It may be Vague as either it may not suited you or may be you dint find any content. Regarding confusion here I list down where China backtracked from their stance as the sole purpose was to snub India:-
1) China said Indian Kashmir as India controlled Kashmir and P0K as part of North Pakistan.
Back Tracked:- After discussion with Indian ambassador, It removed P0K as North Pakistan from Xinhua.
2) China earlier said there were no Army present in P0K
Back Tracked: Now they say that Chinese army was in P0K to help flood victims.

You may also check Xinhua as well.
3) China said earlier that it is not building any dam on Brahmaputra River(Yarlung-Tsangpo) in Nov 2009.
China denies building dams on Brahmaputra: Foreign secretary - The Times of India
Back Tracked: In Apr 2009, It said it is building very small dam on the same river almost 1000 Km away from India.

The point, I reiterate, While India-China will grow economically. China will always do things to snub India as this will gain them psychological advantage.
