Google's Chinese web site has been flooded with queries about the 1989 crackdown on protesters in Beijing's Tianmen Square since it said last week it will no longer censor search results.

Queries for ''Truth of Tiananmen'' surged at the second- fastest pace for any search item on  Google.cn as of 9 am on 18 January, according to the company's data on web site traffic. Data related to the crackdown is strictly controlled by Chinese authorities. (See: Google denies media reports of shutting China operations, claims business "as usual")

The searches serve to highlight the growing conflict between Chinese government and a growing population of internet users demanding greater access to information. Hundreds of supporters converged on Google's offices last week in support of the company even as it said it may wind up its China operations.  The company said today it was in talks with the government and continues to censor its China site.

Google said last week it had discovered its network had been targeted by China based hackers who attempted to access the accounts of human rights activists using its Gmail e-mail service.

According to Isaac Mao,a fellow at Harvard University's Berkman Center for Internet & Society, the sudden surge in searches for Tiananmen related topics showed that users had been trying to work out whether Google had dropped censorship altogether. He added that subjects like  Tiananmen were good acid-tests.

China, with 384 million web users at the end of 2009 is the  world's largest Internet market, according to the China Internet Network Information Center, a government agency that registers online domain names. It had only 110 million users four years ago when Google started its mainland China site.

Meanwhile the company is investigating whether the attack may have been faciltated  by one or more of its employees.

Reuters citing unidentified sources familiar with the situation, said the attack had targeted people who had access to specific parts of Google networks may have been pulled off with connivance of people working in Google China's office. 

Citing unidentified security analysts, Reuters reports that the malicious software (malware) used in the Google attack was a modification of a trojan named  Hydraq.

 A trojan, once it infects a computer, allows someone unauthorised access and they say the sophistication lay in knowing whom to attack, not the malware itself. 

According to local media which cited unnamed sources, Google China employees had been denied access to internal networks after 13 January, which some staff were sent on leave and others transferred to different offices of Google's Asia Pacific operations.

Meanwhile, Google has denied rumours it has already decided to shut down its China offices. On Monday, it said it contacted  the Chinese government last week after the announcement and it would have talks with the authorities in the coming days.

It is also in the process of scanning its internal networks following the mid-December attacks.

China on its part has sought to downplay Google's threat to leave and said that there were many ways to resolve the issue, maintaining however, that all foreign companies including Google would have to abide by Chinese laws.
