Ok, and if there’s evidence of offences, investigate it appropriately. Financial records, on their own, generally don’t indicate to any great degree of detail what payments are for. Bank statements and wire transfer records don’t show that. It appears that that inevitable and normal ambiguity is being spun to suggest something nefarious, without anything specific to articulate suspicion. Have they actually gone to any efforts to find that out?
If the issue is simply one of having a financial or business relationship with a counterparty in China, that’s a net that will catch a lot of people, without anything necessarily being illicit.
