The Kingdom of Lesotho signed the Mine Ban Treaty on 4 December 1997 and ratified it on 2 December 1998, becoming a State Party on 1 June 1999. Lesotho believes that existing legislation is sufficient to enforce the antipersonnel mine prohibition domestically. 

Lesotho’s most recent attendance at a meeting of the treaty was at the Tenth Meeting of States Parties to the Mine Ban Treaty in Geneva in November-December 2010. Lesotho did not attend the Third Review Conference in Maputo in June 2014 nor subsequent Meetings of States Parties. Lesotho last submitted a Mine Ban Treaty Article 7 transparency report in 2011, where it indicated that all information remained unchanged from previous reports. On 5 December 2018, Lesotho voted in favor of UN General Assembly resolution 73/61 promoting universalization and implementation of the convention, as it has done in previous years. 

Lesotho is party to the Convention on Conventional Weapons and Protocol V on explosive remnants of war, but not its Amended Protocol II on landmines. Lesotho is party to the Convention on Cluster Munitions. 

Lesotho has never used, produced, imported, exported, or stockpiled antipersonnel mines, including for training purposes.
