("Spy vs. Spy," by deviantart user Zarious)

“Oppressive” and anti-western as Chinese ideologies are, the Chinese market is too lucrative for foreign companies to boycott China.  Though transnational corporations are subjected to the same self-censorship regulations as Chinese companies, several U.S. corporations have entered the Chinese market since China’s Great Firewall was erected, and many others, notably the social-networking giant Facebook, are looking to follow suit.  These companies rightfully contend that they must comply with Chinese laws when while operating the Chinese market, even if this violates U.S. standards of freedom of speech, or foreign perceptions how China should govern its own citizens.  Furthermore, to justify their foray into or stronghold in the profitable Chinese market, they often argue that some information is better than none at all—that only by respecting the Chinese government’s demands can they bring more quality information into the average Chinese citizen’s reach [1].

In this article we examine the case studies of Yahoo!, Microsoft, and Google to understand corporations’ motivation and general approach when entering China.  We will next look into the U.S. government’s reaction and attempted regulations.  Finally, we will touch on some recommendations for more effective regulation in the future.


Yahoo! was the first major U.S. Internet company to enter the Chinese market, rolling out a Chinese language search engine and a Beijing office in 1999.  Three years later, in 2002, it signed the “Public Pledge for Self-Discipline and Professional Ethics for Chinese Internet Industry,” “which requires Yahoo! to “carry forward the rich cultural tradition of the Chinese nation and the ethical norms of the socialist cultural civilization,” to protect China’s state security, and refrain from publishing information that may disrupt social stability.  Yahoo! remains to this date the only western company known to have signed the pledge [2].

Under this pledge, Yahoo! provided the Chinese government with user information that eventually led to the arrest and conviction of journalist Shi Tao in April 2005, when he used his Yahoo! email account to send communications to a pro-democracy website abroad.  Many cases of a similar nature, though perhaps less severe, have been reported since [3].


Microsoft joined Yahoo! in China when it launched MSN China in 2005, and censored as requested by the Chinese government.  Though Microsoft endured attacks from the very beginning for censoring, its most notable crisis occurred when it shut down Zhao Jing’s blog on MSN Spaces—Microsoft’s blogging platform.  Zhao Jing, who also wrote under the pseudonym Michael Anti, was one of China’s most read, out-spoken bloggers at the time.  Angry responses broke out in the west, and Microsoft’s own in-house blogger Robert Scoble offered to lend Michael Anti his own site: “Guys over at MSN: sorry, I don’t agree with your being used as a state-run thug,” he said. “It’s one thing to pull a list of words out of a blog using an algorithm. It’s another thing to become an agent of a government and censor an entire blogger’s work,” wrote Scoble in his correspondence with CNN’s Rebecca Mackinnon [4].

Due to the heavy criticism, in January 2006 Microsoft altered its blog censorship policy in China, committing only to “remov[ing] access to blog content when it receives a legally binding notice from the government indicating that the material violates local laws” [5].  In addition, Microsoft stated that it would remove said content only in the relevant country issuing the notice, and promised to inform users why specific content is blocked.  Today Microsoft supports a call for action to loosen information control in China.


The launch of marked Google’s official entry into the Chinese market in January 2006.  Unlike Yahoo! and Microsoft, Google spent a public year “soul-searching” before the launch, and from the very beginning claimed that it did not plan to disclose to the government any information on those who search for blocked content.  Google was also the first and only to promise to inform users that certain searched content has been restricted under governmental regulation [6].  Still many considered Google’s actions a dark contradiction to its famous “Don’t Be Evil” motto.  Even more ironically, how can Google agree to China’s demands of censorship when it denies the U.S. government access to similar user information?  Google’s Chinese site remained under criticism, and many Internet users took it upon themselves to inform others of Google’s “evil.”  This YouTube video, for example, compared search results for “Tiananmen Massacre” on Google UK and Google China, sparking a flurry of crude yet often relevant responses from other YouTube users.

The struggle continued until January 12, 2010, when several of Google’s servers were apparently hacked to access information on Chinese dissidents.  The Foreign Correspondents Club of China independently confirmed “eight cases in which journalists based in China and Taiwan had their accounts hacked in recent weeks.”.  Google then announced plans to negotiation an unfiltered search engine with China.  When negotiations failed in March 2010, Google automatically redirected all of search traffic to, which is based in Hong Kong and thereby no longer under Chinese jurisdiction [7].  Not much changed, however, as the Chinese government quickly moved to block user access to, and the firewall continued to filter results when Chinese users search through still redirects to today.

