Thailand has formally demanded that the families of states signing the anti-personnel landmine ban dispatch an independent fact-finding mission to investigate what Bangkok describes as repeated breaches by Cambodia.

The move comes after several recent incidents in which Thai military personnel reportedly suffered severe injuries after stepping on mines along the disputed Thai–Cambodian border.

Foreign Minister Sihasak Phuangketkeow told reporters in Geneva that Thailand will resort to the compliance mechanisms of the Anti-Personnel Mine Ban Convention and is prepared to request its first-ever formal fact-finding mission under the treaty.

He underlined that Cambodia, which is also a State Party, appears to have violated its obligations by planting new anti-personnel mines in territory claimed by Thailand.

The demand follows multiple incidents this year — including at least one in which three Thai soldiers were seriously wounded when their patrol tripped a mine in territory Thailand regards as its own.

Thai authorities assert that all anti-personnel mines held by Thailand had long been destroyed or, if any remained, were exclusively for training and not deployed operationally.

They contend the mines responsible for the recent explosions were newly laid by Cambodian forces.

According to a letter submitted on twenty-four July twenty twenty-five by Thailand’s Permanent Representative to the United Nations, the complaint seeks clarification from Cambodia under Article eight, paragraph two of the Convention, allowing a State Party to request explanations for possible non-compliance.

Thailand simultaneously asked the presidency of the Convention’s twenty-second Meeting of States Parties, the United Nations Secretary-General, and relevant civil society organisations to take appropriate action.

Thailand’s position underscores that the contested border area, including the site of recent explosions, is entirely Thai territory, and that the planting of new mines constitutes not only a breach of the Convention but an infringement of Thai sovereignty and a serious threat to civilian and military safety.

Cambodian authorities, through the Cambodian Mine Action and Victim Assistance Authority, have firmly rejected the allegations.

They insist Cambodia remains committed to the Convention, denies having laid any new mines, and says Thailand’s claims are unsubstantiated and harmful to bilateral trust.

By invoking the Convention’s compliance mechanism and calling for an unprecedented fact-finding mission, Thailand is elevating its landmine allegations into a formal international dispute.

Whether this results in a comprehensive investigation or deepens longstanding border tensions will depend on the actions of the treaty’s governing bodies and the wider international community.
