Mexico: Ratification of Treaty on the Non-Proliferation of Nuclear Weapons (NPT)

Action type
Government of the United States of America
21 January 1969
At the time of signature of the Treaty by Mexico, the Ambassador of Mexico made a statement, by a note to the Secretary of State dated July 26, 1968, a translation of which reads as follows:
“In signing the Treaty on the Non-Proliferation of Nuclear Weapons . . ., I have the honor to state that the Government of Mexico understands:
“1.  That, in view of Article VII of the Treaty, none of the provisions of the Treaty shall be interpreted as affecting in any way the rights and obligations of Mexico as a State Party to the Treaty for the Prohibition of Nuclear Weapons in Latin America (Tlatelolco Treaty), opened for signature on February 14, 1967, and on which Treaty the United Nations General Assembly adopted Resolution 2286 (XXII) of December 5, 1967; and
“2.  That, at the present time, any nuclear explosive device may be used as a nuclear weapon, and that there is no indication that in the near future it will be possible to manufacture nuclear explosive devices that are not potentially nuclear weapons.  Nevertheless, if technological progress should change that situation, it would be necessary to amend the pertinent provisions of the Treaty, in accordance with the procedure established therein.”
