IPhone 4S (GSM China). Is this a Fake Apple?

I'm looking for an iPhone 4S. And, I found one with Model - A1431(GSM China). But, since "China" comes under the name, I'm little confused.

Is this iPhone Made-By-China? Not an original Apple product?
And, I found the device language to be Chinese.So, is there any way to make it English? Like, will it need an unlock or something?

It may sells in China, you can change to Chinese language in the settings.
