BANGKOK, THAILAND - THAILAND'S prime minister said on Tuesday he would not block attempts by neighbouring Cambodia to have the disputed Preah Vihear temple complex listed as a United Nations World Heritage site.

Thailand and Cambodia have historically both laid claim to Preah Vihear, an ancient Hindu site perched high on a mountaintop on the Thai-Cambodia border.

Newly-elected Thai Prime Minister Samak Sundaravej said his government had reached an agreement with their neighbour allowing Cambodia to propose Preah Vihear temple - but not the surrounding land - as a World Heritage site.

'Cambodia confirmed that they will propose only the temple site for World Heritage status, not the surrounding area,' he added.

Thai Foreign Minister Noppadon Pattama said the communique would also stipulate that Thailand and Cambodia must jointly manage the area surrounding Preah Vihear.

The United Nations culture organisation Unesco ruled last year against granting the temple coveted World Heritage status, but recognised it as a significant international site.

Rumours swirled that Thailand had blocked Cambodia's efforts to have Preah Vihear listed, but Cambodian officials denied that and said they expected the temple would be accepted this year after they submit a management plan to the World Heritage Committee.

A dispute with Thailand in 2003 over Cambodia's Angkor Wat temple - the most significant symbol of the country's ancient Khmer empire - sparked a night of riots that saw Thailand's embassy and several Thai-owned businesses burned and looted in the Cambodian capital, Phnom Penh.

Disagreements over Preah Vihear, which sits on Cambodian soil but can only be easily accessed from Thailand, have long plagued Thai-Cambodian relations.

Former Cambodian king Norodom Sihanouk took Thailand to the World Court in 1962 over the two countries' claim to Preah Vihear. The court ruled that the temple belonged to Cambodia. -- AFP
