Google正式宣布，Google不想继续对Google.cn的搜索结果进行审查，并将在接下来的几周内与中国政府进行探讨，如何让Google.cn在不进行审查过滤的前提下合法地运营，如果做不到这些，Google将考虑关闭Google.cn，甚至是它的所有中国办公室。下面是全文：

Like many other well-known organizations, we face cyber attacks of varyi
ng degrees on a regular basis. In mid-December, we detected a highly sop
histicated and targeted attack on our corporate infrastructure originati
ng from China that resulted in the theft of intellectual property from G
oogle. However, it soon became clear that what at first appeared to be s
olely a security incident--albeit a significant one--was something quite
 different.

First, this attack was not just on Google. As part of our investigation
we have discovered that at least twenty other large companies from a wid
e range of businesses--including the Internet, finance, technology, medi
a and chemical sectors--have been similarly targeted. We are currently i
n the process of notifying those companies, and we are also working with
 the relevant U.S. authorities.

Second, we have evidence to suggest that a primary goal of the attackers
 was accessing the Gmail accounts of Chinese human rights activists. Bas
ed on our investigation to date we believe their attack did not achieve
that objective. Only two Gmail accounts appear to have been accessed, an
d that activity was limited to account information (such as the date the
 account was created) and subject line, rather than the content of email
s themselves.

Third, as part of this investigation but independent of the attack on Go
ogle, we have discovered that the accounts of dozens of U.S.-, China- an
d Europe-based Gmail users who are advocates of human rights in China ap
pear to have been routinely accessed by third parties. These accounts ha
ve not been accessed through any security breach at Google, but most lik
ely via phishing scams or malware placed on the users' computers.

We have already used information gained from this attack to make infrast
ructure and architectural improvements that enhance security for Google
and for our users. In terms of individual users, we would advise people
to deploy reputable anti-virus and anti-spyware programs on their comput
ers, to install patches for their operating systems and to update their
web browsers. Always be cautious when clicking on links appearing in ins
tant messages and emails, or when asked to share personal information li
ke passwords online. You can read more here about our cyber-security rec
ommendations. People wanting to learn more about these kinds of attacks
can read this U.S. government report (PDF), Nart Villeneuve's blog and t
his presentation on the GhostNet spying incident.

We have taken the unusual step of sharing information about these attack
s with a broad audience not just because of the security and human right
s implications of what we have unearthed, but also because this informat
ion goes to the heart of a much bigger global debate about freedom of sp
eech. In the last two decades, China's economic reform programs and its
citizens' entrepreneurial flair have lifted hundreds of millions of Chin
ese people out of poverty. Indeed, this great nation is at the heart of
much economic progress and development in the world today.

We launched Google.cn in January 2006 in the belief that the benefits of
 increased access to information for people in China and a more open Int
ernet outweighed our discomfort in agreeing to censor some results. At t
he time we made clear that "we will carefully monitor conditions in Chin
a, including new laws and other restrictions on our services. If we dete
rmine that we are unable to achieve the objectives outlined we will not
hesitate to reconsider our approach to China."

These attacks and the surveillance they have uncovered--combined with th
e attempts over the past year to further limit free speech on the web--h
ave led us to conclude that we should review the feasibility of our busi
ness operations in China. We have decided we are no longer willing to co
ntinue censoring our results on Google.cn, and so over the next few week
s we will be discussing with the Chinese government the basis on which w
e could operate an unfiltered search engine within the law, if at all. W
e recognize that this may well mean having to shut down Google.cn, and p
otentially our offices in China.

The decision to review our business operations in China has been incredi
bly hard, and we know that it will have potentially far-reaching consequ
ences. We want to make clear that this move was driven by our executives
 in the United States, without the knowledge or involvement of our emplo
yees in China who have worked incredibly hard to make Google.cn the succ
ess it is today. We are committed to working responsibly to resolve the
very difficult issues raised.
