THE UNPLEASANT TRUTH about Chinese espionage. “In the two weeks since the Lin story broke, we have still more cases of Chinese immigrants accused of spying against their adopted country on behalf of their ancestral one. . . . The most challenging part of how China spies on the United States is that Beijing’s modus operandi relies overwhelmingly on co-nationals. Chinese intelligence agencies seldom stray far from working with ethnic kin and Beijing-related spy cases here that do not involve ethnic Chinese are very much an exception. Even when non-Chinese are involved, there is usually someone tied to Beijing by ethnicity somewhere in the operation.”
