In this memo, Meng's lawyers raised several key points accusing HSBC of helping the U.S. government build a case against her.So far the only evidence that U.S. prosecutors use to accuse Meng of bank fraud is a PowerPoint file provided by HSBC. The file has been playing a central role in building a case against Meng as the U.S. accused the company of violating U.S. sanctions on Iran. For instance, the U.S. accused Huawei of using skycom as its unofficial subsidiary to conceal its operations in Iran and violating relevant sanctions. But two really important pieces of information in that PowerPoint went missing. The first, skycom was Huawei's business partner in Iran. And second, Huawei conducts normal business activity in Iran and provides civilian telecommunication solutions. Most lawyers claim both pieces of information were clearly delivered by Meng to an HSBC banker in Hong Kong in 2013. But later such information was taken out when they were presented as the evidence against Meng. Now the questions are how did they go missing,was it a deliberate omission by HSBC or was the bank under pressure to do so. Now Meng's lawyer is saying that HSBC knew about skycom's business in Iran from the beginning and it also understood skycom's relationship with Huawei and they will provide evidence to support these claims. In the next proceeding on June 23rd, the court will hear evidence and arguments from both prosecutors and Meng's lawyers, and the points made by this memo are expected to be the focal point of debate
