As Snowden has revealed during an interview on German TV, the spying isn't just on citizens -- industry is being watched as well, Voice of America reported. More specifically, the agency is keeping its eye on foreign industrial entities in U.S. business interests, according to RT.com.
“There is no question that the U.S. is engaged in economic spying,” Snowden says in the interview. "If an industrial giant like Siemens has something that the NSA believes would be beneficial to the national interests, not the national security, of the United States, they will go after that information and they will take it."
What the agency would do with that information once in its possession is unclear.
