Thai authorities have formally appealed to the international community following renewed land-mine explosions near the border with Cambodia, including a recent incident that wounded a foreign national.

The Thailand Mine Action Centre (TMAC) confirmed that anti-personnel mines of type PMN-2 — previously unseen in Thailand’s arsenal — were discovered in territory claimed by Thailand.

Officials say the mines were newly laid, not remnants of past conflict, and call the placement a blatant breach of the Ottawa Treaty to which both Thailand and Cambodia are signatories.

On Saturday, a 26-year-old man from China stepped on a land mine while reportedly crossing the border at a disputed area in Sa Kaeo Province.

He was hospitalised and remains in stable condition.

The incident triggered a strong reaction from the Thai army, which reiterated previous accusations that Cambodian forces have been laying fresh mines along the frontier.

The army emphasised that ongoing demining efforts are underway, yet new devices continue to surface.

The episode follows an earlier event in July 2025, when three Thai soldiers were injured — one losing a leg — after stepping on a land mine during a patrol near the border in Ubon Ratchathani Province.

The mine involved was also identified as PMN-2, and Thai experts have argued that its condition indicates recent deployment, not leftover ordnance from earlier conflicts.

TMAC’s public statement condemned the placement as a premeditated act endangering both military personnel and civilians, warning that the mines amount to a serious violation of international humanitarian law.

In light of repeated detonations and the discovery of additional mines, the Thai government has formally submitted a complaint to the United Nations, urging an international investigation.

The complaint cites multiple incidents between mid-July and late November 2025, including alleged cross-border attacks and deliberate planting of new mines inside Thai territory, actions that breach Article 2(4) of the UN Charter and the Ottawa Treaty’s prohibitions.

Diplomatic channels have reopened as Thai and Cambodian security officials prepare for renewed border talks under the General Border Committee (GBC) framework, with land-mine clearance and border incursions high on the agenda.

While Cambodia has questioned aspects of the allegations and called for adjudication under the International Court of Justice (ICJ), Thailand insists that the evidence shows deliberate and recent violations.

TMAC and the Thai government have called on Phnom Penh to cooperate fully with demining efforts and submit those responsible for placing mines to accountability.

The discovery of fresh PMN-2 mines and the resulting human casualties have dramatically escalated tensions along the border.

With the ministry now urging international intervention and humanitarian demining, both nations face growing pressure to deliver concrete action — or risk further instability in a sensitive frontier region.
