Japan’s ambassador to Cambodia has pledged to report the ongoing Cambodia-Thailand border dispute directly to the government in Tokyo, according to Cambodia’s Human Rights Committee.
In a statement posted on Facebook on February 12, 2026, the committee said Ueno Atsushi, Ambassador Extraordinary and Plenipotentiary of Japan to Cambodia, committed during a meeting with Keo Remy, president of the Cambodian Human Rights Committee, on February 9, 2026.
The committee said the discussion focused extensively on what it described as Thailand’s incursions into Cambodian territory.
Despite a ceasefire agreement signed on December 27, 2025, the committee claimed that around 90,000 Cambodian displaced people have yet to return home safely. It is alleged that Thai forces continue to occupy Cambodian land unlawfully and have taken measures, including the deployment of barbed wire and shipping containers.
The Cambodian Human Rights Committee said these actions are having a serious impact on the fundamental rights of displaced civilians, particularly women, children, infants, elderly people, the sick, and those with disabilities. It cited restrictions affecting access to education, healthcare, adequate housing, and freedom of movement.
The statement further accused Thai forces of looting property and constructing new buildings in an attempt to establish what it called a new identity on Cambodian sovereign territory. It also alleged that during fighting in late December 2025, Thai forces used cluster munitions, toxic smoke, and fighter aircraft, including F-16, Gripen, and T-50 jets, in attacks that damaged civilian homes and infrastructure.
Thailand has not publicly responded to these specific allegations.
On December 27, 2025, the Japanese Embassy in Phnom Penh issued a statement expressing full support for the ceasefire agreement reached between Cambodia and Thailand that same day. Japan said it strongly hoped both sides would fully implement the agreement.
The embassy added that the Japanese government intends to continue diplomatic efforts to help ease tensions and encourage compliance with the ceasefire, in cooperation with the United States and member states of the Association of Southeast Asian Nations.
The Cambodian government has recently reported that more than 110,000 Cambodian civilians have been displaced and lost land and homes as a result of what it describes as Thailand’s acts of aggression.
The border dispute remains a sensitive issue, with humanitarian and diplomatic implications extending beyond the two neighbouring countries.