U.S. Government

The U.S. is a huge technology hub, and as many of the Internet/technology corporations in China today are U.S. based, Google, Yahoo! and Microsoft being prominent examples.  Given this background, and give the public response to Google’s Yahoo!, and Microsoft’s behavior in China, the U.S. government takes a natural interest in U.S. corporate accountability in the Chinese market.  In 2006, the U.S. House of Representatives held a joint committee at which representatives from top U.S. companies must testify about their business practices in China.  Soon after, Republican Rep. Christopher Smith proposed the Global Online Freedom Act of 2006, and later the Global Online Freedom Act of 2007 [8].  These acts hope to promote freedom by prohibiting U.S. companies from censorship.  Idealistic as they are, they did not pass: imposing U.S. ideologies and regulations upon companies in foreign land seemed neither appropriate nor effective.

Into the Future

Given the multinational nature of many large companies today, no nation’s regulation will suffice to ensure freedom to the entire Internet.  Either an international regulatory agency must take on this burden, or we must create an industry-wide standard of conduct to navigate different governments and ideologies.  The latter, more flexible and easier to achieve, may be an effective stepping-stone towards the former, more official code conduct.

Within the Wall : Perceptions of Censorship by the Average Chinese Netizen Thu, 02 Jun 2011 05:24:04 +0000 atlai

The advent of the Great Firewall in China has undoubtedly huge implications for everyone involved – but while plenty has been said about the firewall itself, what of the citizens in China? How have they reacted against the existence of the Firewall? How has the Great Firewall affected cyberactivists and the average citizen?

The first thing that must be addressed is the conception of the Great Firewall through the metaphor of the Great Firewall itself. The image of that the phrase  “The Great Firewall” is wonderfully evocative – that of  a towering edifice, huge and shimmering like a cross between The Matrix and Guantanamo Bay. The idea in many American minds is of a wall that is both obvious  to everyone it constrains and constantly tested. This is true in some sense, but in another it overstates the effect that the Great Firewall has had on people in China.

In a large part, discourse about ‘helping the Chinese break free’ and ‘web activism’ are rooted in the rhetoric of the Cold War and continuing Western ethno-centrism. Particularly telling is a response by Liu Kang, noting that ““tales of China’s political repression and terror have more to do with the political, ideological, and commercial objectives of the Western media than with what really happens in China today.”[1]

The number of internet users in China, as of 2008, counts in at roughly 253 million netizens, about 40 million more than the amount of internet-users in the United States.[2] Of these, roughly 25 percent uses proxies to get around government firewalls, though studies have shown that during the SARS outbreak that percentage jumped to over 50 percent[3]. The image of tech-savvy netizens as being in the minority in China has to be discarded – instead it has to be considered that Chinese citizens are not unable to breach China’s firewall. They are uninterested in testing the limits of the firewall.

A recent study carried out in 2007 show that over 50 percent of internet users in China believe that it was “very necessary” to control the internet, while 30 percent believed that it was “necessary” to control the internet. Only 5 percent of respondents said that it was “unnecessary” or “very unnecessary” to control the internet. Even more relevant, however, is that 41 percent of respondents believe that political content should be controlled.[4]

However, this doesn’t mean that they are powerless or brainwashed in the face of the state and corporations. Rather, it seems that the term control does not mean out and out censorship.

The internet has been used to uncover government lies and corruption, such as an explosion at a school in Jiangxi. Originally the government explained the problem as the work of a “madman”, but through electronic bulletin boards the cover-up was exposed and an official apology (rare for the Chiense government) was issued.

Another example would be that of a rural-urban work migrant Sun Zhigang, who died ‘of a heart attack’ while in police custody. Netizens eventually uncovered the fact that Sun was beaten to death, and outrage and activism over this fact managed to spur changes in government policy – in particular the transformation of migrant detention centers, as well as the requirement for works such as Sun Zhigang to carry a work permit on their selves at all times.[5]

The Lang Xianping Cyclone : Net-based Activism

The Liang Xianping Cyclone is an event in August of 2004 where Lang Xianping published a scathing indictment of multiple privately-owned businesses that, he claimed, were buying out state assets illegally and, thus, privatizing what traditionally belong to the public. He made his case in multiple public chatrooms and eventually set up his own website to discuss the issue, with over 40,000 people reading his opinions in the end.

