Summary: State Party Congo ratified the convention on 2 September 2014. It has participated in meetings of the convention, but not since 2015. Congo voted in favor of a United Nations (UN) resolution on the convention in December 2018. It has elaborated its views on several important issues relating to the interpretation and implementation of the convention.
Congo states that it has never used, produced, or transferred cluster munitions, and does not possess any stocks, including for training or research. It must submit a transparency report for the convention to formally confirm this cluster munition-free status.
The Republic of the Congo(Congo-Brazzaville) signed the Convention on Cluster Munitions on 3 December 2008, ratified on 2 September 2014, and the convention entered into force for the country on 1 March 2015.
Congo has not enacted implementing legislation for the convention, but in the past officials have expressed interest in doing so. 
As of 25 June 2019, Congo had not submitted its initial Article 7 transparency report for the Convention on Cluster Munitions, originally due by 28 August 2015. Timely submission of the report is a legal obligation.
Congo participated in several meetings of the Oslo Process that created the Convention on Cluster Munitions and joined in the consensus adoption of the convention in Dublin in May 2008. 
Congo has attended most of the convention’s meetings, but not since 2015.  It was invited to, but did not attend, the convention’s Eighth Meeting of States Parties in Geneva in September 2018.
In December 2018, Congo voted in favor of a UN General Assembly (UNGA) resolution promoting implementation of the Convention on Cluster Munitions.  It has voted in favor of the annual UNGA resolution promoting the convention since it was first introduced in 2015.
Congo has expressed concern at the use of cluster munitions in Syria. 
In 2013, Congo elaborated its views on several important issues concerning interpretation and implementation of the convention. Congo’s National Mine Action Focal Point informed the Monitor that Congo “is not willing to assist any country with prohibited acts” under the convention, nor “to use its national territory for transit of these weapons or the stockpiling of cluster munitions and landmines belonging to a foreign army.”  The official also informed the Monitor that Congo agreed with the views of a number of States Parties to the convention and of the Cluster Munition Coalition (CMC) that investment in the production of cluster munitions is also prohibited by the convention. 
Congo is party to the Mine Ban Treaty. It is not party to the Convention on Conventional Weapons.
Use, production, transfer, and stockpiling
Congo stated in 2011 that it has never used, produced, or exported cluster munitions.  Congo also stated that it has no stockpiles of cluster munitions on its territory, including for training or research purposes. 
Congo must provide a transparency report for the convention to formally confirm it does not possess stocks.
Previously, in 2010, a Ministry of Defense official said Congo once possessed Soviet-made cluster munitions supplied for use with MiG-21 aircraft.  In 2011, Congo stated that the destruction of an arms depot in Maya-Maya during the conflict in 1997–1998 dispersed explosive weapons over a wide area, including RBK-250 and RBK-500 cluster bombs.  Subsequent clearance of the site destroyed ordnance including PTAB-2.5M and AO-1SCh submunitions.  Cluster munitions were not among unexploded ordnance created by a series of explosions at a munitions storage depot in Brazzaville on 4 March 2012 that killed more than 200 people. 
 In September 2015, Congo informed States Parties that it is reviewing the national implementation measures required to enforce the convention’s provisions. Statement of Congo, Convention on Cluster Munitions First Review Conference, Dubrovnik, 8 September 2015.

 In September 2011, Congo stated that it had no stockpiles of cluster munitions on its territory. In May 2013, Congo reported that it had destroyed its remaining 372 antipersonnel mines held for training and research purposes following the massive explosions in a weapons depot in Brazzaville in March 2012 and was now a country fully free of landmines and cluster munitions.

 An assessment found that cluster munitions were not found among the unexploded ordinance or other stockpiled munitions in the depot.
