A planned Paris sale of two Qing Dynasty bronzes from the late French designer Yves Saint Laurent’s art collection is raising the ire of patriots in China who say they may sue auction house Christie’s International.

Liu Yang, who heads 67 volunteer lawyers, said the group is preparing a lawsuit to block the February sale of two animal- head sculptures -- a rabbit and a rat. They are among 700 works in the Yves Saint Laurent and Pierre Berge Collection expected to raise as much as 300 million euros ($389 million), according to a Christie’s statement from September. The proceeds will help set up a foundation for AIDS research.

“For each and every item in this collection there is a clear legal title,” Christie’s said in a statement e-mailed today in response to inquiries from Bloomberg News. “We strictly adhere to any and all local and international laws.”

Any lawsuit would be filed in the French courts, Liu said. The lawyers seek to block the sale first and ultimately to repatriate the items.

The 1995 United Nations Unidroit Convention limits claims on stolen cultural artifacts to within 50 years of their theft.

All the bronze heads are among 12 zodiac animals from a water-clock fountain in Yuanmingyuan, or the Imperial Summer Palace. The palace was set ablaze and its treasures plundered and scattered by British and French troops in October 1860.

Sale of a tiger head from the same fountain in 2000 by Christie’s rival Sotheby’s sparked protests in Hong Kong initiated by the city’s lawmakers. The horse head was offered by Sotheby’s in September 2007, privately bought by Macau billionaire Stanley Ho for $8.9 million and donated to China.

Boar, Monkey, Ox

In 2003, Ho bought the fountain’s boar head at a private sale and donated it to Beijing’s Poly Museum, an arm of the People’s Liberation Army. Poly Museum also has the monkey and ox. Whereabouts of the others are unknown.

“These items belong to China and should return to us,” said Liu, in a phone interview. “Prices of these items have soared beyond the reach of civilians and governments.”

The State Administration of Cultural Heritage declined to comment. In a November interview that ran on Xinhua News Service’s Web Site, Cultural Heritage Administration’s head of museums, Song Xinchao, said the sale of the two bronze heads violates international laws and China firmly opposes the auction.

China will try to repatriate lost treasures “through legal channels,” Song had said, without giving details.