The response was both huge and immediate. Criticisms and counter-criticisms of Liang’s opinions were formed and posted on the web and off the web. Leading economists formally petitioned the government to investigate privatization in China. Eventually the scope of the argument widened when a worker, recently laid-off, posted online questioning why the discussion was so academic, ignoring the voices of the people on the ground.

At the same time as these questions were being discussed, a strike occurred over the buyout of a state-owned factory allegedly worth 200 million for 20 million by a private company. These events were linked back to the debate started by Liang Xianping and further debate questioned the rights of the government to shut down protest [6].

The furor over Chinese networks also mirror another emerging democratic phenomenon – that of the “Human Flesh Search Engine” – a prime example of mobilized social justice on the web.

Human Flesh Search Engines : Web-Crowds and Crowd Justice

The term “Human Flesh Search Engine” refers to organized groups of Chinese netizens who engage in, “a form of online vigilante justice in which Internet users hunt down and punish people who have attracted their wrath”[7]. When an injustice occurs and arouses the ire of the Human Flesh Search Engine, woe betide the person found wanting.

One common example is that of the “Kitten Killer” – a woman who filmed herself stomping a live kitten to death. As soon as it was posted on online Chinese forums, groups of Chinese users began to try to puzzle out the identity of the woman in the video. Within days an originating website, crushworld, had been found and a Distributed Denial of Service attack launched. Six days later the identity, job, and address of the woman had been found, and a furious cyber-public had both her and her cameraman fired from their jobs[8].

The emergence of Human Flesh Search Engines is very much the emergence of democratic action in Chinese webspace. Even though the Great Firewall still very much exists, it has only shifted the ways in which the public can organize themselves and obtain information. These search engines allow the average citizen to enact social justice and gain leverage over other citizens in the real world. The activities of people participating in the Human Flesh Search engine is not heavily monitored by the government either – China has moved on from the image of totalitarian control, and censors generally allow activity like this to go unfettered[9].

In contrast to the US, where large media topics are commonly ‘broken’ by the new corporations, many Chinese citizens get their news from anonymous online forums, possibly due to the heavy regulation of state media. The well-educated portion of China’s demographic tend to be the ones frequenting online forums, and it is these citizens that are mobilizing against government and social injustices[10]. By engaging in Human Flesh Searches and mobilizing public opinion against public officials many netizens are able to get them dismissed so the government doesn’t lose face. While the relationship is less than an openly acknowledged one, it’s one that is heady to a citizen whose impact on official governance may have felt limited at the best of times.


The power of Chinese citizens cannot be underestimated, and the agency  the average citizen has as a result of the internet, no matter how censored it may be, cannot be underestimated. In general rhetoric the image of the Chinese citizen is one of subservience to all-powerful and overwhelming government oppression. In truth, as always, the situation is a bit more complicated. With the ability of the internet to stir up outrage and uncover information, as well as connect disconnected parties, the Chinese citizen can still speak out and effect change against their government.

The Great Firewall of China: Background Wed, 01 Jun 2011 07:52:19 +0000 pingp The Great Firewall of China, also formally known as the Golden Shield Project, is the Chinese government’s internet censorship and surveillance project.  Initiated, developed, and operated by the Ministry of Public Security (MPS), the project is one of the most controversial subjects in the world.  While many people of the Western world treat the project as a human right violation, some countries are actually adopting China’s model.  Some people think that the issue is interesting because the Chinese economy benefits tremendously from the Internet, but the Internet, in turn, is interfering with its political stability.  Other people think that it is just a matter of time until Chinese communism collapses.  On this website, we will provide a thorough examination of historical and technical aspects of the Great Firewall of China.

China’s Great Dilemma

The Internet came to China in 1994, under the presidency of Jiang Zemin.  His decision to develop the Internet in China was heavily influenced by Alvin Toffler’s “third wave” theory, which claims that the world is moving away from the Industrial Age (second wave) to the Information Age (third wave).  For China to compete with other countries, it is thus imperative that the Internet be accessible in the country.  The idea of bringing in new technology to improve China’s competitive edge, however, is not new.  Since 1979, Deng Xiaoping enacted the Open Door policy to bring in Western knowledge and open the country to foreign trade and investment.

