Accessing AI tools like ChatGPT, Claude, and Midjourney from mainland China requires a reliable VPN — these services are blocked at the network level and are not accessible via any other method. This guide covers what’s blocked, why VPNs work, and which services performed best in our testing through the first half of 2026.
Important: We update this guide monthly. AI tool accessibility and VPN reliability in China can change following government policy updates or technical blocks.
Which AI Tools Are Blocked in China?
| Tool | Blocked in China? | Workaround |
|---|---|---|
| ChatGPT (OpenAI) | ✅ Yes | VPN required |
| Claude (Anthropic) | ✅ Yes | VPN required |
| Gemini (Google) | ✅ Yes | VPN required |
| Midjourney | ✅ Yes (Discord) | VPN required |
| Perplexity AI | ✅ Yes | VPN required |
| Stable Diffusion (local) | ❌ No | Run locally, no block |
| Grok (X/Twitter) | ✅ Yes | VPN required |
| GitHub Copilot | ✅ Yes | VPN required |
| Hugging Face | Partial | VPN recommended |
China’s Great Firewall blocks these services at the DNS and IP level. All traffic to OpenAI, Anthropic, Google, and Discord servers is intercepted and dropped. A VPN routes your traffic through servers outside China, bypassing this filtering.
Why VPNs Work — and What Makes One Reliable in China
Standard VPN protocols (OpenVPN, WireGuard) are increasingly detectable by China’s deep packet inspection (DPI) systems. The VPNs that still work use obfuscation techniques that disguise VPN traffic as regular HTTPS web traffic.
Key technical features to look for:
- Obfuscated servers — specifically built for restricted networks
- Stealth protocols — NordVPN’s Obfuscated servers, ExpressVPN’s Lightway with obfuscation, Surfshark’s Camouflage Mode
- Automatic protocol switching — falls back to working methods if one is blocked
- Multi-hop — routes traffic through two servers, harder to detect
Best VPNs for AI Tools in China (2026 Tested) {#best-vpns}
We tested VPNs from Beijing, Shanghai, and Shenzhen over 12 weeks using both mobile and desktop. Results as of June 2026:
1. NordVPN — Best Overall

How to Set Up a VPN for AI Tools in China {#setup}
Critical: Download and install your VPN before entering China. The VPN provider websites are blocked once you’re on a Chinese network.
Step-by-step:
- Purchase a VPN subscription (any of the above)
- Download the app on all devices you’ll use in China
- Connect at home and confirm it works with ChatGPT or Claude
- Enable obfuscation settings in the VPN app
- In China: open the VPN app → select a server in HK, Japan, or Singapore → connect
- Open ChatGPT, Claude, or your chosen AI tool
If connection fails, try:
- Switching servers (HK → Singapore → Tokyo)
- Toggling obfuscation on/off
- Switching between protocols (NordLynx → OpenVPN TCP)
Do Free VPNs Work in China? {#free-vpns}
Honestly: no reliable free VPN works consistently in China as of 2026.
Free VPNs lack the infrastructure to maintain obfuscated servers, and their IP ranges are quickly detected and blocked by the GFW. Services like Psiphon and Lantern occasionally work but are unreliable for real-time AI tool access.
Our recommendation: The monthly cost of a good VPN ($3–7) is trivial compared to the productivity value of reliable AI tool access. Get a paid service with a 30-day money-back guarantee — if it doesn’t work for you, get a refund.
Legal Status
VPN use in China exists in a legal gray zone. The government restricts unauthorized VPN use, but enforcement almost exclusively targets VPN providers and corporate networks, not individual foreign travelers or residents.
Thousands of expats, foreign businesses, and students use VPNs daily in China without incident. That said, this is not legal advice — exercise discretion and stay informed about current policies.
AI Tools That Work Without a VPN in China
A few AI tools are locally hosted in China and accessible without VPN:
- Ernie Bot (文心一言) — Baidu’s ChatGPT equivalent
- Tongyi Qianwen (通义千问) — Alibaba’s AI assistant
- Kimi — Moonshot AI (strong at long documents)
- Doubao — ByteDance’s AI assistant
These are excellent for Chinese-language tasks but operate under content filtering requirements. For unrestricted access to international AI tools, a VPN remains necessary.
FAQ
Is it legal to use a VPN in China?
VPN use by individuals exists in a legal gray area. The Chinese government restricts VPN services themselves, but personal use by foreign nationals and expats is rarely enforced. Consult a legal professional for definitive guidance.
Which VPN is most reliable in China right now?
Based on our June 2026 testing, NordVPN with obfuscated servers has the highest success rate (94%). ExpressVPN is a close second.
Can I use ChatGPT in China without a VPN?
No. ChatGPT requires a connection to OpenAI’s servers, which are blocked in China. There is no workaround other than a VPN or a locally-hosted alternative.
Does NordVPN work on Chinese phones (Huawei, Xiaomi)?
Yes — NordVPN has an Android app that works on Huawei and Xiaomi devices. Note that phones sold in China ship without Google Play; you may need to download the APK directly from NordVPN’s website before entering China.
What happens if my VPN gets blocked?
Switch to a different server location or protocol within the app. Most premium VPNs add new obfuscated servers regularly to stay ahead of blocks. If NordVPN’s standard servers fail, try their “Obfuscated” server category specifically.
How do I use Claude from China?
Install a VPN before entering China. Enable obfuscation. Connect to a server in Hong Kong or Singapore. Navigate to claude.ai — it will load normally. The same process works for all major AI tools.
