Sri Lanka acceded to the APMBC in December 2017, with the convention entering into force on 1 June 2018. In its first transparency report submitted in November 2018, Sri Lanka reported stockpiled antipersonnel mines under its ownership or possession.

Article 4 of the Anti-Personnel Mine Ban Convention (APMBC) requires that signatories undertake to destroy or ensure the destruction of all stockpiled anti-personnel mines it owns or possesses, or that are under its jurisdiction or control, as soon as possible but not later than four years after the entry into force of the mine ban treaty for that State Party.

On 30 September 2021 Sri Lanka reported it had fulfilled its obligation. In total, Sri Lanka reported having destroyed 12,000 landmines, almost a year earlier than the deadline set to the country.
