Liechtenstein: Accession to Treaty on the Non-Proliferation of Nuclear Weapons (NPT)

Action type
Government of the United States of America
20 April 1978
The instrument of accession to the Treaty by Liechtenstein contains a declaration, a translation of the text of which reads as follows:
“Noting that the Treaty is intended to prevent States which do not possess nuclear weapons from producing such weapons and other nuclear explosive devices or acquiring them, Liechtenstein hereby accedes to the Treaty with the view that its provisions are directed exclusively at the achievement of that goal and will not have the effect of limiting the use of nuclear energy for other purposes.
“Availing itself of this occasion of the deposit of its instrument of accession, Liechtenstein makes the following declaration:
1.  Liechtenstein notes that, according to Article IV, research, production, and use for peaceful purposes in the nuclear sector are not governed by the prohibitions contained in articles I and II.  Such activities specifically include the entire field of energy production and related operations, research and technology in the sector of future generations of nuclear fission or fusion reactors, and the production of isotopes.
2.  Liechtenstein defines the term ‘source or special fissionable material,’ used in article III, in conformity with the current article XX of the Statute of the IAEA.  A modification of this interpretation shall require the formal agreement of Liechtenstein.
Furthermore, Liechtenstein will accept only such interpretations and definitions of the concepts ‘equipment or materials specially designed or prepared for the processing, use or production of special fissionable material,’ mentioned in article III(2), as it has expressly approved.
3.  Liechtenstein understands that application of the Treaty and particularly the control measures will not lead to discrimination against Liechtenstein industry in international competition.”
