The United States has started a trade war with China, and art is caught in the cross-fire.

The administration announced this month that President Trump had proposed duties as high as 25 percent on $200 billion worth of imported Chinese goods “to encourage China to change its harmful policies.” The proposed tariffs, initially set at 10 percent, followed two earlier rounds of penalties.

The latest list of targeted Chinese goods ran to 205 pages. It included sand blasting machines; eels, fresh or chilled (excluding fillets); hats; and, at the bottom of the last page, paintings and drawings executed entirely by hand, original sculptures, and antiques more than 100 years old.

The tariffs would apply to all artworks that originated in China, regardless of how they entered the United States. That means American buyers could be required to pay 25 percent more for a Ming dynasty bowl sold by a British owner at an auction in New York, as well as for a painting by a young Beijing-based artist at a gallery in Hong Kong.

The announcement has caused outrage in the art world.

James Lally, the founder of J.J. Lally & Co., a dealer based in New York that specializes in Asian art, said that the proposed tariffs were “a matter of great concern” to museums, collectors, curators and dealers worldwide.
