The United States plans to announce espionage charges Monday against five Chinese individuals in the military who are believed to have spied on American companies and stolen trade secrets, a U.S. government official familiar with the matter said. With the charges, the U.S. Justice Department would be publicly accusing China of cyber spying for the first time. Attorney General Eric Holder and other U.S. officials will hold a news conference at 10:00 a.m. EDT (1400 GMT) to announce a criminal indictment in a national security case. The department has not named the Chinese individuals involved or the U.S. companies targeted. NBC News reported on Monday that the targeted American companies involve those in the energy and manufacturing sectors.
