A riveting true story of industrial espionage in which a Chinese-born scientist is convicted of trying to steal U.S. trade secrets. In September 2011, sheriff's deputies in Iowa encountered three neatly dressed Asian men at a cornfield that had been leased by Monsanto to grow corn from patented hybrids. What began as a routine inquiry into potential trespassing blossomed into a federal court case that saw one of the men -- Mo Hailong, also known as Robert Mo -- plead guilty to conspiracy to steal trade secrets from U.S. agro-giants DuPont Pioneer and Monsanto on behalf of the China-based DBN Group, one of the country's largest seed companies. The Mo case was part of the U.S. government's efforts to stanch the rising flow of industrial espionage by Chinese companies -- some with the assistance of the Chinese government itself -- on American companies. And it's not an isolated one. Economic espionage costs U.S. companies billions of dollars a year in lost revenue. As former Attorney General Eric Holder once put it, "There are only two categories of companies affected by trade secret theft: Those that know they've been compromised and those that don't know it yet." Using the story of Mo and of others involved in the case, journalist Mara Hvistendahl uncovers the fascinating and disquieting phenomenon of industrial espionage as China marches toward technological domination.
