NEW YORK/LONDON—An internal investigation by HSBC Holdings PLC into Huawei Technologies’ connections to a suspected front company in Iran found that the Chinese telecommunications equipment maker maintained close financial ties to the firm years after purportedly selling the unit, documents reviewed by Reuters show.
The HSBC probe of Huawei came in late 2016 and 2017 as the bank was trying to get the U.S. Department of Justice (DOJ) to dismiss criminal charges for the bank’s own misconduct involving U.S. sanctions.
