How are the general principles of the CISG interpreted when dealing with a dispute?

What will be an ideal response?

The CISG calls for courts to look to the general principles on which the convention is based when interpreting its provisions, but it gives no list of general principles. It is for the courts to divine those principles. The following two have been suggested: (1) A party to a contract has the duty to communicate information needed by the other party, and (2) parties have the obligation to mitigate damages resulting from a breach. Both concepts appear, in varying forms, throughout the convention. Although the CISG does not give a list of general principles, it does set out the mechanism for determining them. They must be derived (as is the case for the suggestions listed above) from particular sections of the convention and then extended, by analogy, to the case at hand.
