On Thursday, China accused US intelligence agents of hacking into a government-funded university and gain control of parts of China's telecommunications network.
The National Security Agency (NSA) had gained remote access through an email phishing attack on Northwestern Polytechnical University, according to the Global Times.
The alleged hackers made off with network equipment, administrative passwords, file-transfer protocols and other sensitive data.
China claims that the NSA has collected more than 140 gigabytes of data from over 10,000 cyber attacks in recent years.
The US blames China for widespread industrial espionage on American companies, in addition to national security-related operations.
