Here’s the actual statement: https://www.mha.gov.sg/media-room/newsroom/singapore-investi...

Singapore’s main complaint is that the FBI/DOJ didn’t compel Supermicro to cooperate fully with their investigation. It’s very possible cronyism played a part with this administration, but given that the DOJ brought charges against Supermicro executives earlier this year and subpoenaed the company, I wouldn’t be surprised if they were simply focused on their own investigation and/or didn’t have the legal authority to force them to cooperate.
