It is a very positive signal coming from the Chinese Ambassador regarding the expansion of a bilateral trade between India and China.  Also, it is very enlightening to note that the Chinese government is willing to address all the outstanding legitimate issues between these two countries whether they are in the arena of common borders, Tibet or flow of water.  Open and positive line of communication is essential to solve all mutual problems, but the only main ingredient of these dialogues ought to be that the end result should be fraught with 'win-win' situation.  Knowing what I know of the Chinese dealings with other nations, their main motive is "China first" which means it is good if it is good for China without any consideration to the other party's interest.  Hence, it is very crucial for the Indian government not to agree to any Chinese suggestions about the bilateral trade unless it is mutually beneficial.
