6. The plenipotentiaries of the United States of America further declare that the participation of the United States of America in the Convention for limiting the Manufacture and Regulating the Distribution of Narcotic Drugs, signed on this date, does not involve any contractual obligation on the part of the United States of America to a country represented by a régime or entity which the Government of the United States of America does not recognise as the Government of that country until such country has a government recognised by the Government of the United States of America.

Salvador
(April 7th, 1933 a)
(a) The Republic of Salvador does not agree to the provisions of Article 26, on the ground that there is no reason why the High Contracting Parties should be given the option of not applying the Convention to their colonies, protectorates, and overseas mandated territories.
(b) The Republic of Salvador states that it disagrees with the reservations embodied in Nos. 5 and 6 of the Declar ations made by the plenipotentiaries of the United States of America regarding Governments not recognised by the Government of that country; in its opinion, those reservations constitute an infringement of the national sovereignty of Salvador, whose present Government, though not as yet recognised by the United States Government, has been recognised by the majority of the civilised countries of the world. Their recognition is due to their conviction that that Government is a perfectly constitutional one and affords a full and complete guarantee of the performance of its international duties, inasmuch as it enjoys the unanimous, decided and effective support of all the inhabitants of the Republic, whether citizens of the country or foreigners resident therein.
As it respects the internal régimes of other nations, the Republic of Salvador considers that the Convention in question, being of a strictly hygienic and humanitarian character, does not offer a suitable occasion to formulate such political reservations as have called forth this comment.
