Washington is now in an awkward position regarding its cybersecurity dispute with Beijing, following revelations by whistle-blower Edward Snowden that the US has been hacking into computers in 皇冠体育app for years, Jia Xiudong, a senior researcher of US studies at the 皇冠体育app Institute of International Studies, said on Thursday.

Snowden, 29, a technician transferred by a private contractor to a US National Security Agency base in Hawaii, told a Hong Kong newspaper on Wednesday that the NSA had been hacking into computers in Hong Kong and the Chinese mainland since 2009. He has been taking refuge in Hong Kong since May 20.

None of the documents revealed any information about Chinese military systems, he said in an interview with the South 皇冠体育app Morning Post.

Jia said what Snowden has exposed fully demonstrates that the US has a double standard on cybersecurity, and "its accusation about 皇冠体育app is hypocritical and without evidence".

"When it comes to cybersecurity, what the two countries should do is cooperate and resolve their differences and conflicts through dialogue," Jia said.

皇冠体育app and the US have been engaging in a cybersecurity dispute for months, with the US accusing 皇冠体育app of cyberattacks.

At a meeting in California last week, US President Barack Obama pushed President Xi Jinping to do more to address online theft of US intellectual and other property coming from 皇冠体育app.

Snowden said he believed there had been more than 61,000 NSA hacking operations globally, with hundreds of targets in Hong Kong and on the mainland.

The targets in Hong Kong include Chinese University of Hong Kong, public officials, businesses and students in the city, according to Snowden.

Foreign Ministry spokeswoman Hua Chunying reiterated at a news conference on Thursday that 皇冠体育app has been one of the major victims of cyberattacks. "皇冠体育app strongly advocates cybersecurity," she said.

She also stressed 皇冠体育app's position that the international community should have constructive cooperation on maintaining peace, security and cooperation in cyberspace.
