Cluster Munitions Coalition

The Convention on Cluster Munitions was signed by 94 states when it opened for signature in Oslo, Norway on 3 December 2008.  On 16 February 2010, only 15 months later, the 30th state ratified the Convention, triggering its entry into force on 1 August 2010. Now that the Convention has taken effect, States Parties are bound by all of its terms.

Since the Convention entered into force, it is no longer open for signature and states can no longer sign and then ratify. States must now become bound through the process of “accession” which has the same effect as ratification.  Signatory states must still ratify the Convention now that it has entered into force.  Each country that has signed to Convention must still ratify it in order to become a State Party bound by the Convention’s provisions.

For the 30 states that ratified and triggered the Convention’s entry into force, it also entered into force for those states nationally on the same day – 1 August 2010 – making them States Parties to the Convention.  For all states that subsequently accede to or ratify the Convention, it enters into force on the first day of the sixth month after their ratification or accession.

The CMC urges as many states as possible to accede to or ratify the Convention and promote its norms.
