NEWARK, N.J. (AP) – U.S. Customs and Border Protection officers and Homeland Security investigators uncovered two priceless Chinese antiques in shipping containers at Port Newark last week.

Officials say the Tang Dynasty horse and rider and a prehistoric Chinese pot are estimated to be from 1,500 to 5,000 years old.

There is no word about who had shipped the antiquities and no arrests have been made.

The discovery was made on Feb. 23 and announced Thursday.

The U.S. has been working with the Chinese government to intercept the illegal trade of archaeological materials and return them to China since 2009.
