Well, 15 papers would not be whole work. Honestly this portion was forced onto me that it would be interesting. The idea is to choose 4 speeches from both of the presidents from same instances (meaning g20 summit, un summit so on). Where 2 of them would be from international actions and the remeaning 2 from domestic (annual meeting perhaps).
And then show on these speeches the signs of Chinese foreign policy styles – Low profile (hu Jintao) and assertive/striving for achievement (xi jinping).
