This fact is already known to many of those period.It was just officialised now, that is all. Nehru was treated as a child by Chou En Lai. CHou has expresed his intention very clearly in Calcutta ( i dont remember exactly where ) when a Golden ring was gifted to him. After wearing the ring, he said ( declared ) that India is in his hands. Our leader (Nehru ) such a goose, dont understood what he meant, but realised when china attacked us.