After the Open Door policy was implemented, China has struggled to strike a balance between “opening up” to the Western world and keeping its people away from the Western ideology.  Deng Xinaoping once said that “if you open the window for fresh air, you have to expect some flies to blow in.”  In order to keep these “flies” away, the Ministry of Public Security thus initiated the Golden Shield Project in 2000.  This particular project poses one of the most ironic dilemmas in modern history.  On one hand, the Chinese government desires to make use of the information technology that comes with the Internet to drive its blooming economy.  On the other hand, the Internet inherently encourages diversity of ideas, and is a tool for democratizing society.  In other words, while the Internet is important to China’s economy, its very existence also undermines the political stability of the country.  China is constantly seeking to strike the balance between these two ends.


The Golden Shield Project

Just as the Chinese government had expected, the number of internet users in China soared from nearly 0 percent in 1994, when the Internet was first introduced to the society, to 28.8 percent in 2009.  While the amount of information over the last fifteen years was increased exponentially, the government is losing control the spread and availability of information.  The Chinese government, however, is determined to control online content and its citizens with regard to the kinds of information to which they have accessed.  MPS, the branch of the government that is deals with this issue, immediately took action by launching the Golden Shield Project.

Although MPS has been developing the Golden Shield Project sine the 1990s, the project made its first public appearance in 2000, during the Trade Show held in Beijing.  Security China 2000, one of the showcases in the Trade Show, became the foundation of the Golden Shield Project.  According to a report by Greg Walton, Security China 2000 aimed to promote “the adoption of advanced information and communication technology to strengthen central police control, responsiveness, and crime combating capacity, so as to improve the efficiency and effectiveness of police work.”  The government initially envisioned the Golden Shield Project to be a comprehensive database-driven surveillance system that could access every citizen’s record as well as link national, regional, and local security together.

The unexpected speed of Internet expansion in China, however, necessitated various adjustments to the initial vision of the Golden Shield Project.  The liberalization of the telecommunication sector bought about rapid changes in technology.  This greatly reduced the project’s potential to be the system that links information from all levels, local to national.  As a result of reassessment and evaluation, the Golden Shield Project now focuses on content-filtering firewalls on individuals instead – the direction that eventually earned the nickname the Great Firewall of China.  In other words, the project shifted from “generalized content control at the gateway level to individual surveillance of users at the edge of the network.”

In order to develop necessary the technology for the project, the Chinese government hired teams of engineers and collaborated with many research institutes and technology providers both within the country and outside.  Tsinghua University and Nortel Networks, one of the largest Canadian telecommunication technology providers, were two organizations that spearheaded the research.  The main objective of this collaboration was to develop China’s networking capability.  Nortel Networks, however, was not the only Western corporation that helped China develop its surveillance technology.  Walton reported that Motorola provided wireless communication devices for China’s traffic police; Sun Microsystems linked all 33 provincial police departments through computer networks; and Cisco Systems provided China with routers and firewalls in the network.

Today, with its most sophisticated internet censorship program, China even exports its technology to other countries such as Cuba, Zimbabwe, and Belarus.  To help you get a glimpse of what is China current censorship and firewall system is like (although we will cover the technical details in later section), we provide this short video from YouTube:

A Culture of Self Censorship

What makes the Great Firewall of China so effective (and controversial) is not only its complex technology but also the culture that the system engenders – a culture of self-censorship.  The Chinese government mandates that companies be responsible for their public content.  In other words, it is the job of these companies to make sure that their online portals do not contain any prohibited topics or obscenities.  Leading online news media in China, such as,, Chinanews, and obediently follow the government’s decree, pledging that they “will make the Internet a vital publisher of scientific theories… maintain social stability, and promote the building of a socialist harmonious society.”

Transnational Internet corporations such as Google, Yahoo!, and Microsoft are also subjected to self-censorship regulations.  Although censorship is very much against Western ideology, the size of the Chinese market is too profitable for the companies to bypass these opportunities.  However, self-censorship does attract criticism in the Western hemisphere.  For example, Google’s decision to censor some of its content to please the Chinese government is currently one of the most discussed topics in the Western media (we will also cover this in greater detail later).

The figure above shows an error message from MSN Spaces Censorship (Microsoft), which reads that “this item contains forbidden language: Please remove the forbidden language from this item.”

The above finding from an empirical study by OpenNet Initiative displays the most commonly censored words or phrases.

The Great Firewall: a technical perspective Mon, 30 May 2011 02:46:26 +0000 martyhu

How exactly does the Great Firewall Work? In this post, we’ll discuss the technical details of China’s firewall infrastructure. You’ll get to understand of some of the technology China employs as well as it’s limitations.

