When Christie’s announced its plans to auction off two 18th-century bronze sculptures, the Chinese flatly said "no." At the center of the dispute are two bronze sculptures, part of the late Yves Saint Laurent’s private collection of arts and antiquities. The two 18th-century pieces — fountainheads of a rabbit and a rat — disappeared when French and British Allied forces pillaged Beijing’s Old Summer Palace during the second Opium War in 1860. China says the relics are part of its cultural heritage and should be returned.
