Rumour mill has it that it was more about tax evasion/fraud than manufacturing airsoft since AFAIK HK is different from the mainland (HK SAR, same as Macau SAR). Essentially they're "autonomous" provinces of China and can pretty much do whatever the hell they want (except military defense and some other stuff). They have separate legislative and judicial powers from the mainland so unless it's illegal to manufacture airsoft in HK it won't be because of that (and anyways that would mean a tonne of other HK based companies will also have been shut down too).
