One of the first questions that always comes up is: Do I nead a Chinese domain to be able to rank and be used within Mainland China?
The short answer to this is no. In fact, many Chinese companies themselves work with a .com domain and don’t use a .cn domain.
Given that you most likely don’t have a ICP license, you probably won’t be able to get your hands on a .cn domain anyway, so feel free to ignore them.
Scams
If you are like me, you will most likely receive emails from people or companies in China claiming that company xxx is about to register your domain yyy.cn (yyy being your company name).
I personally always ignored them. If you want to play things safe, maybe talk to a legal expert and potentiall look into trademarks in Mianland China.
I just mention that to prepare you that this will happen and it happens to many people. How you deal with that will depend on your particular situation, company size, etc.
