An anonymous reader writes: Ars takes a look at the cyberspying agreement between the U.S. and China. The article looks at what the accord does but more importantly, what it does not. "But even assuming both sides would follow the pact, the accord is tall on rhetoric and short on substance. The deal, for instance, defines the method of enforcement as requiring the two nation's to create a 'high-level joint dialogue mechanism,' according to a joint statement from Attorney General Loretta Lynch and Homeland Security chief Jeh Johnson. More important, the two superpowers make no commitment not to hack one another for intelligence-gathering purposes. That means the recent hack of the Office of Personnel Management's background investigation data—5.6 million sets of fingerprints from US federal employees, contractors and other federal job applicants—doesn't run counter to the accord. The OPM hack is believed to have originated in China and the data, as Ars has previously reported, is 'in the hands of the foreign intelligence services of China.'"
