It is good to exchange dialogue to sort out any ill will about others.However, the main ingredient to achieve any kind of success from these discussion needs a sincere attitude without any hidden agenda.In case of China, that seriousness is missing which is clear from a historical fact of what happened in 1962 after Chou-en-Lai's visit to India.  One should not forget the Chinese slogan of Hindi Chini Bhai Bhai followed by an invasion on India.Past experience teaches us that India has to impose preconditions before initiating any serious dialogues with China, and those preconditions should include; helping India to become member of Nuclear Club, vacate Indian territories of POK and Arunachal Pradesh, condemn Pakistani known terrorists.
