(1) 

To the Congress of the United States: 

I am pleased to transmit to the Congress, pursuant to subsections 123 b. and 123 d. of the Atomic Energy Act of 1954, as 

amended (42 U.S.C. 2153(b), (d)) (the ‘‘Act’’), the text of an Agreement between the Government of the United States of America and 

the Government of the United Mexican States for Cooperation in 

Peaceful Uses of Nuclear Energy (the ‘‘Agreement’’). I am also 

pleased to transmit my written approval, authorization, and determination concerning the Agreement and an unclassified Nuclear 

Proliferation Assessment Statement (NPAS) concerning the Agreement. In accordance with section 123 of the Act, a classified annex 

to the NPAS, prepared by the Secretary of State, in consultation 

with the Director of National Intelligence, summarizing relevant 

classified information, will be submitted to the Congress separately. A joint memorandum submitted to me by the Secretaries of 

State and Energy and a letter from the Chairman of the Nuclear 

Regulatory Commission stating the views of the Commission are 

also enclosed. An addendum to the NPAS containing a comprehensive analysis of the export control system of Mexico with respect to 

nuclear-related matters, including interactions with other countries 

of proliferation concern and the actual or suspected nuclear, dualuse, or missile-related transfers to such countries, pursuant to section 102A(w) of the National Security Act of 1947 (50 U.S.C. 

3024(w)), is being submitted separately by the Director of National 

Intelligence. 

The Agreement has been negotiated in accordance with the Act 

and other applicable law. In my judgment, it meets all applicable 

statutory requirements and will advance the nonproliferation and 

other foreign policy interests of the United States. 

The Agreement contains all of the provisions required by subsection 123 a. of the Act. It provides a comprehensive framework 

for peaceful nuclear cooperation with Mexico based on a mutual 

commitment to nuclear nonproliferation. It would permit the transfer of material, equipment (including reactors), components, and information for nuclear research and nuclear power production. It 

would not permit the transfer of Restricted Data or sensitive nuclear technology. Any special fissionable material transferred could 

only be in the form of low enriched uranium, with the exception of 

small quantities of material for use in samples, standards, detectors, or targets or for such other purposes as the parties may agree. 

Through the Agreement, Mexico would affirm its intent to rely 

on existing international markets for nuclear fuel services involving sensitive nuclear technologies (i.e. enrichment and reprocessing), and the United States would affirm its intent to support these 

international markets and would agree to endeavor to take necessary and feasible actions to ensure a reliable supply of low enriched uranium fuel to Mexico.

The Agreement has a term of 30 years, although it can be terminated by either party on one year’s advance written notice. In the 

event of termination or expiration of the Agreement, key nonproliferation conditions and controls will continue in effect as long 

as any material, equipment, or component subject to the Agreement remains in the territory of the party concerned or under its 

jurisdiction or control anywhere, or until such time as the parties 

agree that such material, equipment, or components are no longer 

usable for any nuclear activity relevant from the point of view of 

safeguards. 

Mexico has a strong track record on nonproliferation and has 

consistently reiterated its commitment to nonproliferation. It is a 

party to the Treaty on the Non-Proliferation of Nuclear Weapons 

and has concluded a Comprehensive Safeguards Agreement and 

Additional Protocol with the International Atomic Energy Agency. 

Mexico has a strong system of nuclear export controls and has harmonized its controls with the Nuclear Suppliers Group guidelines. 

A more detailed discussion of Mexico’s domestic civil nuclear activities and its nuclear nonproliferation policies and practices is provided in the NPAS and its classified annex. 

I have considered the views and recommendations of the interested departments and agencies in reviewing the Agreement and 

have determined that its performance will promote, and will not 

constitute an unreasonable risk to, the common defense and security. Accordingly, I have approved the Agreement and authorized 

its execution and urge that the Congress give it favorable consideration. 

This transmission shall constitute a submittal for purposes of 

both subsections 123 b. and 123 d. of the Act. My Administration 

is prepared to begin immediately consultations with the Senate 

Foreign Relations Committee and the House Foreign Affairs Committee, as provided in subsection 123 b. Upon completion of the 30 

days of continuous session review provided for in subsection 123 b., 

the 60 days of continuous session review provided for in subsection 

123 d. shall commence. 

DONALD J. TRUMP. 

THE WHITE HOUSE, May 8, 2018.
