Artikel 8

a. If either of the Contracting Parties considers it desirable to modify provision or provisions of the Agreement, or its Annex, the competent aeronautical authorities of the Contracting Parties shall consult in order to realise such modification(s). Such consultation shall begin within a period of 60 days from the date of the request. In case the said authorities arrive at an understanding about the modifications to be made, said modifications shall come into force after having been confirmed by an exchange of diplomatic notes.
b. Changes made by either Contracting Party in the specified routes except the change of points served by its designated air carrier(s) in the territory of the other Contracting Party, shall not be considered as modifications of this Agreement. The aeronautical authorities of either Contracting Party may therefore proceed unilaterally to make such changes provided however, that notice of any change shall be given without delay to the aeronautical authorities of the other Contracting Party.
