Reflecting the recent nose dive in confidence in the art and antiquities markets, the International Asian Art Fair held each spring in Manhattan has been canceled. The event’s organizers said the current economic slump was the determining factor. Haughton International Fairs, the event’s organizer, said on its Web site (www.haughton.com) that the declining global economy had “strained the resources of many dealers” who had agreed to participate. The fair (which last year featured pieces from Oi Ling Antiques, above) had been scheduled for March 11 to March 15 at the Park Avenue Armory, at 67th Street.
