This email is from China domain name registration center, which mainly deal with the domain name registration in China. We received an application from [a third party] on September 10, 2012. They want to register ” [your brand name] ” as their internet keyword and China/Asia (CN/ASIA) domain names. But after checking it, we find this name conflicts with your company. In order to deal with this matter better, so we send you email and confirm whether this company is your distributor or business partner in China or not?
Alternatively, you may take steps to register your brand name in China on your own accord.
