"In my letter to you of the 24th November 1964, concerning the disposition of Malawi's inherited treaty obligations, my Govern ment declared that with respect to any multilateral treaty which was applied or extended to the former Nyasaland Protectorate, any Party to such a treaty could on the basis of reciprocity rely as against Malawi on the terms of that treaty until Malawi notified its depositary of what action it wished to take by way of confirmation of termination, confirmation of succession, or accession.
"I am to inform you as depositary of this Convention that the Government of Malawi now wishes to terminate any connection with this Convention which it might have inherited. The Govern ment of Malawi considers that any legal relationship with the aforementioned Convention and Statute on the Régime of Navigable Waterways of International Concern, Barcelona, 1921 which might have devolved upon it by way of succession from the ratification of the United Kingdom, is terminated as of this date."
