Actions reported in the period 1 January to 31 December 2011
The following list shows actions reported, if any, during the period 1 January
to 31 December 2011 with regard to multilateral arms regulation and disarmament
agreements. a The order in which the agreements are listed below are according to the
date of signature or opening for signature. The total number of parties for each treaty
or agreement has been calculated based on information received from the depositaries.
A new State party in the following list includes the date of deposit, to the
respective depositary, of the State’s instruments of ratification, and are further
noted as follows, if applicable: (a) = accession, (A) = acceptance, (AA) = approval,
(P) = consent to be bound, and (s) = succession. b
In the case of multi-depositary clauses, depositary action may be completed with
one or more of the several depositaries. The following notation indicates where the
reported action was completed: (M) = Moscow, (L) = London and (W) = Washington.
Certain treaties that establish nuclear-weapon-free zones (Bangkok Treaty,
CANWFZ Treaty, Pelindaba Treaty, Rarotonga Treaty and Treaty of Tlatelolco) have
associated protocols concerning security guarantees from the nuclear-weapon States
and some also have protocols for States outside the zone of application, but which have
some territory within the zone. They are at different stages with regard to signature,
ratification and entry into force. Full details can be found at http://disarmament.un.org/
