The problem: why your bank account was closed or rejected
The most common failure point occurs at the intersection of nationality and corporate structure. A mainstream US or European fintech or bank sees a Chinese national as the Ultimate Beneficial Owner (UBO) of a British Virgin Islands (BVI) company and their internal risk scoring categorises the application as high-risk. This often triggers an automated rejection without human review. The compliance cost of properly investigating your profile is deemed higher than the potential revenue from your account. You might be told the bank "cannot serve your industry" or that you are "outside their risk appetite", which are generic reasons for a specific bias.
For businesses that do get an account open, closure is a constant threat. This is common with popular fintech platforms that have not fully stress-tested their compliance back-office. A transaction that appears normal for an international business, like receiving a large wire from a Hong Kong entity or sending funds to a supplier in a specific jurisdiction, can trigger an automated flag. The compliance team, often inexperienced with complex international structures, opts to terminate the relationship rather than perform enhanced due diligence. This is especially true if you are using US-based fintechs fronted by small community banks who are ill-equipped to handle the perceived risks of US-China trade and investment flows.
