China today rejected a report suggesting it may be involved in using computer networks to spy on exiled Tibetans and foreign governments (including Malta's), accusing its authors of being possessed by "the ghost of the Cold War".

China has been repeatedly accused of using the Internet to secretly enter computer networks abroad to carry out sabotage and gather intelligence, and it has repeatedly denied such claims.

A report from the Toronto-based Munk Center for International Studies in Toronto said at least 1,295 computers in 103 countries were breached by the spying, which it said was based in China but could not be definitively linked to the government.

A spokesman for China's Foreign Ministry dismissed such claims as rumour and said his government was committed to protecting Internet security.

"Nowadays the problem is that there are some people abroad avidly concocting rumours about China's so-called Internet espionage," spokesman Qin Gang told a regular news briefing.

"There's a ghost abroad called the Cold War and a virus called the China threat," Qin continued, breaking into English-language phrases to make his meaning clear.

"People possessed by the ghost of the Cold War constantly issue this China threat virus."

Among the sites infiltrated from China were embassies, foreign ministries and government offices, especially across southeast and south Asia, and the Dalai Lama's Tibetan exile centres, the Canadian researchers said in the report released at the weekend.

The report suggests many of the computers used to control the virus appeared to be run from Hainan, where the Chinese government operates a signals intelligence centre.

But it also says it is hard to definitively prove this and that alternative explanations are possible. The whole issue of cyber-espionage is shrouded in mystery. Not just the Chinese, but the United States, Israel and Britain are known to have sophisticated electronic spy capabilities.

Whoever may be responsible, the report details a far-reaching campaign to infiltrate the computer networks of China's critics and their allies, not just among Tibetan exile groups but also Taiwan trade organisations.

"The attempts of these people to use rumours to vilify China will never succeed," said the Chinese spokesman Qin.
