Yes. Correct. Also Hong Kong won't rule until you file taxes and then may not grant unless you proof tax payment elsewhere. I would strongly advise against Hong Kong for that purpose. There is a reason why Hong Kong agents help the Chinese with BVI companies and no longer Hong Kong.You have to apply for offshore status in HK. I have heard it is not so easy to get it approved.
In SG, you only have to prove you don't manage the company from SG. Should be much easier.
Singapore is easier. But sure about above post regarding office but Sovereign tells me otherwise.
