I think you would get an an additional Chinese licence if you added another licence to your existing Chinese licence. As far as I know, that won't convert the licence type, only add add to the number of allowed installs the certificate allows.
I think you would need to buy an International licence separately to get one of those.
But I am not an expert on the finer details of the licencing. This kind of question is best sent to sales@ unless it's something covered by the licencing FAQ.
