The Republic of Vanuatu joins the Convention on Cluster Munitions

[Geneva, 08 September 2025] – The Convention on Cluster Munitions (CCM) warmly welcomes the Republic of Vanuatu as its 112th State Party following the deposit of its instrument of accession with the Depositary, the Secretary-General of the United Nations.

By acceding at this time, Vanuatu reaffirms the universal responsibility to protect civilians from the impact of cluster munitions and strengthens international humanitarian law in a period of global distress. This decision reflects principled solidarity with affected States and a clear commitment to humanitarian norms.

Small Island States such as Vanuatu continue to demonstrate that all States, regardless of size or circumstance, have a vital role in reinforcing humanitarian disarmament. Their accession underscores the momentum of the CCM and reinforces the global consensus against cluster munitions.

With Vanuatu’s accession, the Convention now counts 112 States Parties and 12 Signatories. Having entered into force in 2010, the CCM remains a landmark instrument of international humanitarian law, ensuring assistance to victims, clearance of contaminated land and a permanent prohibition on these weapons.

The President of the Thirteenth Meeting of States Parties, Ambassador Carlos D. Sorreta of the Philippines, issued a letter welcoming Vanuatu’s accession. Click here to read the letter.
