At the time of signature, the Ambassador of Mexico, in a note dated April 10, 1972, made certain statements for the record. A translation of the Ambassador’s note reads as follows:
“On proceeding to the signature in the name of my Government of the Convention on the Prohibition of the Development, Production, and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction, I am informing Your Excellency that the Government of Mexico wishes to state for the record that:
“1. It remains convinced that the same reasons that made advisable the joint prohibition on the use of biological weapons and chemicals in the Geneva Protocol of 1925 exist now for endeavoring to follow an identical method regarding the prohibition of the development, production, and stockpiling of such weapons and their elimination from the arsenals of all States.
“2. It considers that the fact that the Convention now open for signature applies only to biological and toxin weapons should be considered, in accordance with the explicit provisions of resolution 2826 (XXVI) of the United Nations General Assembly, to which the Convention itself is annexed, as only a first step—the only one that can possibly be taken for the moment—toward achievement of an agreement that will similarly prohibit the development, production, and stockpiling of all chemical weapons.
“3. It notes that the Convention contains an express commitment to continue negotiations in good faith with a view to reaching early agreement on the prohibition of the development, production, and stockpiling of chemical weapons and on their destruction.
“4. It also notes that the General Assembly, in its resolution 2827 (A) (XXVI) requested the Conference of the Committee on Disarmament to continue, as a high priority item, negotiations with a view to achieving promptly the agreement sought on chemical weapons, and that in its resolution 2827 (B) (XXVI) it urged all States to undertake, pending achievement of such agreement, to refrain from all development, production, or stockpiling of those chemical agents for weapons purposes which because of their degree of toxicity have the highest lethal effects and are not usable for peaceful purposes.
“5. It is convinced that the success of the Convention on biological weapons will depend in the last instance on the outcome of the commitments referred to above.
“I avail myself of this opportunity to renew to Your Excellency the assurances of my very high and distinguished consideration.”
