As the article says, "This shouldn't surprise anyone. For years, the US and the Five Eyes have had a monopoly on spying on the Internet around the globe. Other countries want in."
Yes, but now China can check to be sure that the data they have tunneled out of the Five Eyes stores are accurate... see that's getting real intelligence information :^)
The huge difference is the NSA collects to achieve political goals. China spies for political and economic benefit. Foreign businesses are frequently targeted with the singular goals of IP theft or gaining leverage in business negotiations.
Wow. I'm always astonished by the people who think economic espionage isn't a huge part of Western intelligence services. It is.
The Americans just hide it better and it's entirely within their mandate. China couldn't care less if the world finds out. France is absolutely running wild and has been for decades. Australia has been caught planting bugs in foreign leaders offices for the sole purpose of an oil companies business deal.
