If international legal authorities and American civil courts agree, the law could establish 1925, rather than 1993, as the dividing point after which Cambodian artifacts taken without government permits can be treated as stolen property. Cambodia would still have to prove that the statue was looted after 1925, “a high burden but not an impossible one,” according to Mr. Bogdanos, who agrees the 1925 law “appears to be valid.”

"Looters are reducing countless ancient sites to rubble in their search for buried treasures to sell on the international market. The trafficking of these and other stolen cultural objects has developed into a criminal industry that spans the globe. For numerous reasons, the small Southeast Asian nation of Cambodia presents an opportunity to ground this illicit trade in reality. This paper supplements previous studies that have detailed the pillaging of the country’s archaeological sites, and aims to better comprehend the trafficking of its artifacts, through an investigation of their final destination: the international art market. Of course, the global market for Cambodian art is wide, but Sotheby’s Auction House provides an excellent sample. For over 20 years, its Department of Indian and Southeast Asian Art in New York City has held regular sales of Cambodian antiquities, which have been well published in print catalogues and on the web. These records indicate that Sotheby’s has placed 377 Khmer pieces on the block since 1988—when those auctions began—and 2010. An analysis of these sales presents two major findings. Seventy-one percent of the antiquities had no published provenance, or ownership history, meaning they could not be traced to previous collections, exhibitions, sales, or publications. Most of the provenances were weak, such as anonymous private collections, or even prior Sotheby’s sales. None established that any of the artifacts had entered the market legally, that is, that they initially came from archaeological excavations, colonial collections, or the Cambodian state and its institutions. While these statistics are alarming, in and of themselves, fluctuations in the sale of the unprovenanced pieces can also be linked to events that would affect the number of looted antiquities exiting Cambodia and entering the United States. This correlation suggests an illegal origin for much of the Khmer material put on the auction block by Sotheby’s."

"Sotheby’s has repeatedly been caught auctioning stolen art and looted antiquities, including pieces from Cambodia. For example, Sotheby’s repatriated two sandstone heads and a statuette to Cambodia after they were published by Looting in Angkor: One Hundred Missing Objects, a 1993 report of UNESCO’s International Council of Museums (ICOM), which pleaded for the return of 100 valuable antiquities stolen from the Conservation d’Angkor in the 1980s and early 1990s. In his exposé Sotheby’s: The Inside Story (1997), journalist Peter Watson uncovered that sculptures from Angkor Wat had been smuggled into Sotheby’s London offices disguised as “dolls” and “stone torsos,” on at least two separate occasions."
