Hello Haruka: The statement is very well written, but there are a couple of minor grammatical errors. The noun phrase "foreign university" requires the article "a": "I expect that the experience of attending classes in a foreign university..." You will be probably be having more than one discussion with the foreign university students so it should be plural.: " ...and having discussions with diverse students..." Although the word "contribute" works, the word "help" is more to the point: "will help to improve these areas." This last one is more a personal preference. "Contribute" will work here as well. I hope this helps you and good luck with your application. Mike C

I think that a good communicative skill does not only mean the proficiency to speak English fluently but it also suggests be able to express personal opinions in the public freely and to appreciate other (exotic) cultures. I expect this experience attending your class (label the name of the university you wish to study in, e.g Melbourne University ) will enable me to have more extensive discussion with your students (local students, international students) from other countries (otherwise cultural backgrounds, since you mentioned about culture in the former paragraph) and improve my language proficiency. I am not a native speaker, but I just give you some opinions to express yourself more properly.
