es, VPNs can be tracked in China. The Chinese government has sophisticated technology for detecting VPN usage, including Deep Packet Inspection and machine learning algorithms. In addition, VPN service providers and individual users have been traced and faced legal consequences.
VPNs in China
Legal Status of VPNs in China
The use of VPNs in China presents a gray area in the legal context. While not outright illegal, the Chinese government has placed numerous restrictions on their use. Since 2017, the Ministry of Industry and Information Technology announced a crackdown on ‘unauthorized’ VPNs. Essentially, only state-approved VPNs are allowed, which are typically used by multinational corporations for business activities. Most commercial and private VPNs are considered illegal, as they circumvent the internet censorship put in place by the government. More about these rules can be found here.
The Great Firewall of China
The Great Firewall of China, also known as the Golden Shield Project, is the country’s main instrument for controlling and limiting internet access. It uses various methods such as IP blocking, packet filtering, and DNS spoofing to block content deemed inappropriate by the Chinese government. VPNs are frequently used by individuals and businesses to bypass these restrictions. However, the firewall has evolved to detect and block many VPN protocols, making the use of VPNs in China increasingly challenging.
Chinese Cybersecurity Laws
China’s Cybersecurity Law, implemented in 2017, provides a broad framework for internet regulation in the country. The law enhances the government’s control over internet infrastructure and increases data privacy protection. However, it also places stricter regulations on internet censorship, further complicating the use of VPNs. It requires network operators to cooperate with the government in investigating ‘cybersecurity incidents,’ which can include the use of unauthorized VPNs. Individuals or companies found to be in violation of these laws can face penalties, including fines and potential imprisonment.
Tracking VPN Usage
How VPNs Can Be Tracked
Tracking VPN usage primarily involves the detection of VPN protocols. VPNs work by encrypting data and routing it through servers located in different parts of the world. This process changes the user’s IP address and hides the data being transmitted. However, most VPNs use specific protocols, such as OpenVPN or IKEv2, that have identifiable digital signatures. By analyzing network traffic, entities can identify these signatures and determine if a VPN is in use. Detailed information about VPN protocols can be found here.
Technologies Used by China to Track VPNs
The Chinese government has developed sophisticated methods to track and block VPN usage. These methods are primarily implemented through the Great Firewall. One technique, known as Deep Packet Inspection (DPI), allows the firewall to inspect the contents of data packets passing through it. DPI can recognize the digital signatures of various VPN protocols, making it a potent tool for tracking VPN usage.
Moreover, China has begun to use machine learning algorithms that can identify encrypted VPN traffic even when it is disguised to look like regular HTTPS traffic. This is possible because the timing and size of data packets in VPN traffic often exhibit distinctive patterns. By training these algorithms on large amounts of network data, the government can effectively detect and block many VPNs.
Apart from these technical methods, the government also leverages legal and administrative measures to track VPN usage. For instance, internet service providers in China are required by law to monitor their networks for ‘illegal’ VPN activity and report it to the authorities.

Real-life Instances of VPN Tracking in China
Case 1: VPN Service Providers Facing Legal Action
One of the most notable instances of VPN tracking in China involves the legal action against VPN service providers. In 2017, a man from Guangdong province was sentenced to nine months in prison for selling unauthorized VPN services. His service, which had around 8,000 customers, was traced and shut down by the authorities. This case is one of several that highlight the Chinese government’s proactive approach to tracking and shutting down unauthorized VPN providers. More about these legal actions can be found here.
Case 2: Business VPN Usage
Multinational companies operating in China often rely on authorized VPNs for secure communications. However, there have been instances where these VPN connections have been suspected of being monitored or tampered with by the authorities. One high-profile case involved a global technology company that discovered unusual network activity suggestive of a man-in-the-middle attack. The incident raised concerns about the privacy and security of business communications in China.
Case 3: Individual Users Detected and Warned
There have been several reports of individual VPN users in China receiving warnings from their internet service providers. In these instances, users received messages stating that their internet access would be temporarily suspended due to the detection of ‘illegal’ VPN usage. Such warnings serve as a reminder of the extent to which the Chinese government monitors and regulates internet use in the country. More details can be found on the Great Firewall Wikipedia page.
