translate English to French: (a) It should be recognized that the arrangements regarding exchange of information worked out by country A with country B need not parallel those worked out between country A and country C or between country B and country C. The arrangements should in the first instance be responsive to the needs of the two countries directly involved and need not be fully parallel in every case just for the sake of formal uniformity.
a) Il convient de reconnaître que les dispositions concernant l'échange de renseignements arrêtées par le pays A et le pays B n'ont pas besoin de correspondre à celles qui auront pu être mises au point entre le pays A et le pays C ou le pays B et le pays C.
