from HSBC in the United Kingdom. They stated that they refuted the United States’ claims that Huawei misled the bank.

Chief Financial Officer Meng Wanzhou’s legal team said on Tuesday that emails and documents submitted to the Canadian court showed that at least two senior HSBC leaders were aware of the connection between Huawei and its Iranian subsidiary Skycom. HSBC declined to comment.

Meng’s lawyers are trying to add these documents to the evidence. They aimed to refute the US allegations that only junior employees of this British bank know the true nature of the relationship between Huawei and Skycom.

U.S. prosecutors accused Meng of misleading HSBC in Huawei’s business transactions in Iran and may cause the bank to violate U.S. sanctions.

She was accused of lying to HSBC about the relationship between Huawei and Skycom, which violated U.S. trade sanctions to conduct business in Iran. U.S. prosecutors claimed that she misled HSBC and made the bank criminally liable for violating sanctions.

Meng, 49, was arrested at Vancouver International Airport in December 2018 on charges of committing bank fraud in the United States. While her case passed through the Canadian legal system, she was placed under house arrest for more than two years.

Her legal team has extracted internal documents from HSBC through a court in Hong Kong, and they hope to refer to these documents at the final hearing of the case scheduled for August.

In particular, the defense claimed that the two HSBC managing directors reviewed Meng’s presentation of Huawei’s Iran business submitted to HSBC. They stated that it clarified the ownership structure of Skycom.

On Tuesday, Meng and her legal team appeared in the Supreme Court of British Columbia on the first day of a two-day hearing. They will argue that more evidence should be added to support her case.

Mark Sandler, Meng’s defense attorney, told the court that the evidence showed that the U.S. argument was “defective and forced the court to no longer rely on them.”

The prosecutor representing the Canadian government argued that the evidence and arguments are beyond the scope of the extradition hearing.
