15-11-1996

Argentina reiterates the reservation made on ratification of the Constitution of the Universal Postal Union, signed at Vienna, Austria, on 10 July 1964, by which the Argentine Government expressly stated that article 23 of that organic charter neither referred to nor included the Islas Malvinas, South Georgia, the South Sandwich Islands or Argentine Antarctica. The Argentine Republic therefore reaffirms its sovereignty over those territories which form an integral part of its national territory. It also recalls that the United Nations General Assembly adopted resolutions 2065 (XX), 3160 (XVIII), 31/49, 37/9, 38/12, 39/6, 40/21, 41/40, 42/19 and 43/25, in which the existence of a dispute about sovereignty is recognized and in which the Governments of Argentina and the United Kingdom of Great Britain and Northern Ireland are requested to enter into negotiations with a view to settling the dispute and finding a peaceful and final solution to the problems outstanding between the two countries, including all questions concerning the future of the Islas Malvinas, in accordance with the Charter of the United Nations.
Similarly, the Argentine Republic points out that the provision contained in article 30, paragraph 1, of the Universal Postal Convention on the circulation of postage stamps valid in the country of origin will not be considered obligatory for the Republic where any such postage stamps distort Argentina's geographic and legal reality, without prejudice to the application of paragraph 15 of the joint Argentine-British Declaration of 1 July 1971 on communications and movement between Argentina's continental territory and the Islas Malvinas, approved by exchange of letters between the two Governments on 5 August 1971.
