The Unwritten Rule Is the Rule
The US government's failure to specify Hong Kong's status in AI export and model-access restrictions is itself a regulatory choice — one that transfers the compliance burden entirely onto private institutions. When Goldman Sachs cannot confirm whether Hong Kong users are banned from restricted AI models , the institution is not encountering a bureaucratic delay; it is absorbing a political decision that Washington has declined to make explicit. Compliance teams do not have the option to wait. They default to the more restrictive interpretation, which means Hong Kong users are functionally treated as mainland Chinese users for AI access purposes — not because the law says so, but because no institution can afford to be wrong in the other direction. That de facto restriction, produced by silence rather than statute, is the enforcement reality on the ground.
