State Party Colombia ratified the Convention on Cluster Munitions on 10 September 2015. It has participated in every meeting of the convention. Colombia has voted in favor of the key annual United Nations (UN) resolution promoting the convention every year since it was first introduced in 2015.
Colombia has never produced cluster munitions, though it imported them in the past and destroyed a stockpile of 72 cluster munitions and 10,832 submunitions in November 2009. Colombia is not retaining any cluster munitions for training or research purposes.
The Republic of Colombia signed the Convention on Cluster Munitions on 3 December 2008 and ratified it on 10 September 2015. The convention entered into force for the country on 1 March 2016.
Law 1604, adopted in December 2012, approved Colombia’s ratification of the convention and incorporated its provisions into domestic law. Colombia has reported this law and other legislation and decrees under its national implementation measures for the convention.
Colombia provided its initial Article 7 transparency report on 28 August 2016, and has submitted annual updated reports since then, most recently in May 2021.
Colombia participated in several meetings of the Oslo Process that produced the convention and said that its decision to join stemmed from its concern about the “humanitarian impact” of cluster munitions.
Colombia actively engages in the work of the Convention on Cluster Munitions. It has participated in every Meeting of States Parties of the convention, as well as the Second Review Conference held in November 2020 and September 2021, and the First Review Conference in 2015. Colombia also attended intersessional meetings in 2011–2015 and in May 2022. It has participated in regional workshops on the convention.
Colombia voted in favor of the key annual United Nations General Assembly (UNGA) resolution promoting the implementation of the Convention on Cluster Munitions in December 2021. It has voted in favor of the annual UNGA resolution on the convention since it was first introduced in 2015.
Colombia is a State Party to the Mine Ban Treaty. It is also party to the Convention on Conventional Weapons (CCW).
Colombia has provided its views on certain important issues related to the interpretation and implementation of the convention. In 2011 and 2010 responses to Monitor questionnaires, Colombia said it “absolutely rejects and prohibits any manner of transfer or storage of foreign cluster bombs in Colombian territory,” as well as “military operations with states not party to the convention in which they carry out exercises or actions prohibited by the Convention.” Colombia interprets the convention as prohibiting investment in the production of cluster munitions.
Production and transfer
In a May 2011 letter to the Monitor, Colombia stated that it has never produced cluster munitions. In the past, Colombia imported cluster munitions from Chile, Israel, and the United States (US). In 2010, Colombia stated that it has never transferred cluster munitions “to a third state.”
In 2012, Chile’s Ministry of National Defense shared a document with the Monitor detailing two transfers—totaling 191 cluster munitions—to Colombia in the 1990s: 132 250kg cluster bombs in 1997, and 55 250kg cluster bombs, four air-dropped 250kg cluster bombs, and one fin stabilizer for a CB-250kg cluster bomb in 1994.
In April 2012, an official from the Colombian Ministry of External Relations told the Monitor that the Colombian Air Force decided to stop using cluster munitions after an evaluation found that they did not meet the operational requirements or needs of Colombia.
In May 2009, Colombia’s then-Minister of Defense, Juan Manuel Santos, acknowledged that the Colombian armed forces had used cluster munitions in the past “to destroy clandestine airstrips and camps held by illegal armed groups” and said the submunitions sometimes did not explode and “became a danger to the civilian population.”
The Monitor has reported on the case of apparent cluster munition use by the Colombian Air Force at Santo Domingo in the municipality of Tame, Arauca department, on 13 December 1998, which killed 17 and injured 27 others. An investigation showed that a World War II-era “cluster adapter” of US origin was used to disperse several 9kg fragmentation bombs during the attack. In December 2012, the Inter-American Court of Human Rights (IACHR) published its verdict on the case, finding that the Colombian Air Force used an AN-M1A2 bomb, which it said met the definition of a cluster munition. The court found that Colombia should treat victims of the attack in accordance with its victim assistance obligations under the Convention on Cluster Munitions. In November 2017, the Supreme Court of Colombia upheld the decision.
Stockpiling and destruction
Colombia announced that it had completed the destruction of its cluster munition stockpile on 24 November 2009. It destroyed 72 cluster munitions (31 ARC-32 and 41 CB-250K cluster bombs) containing a total of 10,832 submunitions.
Colombia has not retained any cluster munitions or submunitions for research or training.
 The House of Representatives approved the draft ratification legislation, Bill 244, on 15 November 2012, after it received Senate approval as Bill 174 on 30 August 2012.
