Cambodia says Thai actions at border temples breach international law

PHNOM PENH, May 23, 2026 (KPT) – Cambodia has accused Thailand of violating international law and illegally occupying several ancient temple sites along their disputed border, in a diplomatic briefing attended by foreign envoys in Phnom Penh.

The Ministry of Foreign Affairs and International Cooperation said Thursday’s session was attended by representatives from 44 diplomatic missions and international organisations accredited to Cambodia.

Culture and Fine Arts Minister Phoeurng Sackona outlined Cambodia’s position on contested sites including the Tamone temple complexes, Ta Krabey Temple and Khnar Temple. She reaffirmed Cambodia’s sovereignty claims, saying Thai armed forces have occupied the sites since December 2025.

The minister also cited damage to the Preah Vihear Temple, a UNESCO World Heritage Site, and other monuments of “outstanding universal value.”

According to the ministry, Thailand has carried out activities aimed at asserting sovereignty over the sites, including religious ceremonies, visits by cabinet members, restoration works without Cambodian approval, and listing the temples in its national heritage inventory.

Cambodia further alleged that permanent structures, including large Buddha statues, had been installed at some locations.

Phnom Penh said it has lodged repeated diplomatic protests and vowed to continue opposing what it described as unlawful actions intended to create “a fait accompli on the ground.”

Sackona stressed Cambodia’s commitment to resolving border disputes peacefully, in line with international law and bilateral agreements, adding that maintaining stability between the two neighbours was vital for ASEAN unity.
