The Kingdom of Cambodia signed the Mine Ban Treaty on 3 December 1997 and ratified on 28 July 1999, becoming a State Party on 1 January 2000. Domestic implementation legislation—the Law to Prohibit the Use of Anti-personnel Mines—took effect on 28 May 1999.
Cambodia has attended all of the Mine Ban Treaty’s Review Conferences held in 2004, 2009, and 2014 as well as most of the treaty’s Meetings of States Parties and many of the intersessional meetings held in Geneva, including in the Seventeenth Meeting of States Parties in Geneva in November 2018 and the intersessional meetings in Geneva in May 2019. It hosted the Mine Ban Treaty’s Eleventh Meeting of States Parties in December 2011.
Cambodia is party to the Convention on Conventional Weapons (CCW) and its Amended Protocol II on landmines and Protocol V on explosive remnants. It is not party to the Convention on Cluster Munitions.
There have been no allegations of new use of antipersonnel mines on the Cambodian border with Thailand since 2013.
In March 2013, three Thai soldiers were injured by what the Thai military described as newly planted mines near the Ta Kwai Temple in Phanom Dong Rak district. Cambodia investigated and in its report to States Parties found the mines were old, dating from the Cambodian civil war. Cambodia provided a copy of its investigation report to the Mine Ban Treaty Implementation Support Unit and the ICBL at the May 2013 intersessional meetings, and to the government of Thailand through diplomatic channels.
Other allegations made by Thailand of Cambodian use of antipersonnel mines on the Cambodian-Thai border in 2008 and 2009 were never resolved.
Production, transfer, stockpile destruction, and retention
Previously, the Royal Cambodian Armed Forces (RCAF) destroyed its declared stockpile of 71,991 antipersonnel mines between 1994 and 1998, and in February 1999 the RCAF Deputy Commander in Chief formally stated that the RCAF no longer had stockpiles of antipersonnel mines. In 2000, Cambodia reported an additional stockpile of 2,035 antipersonnel mines held by the national police that were subsequently destroyed. In 2013, Cambodia reported that while there have been no antipersonnel mine stockpiles in the country since 2001, “police and military units are still finding and collecting weapons, ammunitions and mines from various sources, locations and caches.” Discovered mines are supposed to be reported to the Cambodian Mine Action and Victim Assistance Authority (CMAA) and handed over to the Cambodian Mine Action Center (CMAC) for destruction. A Cambodian official has previously stated that newly discovered stocks are destroyed immediately.
Previous Article 7 reports document a total of 133,478 stockpiled antipersonnel mines that were found and destroyed from 2000 to 2008, including 13,665 in 2008; this included 9,698 by CMAC; 2,713 by HALO Trust; and 1,254 by Mines Advisory Group (MAG). Cambodia stated that these mines were “reported by local communities.” It is not clear why significant numbers of stockpiled mines were discovered each year through 2008, but none have been discovered since.
Cambodia has each year reported transfer of mines removed from mined areas to the CMAC training center and other operators for training purposes. In June 2011, the deputy secretary general of the CMAA told the Monitor that all mines held by Cambodia are fuzeless and that Cambodia retains no live mines for training. In its 2014 Article 7 report, Cambodia reported the transfer of 60 inert antipersonnel mines for use to train animals in landmine detection.
 The law bans the production, use, possession, transfer, trade, sale, import, and export of antipersonnel mines. It provides for criminal penalties, including fines and imprisonment for offenses committed by civilians or members of the police and the armed forces. It also provides for the destruction of mine stockpiles.
 Prak Sokhonn, Minister Attached to the Prime Minister and Vice-Chair of the Cambodian Mine Action and Victim Assistance Authority (CMAA), was elected president of the Eleventh Meeting of States Parties to the Mine Ban Treaty, which Cambodia hosted in Phnom Penh in November–December 2011 at Vimean Santepheap (the Peace Palace).
 See, Landmine Monitor 2013, Thailand Mine Ban Policy profile. According to a request made by the ICBL, Cambodia conducted a fact-finding mission to the site from 10–12 May 2013 that determined the Thai solders were injured by mines laid during the Cambodian civil war. It said its soldiers found indications of the incident on the same day, and recorded a GPS reference that differed from the reference declared by the Thai military. Cambodia stated that the incident took place to the side of, not on, a specially cleared path used for military-to-military meetings between the Thai and Cambodian military in the area. The Cambodian delegation provided copies of the report at the May 2013 intersessional meeting in Geneva.

 In October 2008, two Thai soldiers stepped on antipersonnel mines while on patrol in disputed territory between Thailand and Cambodia, near the World Heritage Site of Preah Vihear. Thai authorities maintained that the area was previously clear of mines and that the mines had been newly placed by Cambodian forces. Cambodia denied the charges and stated that the Thai soldiers had entered Cambodian territory in an area known to contain antipersonnel mines and were injured by mines laid during previous armed conflicts. In April 2009, another Thai soldier was reportedly wounded by an antipersonnel mine at the same location during further armed conflict between the two countries. In September 2009, Commander in Chief of the Royal Thai Army, Gen. Anupong Paochinda, stated that Cambodian troops were laying fresh mines along the disputed areas and close to routes where Thai soldiers make regular patrols.
