Cambodian Prime Minister Hun Sen has requested his Thai counterpart Gen. Prayuth Chan-ocha to allow Cambodian experts to inspect a stash of antiquities seized last month from a disgraced senior Thai police official after hearing that the treasure trove may include a number of ancient Khmer sculptures, a senior official said Saturday.

"During a meeting with Gen. Prayuth on Friday, Prime Minister Hun Sen asked his Thai counterpart to allow Cambodian archaeologists to inspect the recently seized artifacts and requested the Thai side to loosen conditions because Thailand always demands 100 percent of evidence to claim any artifacts," Kao Kim Hourn, minister attached to the Cambodian prime minister, told reporters at Phnom Penh International Airport after Hun Sen returned from Thailand.

In response, Gen. Prayuth said Thailand would return any of the seized artifacts to Cambodia if the country had about 70 or 80 percent of the evidence to prove that the artifacts were stolen from Cambodia, he said.

Last month, Thai police confiscated the antiquities in a sweeping raid of properties owned by Lieutenant General Pongpat Chayaphan, a former commissioner of the Thai police's Central Investigation Bureau.

In a series of raids, police discovered underground vaults storing assets worth more than 60 million US dollars, including about 50 historical artifacts worth some 1.52 million US dollars, according to a report in The Nation newspaper of Thailand.

The items recovered from Pongpat's estate date back to ancient Khmer, Lao, Myanmar, Ayutthaya and Rattanakosin kingdoms, the newspaper said, adding that among the seized items were 13 deities and Buddha images built in Khmer style.

Hun Sen was in Thailand to attend the fifth Greater Mekong Subregion Summit and met with Gen. Prayuth on the sidelines of the summit.
