A painting by Chinese artist Sanyu fetched a record HK$42.1 ($5.4 million) at a Hong Kong auction as bidders fought for lots, betting that the worst of Asia’s art-market slump is over.

Of the 38 lots offered last week at Christie’s International’s top selection of Asian art, 34 sold, raising a combined HK$181.7 million, according to the London-based auction house.

That’s about twice the company’s presale estimate, said Kate Malin, a Christie’s spokeswoman.

The first auction devoted solely to contemporary design will take place at Christie’s in New York this autumn.

“It really is an increasingly popular market,” said Carina Villinger, design specialist of Christie’s New York. “There is a huge overlap with contemporary art. It has got to the point where we need a separate auction.

The Christie’s sale will feature items such as a polyurethane table by the London-based Iranian architect Zaha Hadid, who designed the aquatics centre for the London Olympics, estimated to raise $200,000.

Another lot will be a highly polished steel sofa by the British-born Israeli designer Ron Arad for $300,000. Arad’s work will be exhibited at the Museum of Modern Art in New York next year.That sofa is made of steel that’s polished to match the reflection of a real mirror!
