If the iphone 5s of t mobile can be used in China?

i wanna know if the iphone 5s of t mobile is unlocked?
I see that in web it is contract free but not unlocked, is there any difference between contract free and unlocked? When i come back to china, if the t mobile still can be used?
If it can be used, need i use the sim of t mobile for 40 days in US to unlock iphone 5s?

Thank you
