Obviously, it doesn't make sense 😉 Unfortunately, it's hard to understand why you're getting that error since you're not a customer from China. Have you, maybe, accidentally purchased a subscription that was meant for the Chinese market? Or, accidentally installed the Chinese language version of AE first?
Since this is mainly a public user-to-user forum, with only limited Adobe Employees around, I'd suggest to get in touch with Adobe Customer Care by visiting the following link:

They can help you figure out what's the matter and, hopefully, sort this out. Do keep in mind that it's the weekend right now and support won't be available until Monday.
