Sri Lanka participated as an observer in the convention’s meetings, prior to its accession.

Production, transfer, and stockpiling
In its initial Article 7 report submitted in February 2019, Sri Lanka indicated that it has no stockpile of cluster munitions or production facilities for the weapon and it is not retaining any. 
In September 2018, Sri Lanka stated that it “has never used cluster munitions.”  Previously, Sri Lankan officials repeatedly stated that its armed forces did not possess cluster munitions and never used the weapon. 
Past allegations of use
Sri Lanka has emphatically denied claims that it used cluster munitions in 2008–2009 during the final months of its military operation against the Liberation Tigers of Tamil Eelam (LTTE) in the northern Vanni region.  In 2017, Sri Lanka commented to Cluster Munition Monitor that “With regard to the recent allegations of using ‘Cluster Munitions’ during the operations against LTTE terrorists, Sri Lanka Army, Sri Lanka Navy and Sri Lanka Air Force re-iterated their earlier stand that they have never used Cluster Munitions” 
In 2016, the UN High Commissioner for Human Rights (OHCHR) recommended that the government of Sri Lanka initiate an independent investigation into the alleged use of cluster munitions in past. 
The suggestion came after new evidence emerged in 2016 showing that since 2009, three mine clearance organizations have cleared cluster munition remnants, including unexploded submunitions, from at least six different sites in the north of the country.  Mine clearance organizations could not determine who used the cluster munitions or when, asserting that it “could have been any time within the last three decades.” 
The Sri Lankan Air Force possesses aircraft capable of delivering Soviet-made cluster munitions. A 2009 media article alleged that Sri Lankan forces used cluster munitions against the LTTE, while attacking Pudukkudyirippu Hospital.  The LTTE had light planes incapable of carrying them. The Indian Air Force possesses RBK-500 series cluster bombs and was involved in a military intervention against the LTTE in northern Sri Lanka in 1987–1990.
A 2011 report by a UN panel of experts on Sri Lanka noted the government’s denial and said that it was unable to reach a conclusion on the credibility of the allegation of use of cluster munitions by Sri Lanka. 
 Sri Lanka has participated as an observer in every Meeting of States Parties of the convention since 2011 and attended the First Review Conference in 2015.

 Paragraph 33 states: “In light of recent reports on new evidence that has emerged on the use of cluster munitions towards the end of the conflict, following similar allegations in the OHCHR investigation report, the High Commissioner calls for an independent and impartial investigation to be carried out.” OHCHR, “Promoting reconciliation, accountability and human rights in Sri Lanka,” A/HRC/32/CRP.4, 28 June 2016, p. 8.
 The Guardian published photographs that show clearance operators preparing to destroy the remnants of an RBK-500 AO-2.5RT cluster bomb. It reported that HALO Trust cleared 42 cluster munitions—likely submunitions—from sites near Pachchilapalli, which saw fighting between government and LTTE forces at the end of the war. HALO said it reported the clearance at the time by submitting the records to the government-run mine action center.