Laptop user in China

First, we’ll clarify some terminology and background on how the internet works. You’ll need to understand this to get through the rest of this article. If you’re already internet and tech savvy, feel free to skip ahead.

Quick Layman’s Guide to How the Internet Works:

The internet is basically a huge pile of computers. Each time you go to your favorite website (ie., you’re establishing a connection with that computer. The remote computer sends you some data, which you can view via your browser. You can keep the connection with the computer open as long as you need data from it.

The dirty secret of the internet is that when you go to your favorite website, you may not be going to the same computer. Why’s that? Well, depending on where it might be more convenient for you to go to a computer that’s closer to where you are. Just as if you were shopping for your groceries, you would go to a different convenience store depending on where you lived. So really, the grocery store is better identified by it’s address, rather than it’s name. There are many Ralph’s all over the country, but there is only one a block away from your home.

Computers are much the same way. The physical location of your favorite grocery store in the computer world is known as an IP address – a unique identifying number for every machine on the internet. Most addresses are typically IPv4, which just means that they are 32 bits in length. Here’s a typical IP address.

IP Address

From reading this, you might notice that the number seems a bit random. If you did, you’d be exactly right – IP addresses are very hard to remember. So instead of using IP addresses to navigate to the computers we want, we tend to use human readable domain names, like and The side effect to doing this is that each time we want to go to the domain name we remember we must go look up the IP address before we can connect and fetch the data we want. The machine for this is called a name server.


Each of the beige boxes in the above diagram is a name server. How name servers work, in essence, is as follows:

  1. Client gives the name server the name they remember. In this diagram, it’s
  2. Name server goes and asks some other authority name servers where to go. In the diagram, this process is labelled 1, 2, and 3.
  3. Name server returns the IP address. In this diagram, it’s

The key piece to note is that every name server must depend on an authority name server, and trust falls completely on the authority name server. This becomes an interesting situation in the Chinese firewall, where the Chinese government controls all of the national authority name servers. We’ll talk more about this in a bit.

Technical Walk-through on how the Great Firewall works:

The Great Firewall uses three distinct types of methods to block access to websites in China. They are as follows:

  1. IP Blocking
  2. IP address Misdirection
  3. Data filtering

We’ll address each of them in turn.

IP Blocking

In this method, access to a certain IP address is refused connectivity by the Chinese firewall. This is the equivalent of preventing the user from gaining any sort of access to the remote computer, since the firewall intercepts all of the data sent and received by computers within the network.

Example: -> blocked

In the above example, maps to a known IP address (e.g so any connection made to that location is disconnected by the firewall.

IP address Misdirection

From our primer on name servers, we learned that the internet must basically trust all authoritative name servers to give it the correct IP addresses for a given name. However, in the case of the Great Firewall, the Chinese controls the majority of the internet presence and many of the authoritative name servers. By exploiting a flaw in the naming system, the government can redirect a given domain name to whichever actual web site it would rather have the people see. This technique is often called URL hijacking.

Example: -> (

In the above example, note that itself is based in the United States. Since is the actual IP address, it acts as the final arbiter as to what it’s own IP address is. However, any user from within China trying to reach will have his/her data intercepted by the Great Firewall as the request leaves China. Then, before (which is located on the other side of the world) even sees the request, the Chinese government will issue a fake response to the original request solicitor. The naming system, which is built entirely on trust, is designed to accept this response without further asking and it goes to the fake website.

Data Filtering

The Chinese government will also examine the content of the URL that a request solicitor initiates a request with as well as the data they send inside of that request. These techniques are called URL filtering and packet filtering respectively.

Example 1: -> blocked

In the above example, a user initiates a Google search for “Tienanmen Square”. This creates a request URL with “tiananmen+square” in the URL, which is intercepted by the Chinese government and dropped. This is an example of URL filtering.

Example 2: -> blocked

In this case, the user navigates to a URL that doesn’t have any obviously discernible characteristic that ought to become blocked. However, the website itself contains information about Falun Gong: a system of beliefs and religious movement in China upon, which the government has relentlessly cracked down and prosecuted. The firewall, intercepting such information, would identify Falun Gong in the data and block further transmission.

This concludes the short primer on the technical aspects regarding the Great Wall. Feel free to comment and give your opinion.
