Key Developments

Increasing use of craft mines by southern insurgency


The Kingdom of Thailand signed the Mine Ban Treaty on 3 December 1997 and ratified it on 27 November 1998, becoming a State Party on 1 May 1999. Thailand has not enacted domestic legislation to implement the Mine Ban Treaty. As it has reported since 2002, Thailand is still in the process of passing an executive measure, the Office of the Prime Minister Regulations Governing the Implementation of the Convention.[1]

Thailand submitted its thirteenth Mine Ban Treaty Article 7 report on 30 April 2011, covering calendar year 2010.[2]

Thailand attended the Tenth Meeting of States Parties to the Mine Ban Treaty in Geneva in November–December 2010, where it became co-chair of the Standing Committee on the General Status and Operation of the Convention. Thailand made interventions during sessions on enhancing international cooperation and assistance, assisting victims, clearing mined areas, and evaluation of the Implementation Support Unit.

At the intersessional Standing Committee meetings in Geneva in June 2011, in addition to its co-chair role, Thailand made interventions during the sessions on Article 3 under the General Status and Operation of the Convention on mines retained, clarifying some changes reported in its Article 7 report, and also on its clearance progress since receiving an extension on its Article 5 obligations. Thailand also made interventions during the sessions on victim assistance, international cooperation and assistance, and Implementation Support Unit funding models.

Thailand is not party to the Convention on Conventional Weapons.

Production, transfer, stockpile destruction, and retention

Thailand states that it has never produced or exported antipersonnel mines. Thailand formerly imported antipersonnel mines from China, Italy, the United States, and the former Yugoslavia. It completed destruction of 337,725 stockpiled antipersonnel mines on 24 April 2003.

In its Article 7 report submitted in 2011, Thailand reported that at the end of 2010, it retained 3,466 antipersonnel mines for training purposes, a reduction of 160 mines from the previous year.[3] Two hundred antipersonnel mines held by the army were transferred for training of new deminers, while 40 antipersonnel mines held by the Thailand National Police Department were retained. Thailand has never reported in any detail on the intended purposes and actual uses of mines kept for training—a step agreed by States Parties at the Review Conferences in 2004 and 2009.[4]

In June 2011 Thailand stated, “Inventories of mines retained will continue to be done so that our article 7 submissions accurately reflect mines in official possession.”[5] At the end of 2010, the Royal Thai Army retained 2,800 mines, the Royal Thai Air Force retained 581 mines, and the National Police Department retained 85 mines.[6] In June 2010, Thailand said that since the number of mines retained is high compared to the number used each year, it would review its retention and destruction plans.[7]

Thailand is not known to have undertaken physical modifications of its Claymore mine stockpile to ensure use only in command-detonated mode. Officials have previously stated that all units have received orders that Claymore mines are to be used only in command-detonated mode.[8]


The insurgency in southern Thailand has seen extensive use of command-detonated improvised explosive devices (IEDs). There are also reports of increased use of homemade, or so-called “craft mines”[9] or victim-activated IEDs. In May and July, rubber tappers were injured by victim-activated IEDs in Thanto district, Yala province. In May 2010 a rubber tapper lost his leg after stepping on a mine. In July 2010 a rubber tapper was killed by a mine.[10] In October 2010 a woman was injured after stepping on a mine while tapping rubber trees in Raman district, Yala province.[11] In January 2011 a woman rubber tapper was injured after she reportedly stepped on a mine in Narathiwat’s Bacho district.[12] No group has claimed responsibility for the explosive devices, but news reports frequently state that the mines are laid by insurgents seeking to expel ethnically Thai rubber plantation owners. A female soldier was injured after reportedly stepping on a mine near the site of an insurgent attack.[13]

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 landmines 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.[14] Cambodia and Thailand have never reached a resolution of this matter, and other States Parties have apparently not pursued a resolution of this serious compliance concern.[15]


[1] Interview with Lt.-Gen. Tumrongsak Deemongkol, Director-General, Thailand Mine Action Center (TMAC), Bangkok, 25 February 2010. Thailand’s Article 7 reports submitted from 2007–2009 state, “The issuing is still in progress.” The 2010 report apparently mistakenly dropped that phrase, as the regulations have not yet been adopted and are still in progress; they had not been entered into the Royal Thai Government Gazette as of late July 2010. TMAC reported in 2009 that the Sub-committee on Administration and Evaluation is responsible for this process, and that in early 2009 it was in the process of submitting the draft regulations to the National Committee for Humanitarian Mine Action for consideration. The draft was first developed by TMAC in 2002. Thailand has reported that the draft regulations have been pending approval of various entities each year. See Landmine Monitor Report 2009, p. 718, and previous editions.

[2] Previous Mine Ban Treaty Article 7 reports were submitted on 30 April 2010, 30 April 2009, 30 April 2008, 25 April 2007, 25 April 2006, 25 April 2005, 3 May 2004, 22 July 2003, 30 April 2002, 17 April 2001, 2 May 2000, and 10 November 1999.

[4] The Royal Thai Army, Navy, Air Force, and National Police Department initially retained a total of 4,970 antipersonnel mines for training. In the past 10 years, Thailand has reported that 504 mines have been consumed by its training programs. The number of retained mines did not change from 2001 to 2004. In 2005–2006, Thailand reduced the number of mines retained by 257. There were discrepancies in the reporting on the number of mines. See Landmine Monitor Report 2007, p. 665. In 2007, it reduced the number by another 1,063 mines. It appears that 63 of the mines retained by the National Police Department were consumed during training activities, and all of the 1,000 mines retained by the navy were simply destroyed, presumably because they were no longer deemed necessary. See Landmine Monitor Report 2008, p. 678. In 2008 and 2009, Thailand destroyed another 12 mines per year. In 2010, Thailand reported transferring 200 mines for training, apparently 13 M2, 84 M14, 39 M16, and 64 M26 antipersonnel mines. Statement of Thailand, Standing Committee on the General Status and Operation of the Convention, Mine Ban Treaty, Geneva, 20 June 2011; and Mine Ban Treaty Article 7 Report, Form D, 30 April 2011. The types transferred are not noted in the Article 7 report.

[5] Statement of Thailand, Standing Committee on the General Status and Operation of the Convention, Mine Ban Treaty, Geneva, 20 June 2011; and Mine Ban Treaty Article 7 Report, Form D, Geneva, 30 April 2011. The number of mines retained by the Air Force remains unchanged since 2006. It is unclear why different services retain mines and whether each has a training program for mine clearance.

[8] Interview with Lt.-Gen. Tumrongsak Deemongkol, TMAC, Bangkok, 19 March 2009. TMAC stated this in 2007 and 2008 as well. In its Article 7 report for 1999, Thailand reported that it had 6,117 M18 and M18A1 Claymore mines in stock.

[9] Craft landmines are explosive devices crafted out of locally available materials that are designed to detonate due to the proximity or activity of a human being. Such devices are banned under the Mine Ban Treaty.
