Great Firewall of China and its importance for europeean companies

W4 | W4 / March 7, 2024

The Great Firewall of China is a technical infrastructure. This technology enables the government to slow down internet speed from other countries and restrict numerous websites commonly used in the West.

In other words, the Great Firewall of China (GFW) has significant implications for businesses operating or planning to enter the Chinese market. The GFW manages access to foreign websites and services, including Google, Facebook, Twitter, and many others. While this presents many challenges for businesses trying to expand their business and tap into the vast Chinese market, there are also opportunities.

In this article, we will walk through the good and the bad aspects of the great Chinese firewall and give you a better understanding of what marketing in China means. You will be better equipped to adapt your business strategy to gain customers in China and increase your digital presence in this ever-expanding market.

Key Takeaways

  • The 'Great Firewall of China' is a complex system to restrict access to specific foreign internet content.

  • The firewall utilizes methods such as IP address blocking, DNS filtering, and deep packet inspection to ensure effective control over the digital space.

  • The internet restrictions imposed by the 'Great Firewall' significantly impact international business relationships. However, there are methods and technologies such as VPNs and reverse proxies that can be used to circumvent these restrictions.

How does the Great Firewall of China Work?

The answer is multi-faceted, as the GFC is a complex system that combines technology and legislation, and which employs a variety of methods. Furthermore, the GFW is constantly evolving, and it employs a multi-layered approach to maintain control over internet access within the country. Here's a breakdown of how it works:

Blocking Techniques:

  • IP Blocking: The GFW blocks connections to specific IP addresses associated with banned websites.
  • URL Filtering: It analyzes website addresses (URLs) and their content for blacklisted keywords.
  • DNS Manipulation: It can tamper with the Domain Name System (DNS), which translates website names into IP addresses. 
  • Deep Packet Inspection: This advanced technique inspects the data packets flowing through the network to identify and block banned content.

Thwarting Circumvention

  • VPN Blocking:The GFW tries to detect and block Virtual Private Networks (VPNs) that users might employ to bypass restrictions.

The overall effect is limited access to foreign information sources, restricted access to certain social media platforms and a slowed down cross-border internet traffic.

Impact of the Great Firewall on Internet Users and Companies


How does the "Great Firewall" impact the lives of people and businesses in China? On one hand, the "Great Firewall" restricts access to a variety of foreign websites and services. On the other hand, a parallel digital economy in China, with alternative platforms and services offering similar functions to those used in the West, rose.

Challenges Businesses encounter when faced with the Great Firewall of China

Handling legal guidelines can already be a significant challenge for businesses, requiring meticulous attention to detail and a thorough understanding of complex regulatory frameworks. However, when it comes to dealing with the Great Firewall of China (GFW), the level of complexity and the sheer scope of compliance demands create an even more formidable undertaking.

This digital barrier that restricts internet access requires a nuanced strategy for companies to ensure their digital presence is in line with these strict restrictions.

The CFW often extends beyond the digital realm and encompasses a variety of industries and sectors. The complicated web of regulations covers everything from manufacturing and trade to data protection and foreign investment. You therefore need a deep understanding of local laws, cultural nuances, and political dynamics.

Let’s explore some challenges your business might encounter when faced with the Great Firewall of China in detail.

1/ Limited Access to Information and Resources

An example of this limitation is the use of HubSpot. While many companies leverage the ecosystem for all its potential, HubSpot is not as easily accessible in China. HubSpot relies on various external tools and data sources to provide its services, and these tools and sources may be blocked by the GFW. This can limit the effectiveness of HubSpot's features, such as marketing automation, sales CRM, and customer support tools.

2/ Communication and collaboration obstacles

The GFW blocks popular communication tools like certain email providers and video conferencing platforms commonly used by businesses for collaboration and communication. This can make it difficult to stay in touch with colleagues, clients, and partners..

3/ Adapting to local regulations and requirements

All businesses in the Chinese market must comply with China's internet regulations. This can be time-consuming and complex, especially for businesses unfamiliar with China's regulatory landscape.


Embracing the philosophy that when one door closes, another one opens, prompts us to explore strategies for your business to not just overcome the Great Firewall of China but also tap into the myriad opportunities that lie beyond these digital barriers.

Firstly, consider the power of localized content. Crafting content that resonates with the Chinese audience, aligns with local values, and complies with regulatory requirements is key. By tailoring your messaging and utilizing platforms that are compatible with the Great Firewall, you can effectively reach and engage your target audience.

Additionally, leveraging virtual private networks (VPNs) and other secure network solutions can provide a workaround for accessing blocked sites and services. This enables your business to maintain a seamless online presence.

In essence, by approaching the challenges posed by the Great Firewall of China as opportunities for creative adaptation, your business can not only maintain a resilient digital presence but also unlock the potential for growth and success in this dynamic market.
