At least 10 million Chinese artifacts are scattered overseas. Yet a tax on reclaimed items remains the biggest obstacle separating China's domestic market from antiques lost overseas.

Cultural relics reclamation has been a focus of concern in the Chinese art market in recent years. In the domestic art auction market, more than 60 percent of the auction items are reclaimed cultural relics. Meanwhile, Chinese collectors and some private entrepreneurs are digging deeply into their pockets to buy cultural relics from abroad.

More than 100,000 Chinese artifacts were successfully reclaimed since 1992, including around 30 collection highlights in the National Museum, according to Ou Shuying, deputy secretary-general of the China Association of Auctioneers. But since 2011, those bringing artwork into China through the Custom's office are required to pay a 30 percent tax on the value of the artwork, making the procedure less attractive.

"Collectors in the country as well as auction companies abroad don't accept such a high cost. In that case, tax is the biggest barrier for us obviously," Ou said in a recent interview.

Some auction companies tried to trade or auction in the tax-free zone in China. But according to Gan Xuejun, head of the China Association of Auctioneers, artifacts can be kept in the tax-free zone for six months at most, with a cash deposit.

"Even if the artifacts can enter the country through free trade zones, it cannot be considered a real sense of going home," Gan said.

Xu Chen, director of the Public Economy Department at the University Of International Business and Economics (UIBE), also pointed out that how to trade and display the reclaimed cultural relics in the domestic market, instead of in the Bonded Area, is a very difficult problem. Right now, many collectors prefer to keep their artifacts brought from other countries in Hong Kong to avoid the tax.
