File Transfer That Actually Works in China
WeTransfer is blocked. Google Drive is blocked. Dropbox is blocked. Sinosend routes through Hong Kong - and soon stores data directly inside China.
The problem with sending files to China
WeTransfer is blocked
Your download link hits the Great Firewall and silently fails. Your contact never gets it. You never know.
VPNs aren't the answer
Unreliable, increasingly illegal for business use in China, and you can't ask your vendor to install one just to receive a spec sheet.
WeChat and email don't cut it
File size limits, no tracking, no branding, and files that disappear. Not a professional B2B document delivery tool.
What's blocked right now
I built Sinosend because I kept running into this problem myself working out of Hong Kong. You send a file, you hear nothing back, and you assume your contact is ignoring you. They're not - your link just silently failed at the border. The Great Firewall is not a bug or a temporary restriction. It is permanent infrastructure that blocks WeTransfer, Google Drive, Dropbox, Box, Gmail, and Slack - completely, not intermittently. OneDrive and SharePoint sometimes load, but so slowly they're effectively unusable for large files. The frustrating part is there's no error message on either end. The sender thinks the job is done. The recipient in Shenzhen or Shanghai never even saw the link. For anyone doing real business with China - sending tech packs, contracts, design files, or proposals - this is not an edge case. It happens on almost every transfer.
Where your files are stored is the whole problem
When you use a Western file transfer tool, your file sits on a server in the US or Europe. Every time your contact in China clicks the download link, that request has to cross the Great Firewall in both directions. Sometimes it makes it. Often it doesn't. And you'll never know which. The fix is straightforward: put the file closer to the person downloading it. Sinosend currently routes all Asia-Pacific transfers through Hong Kong, which sits outside mainland China but has direct, fast, unrestricted connectivity into it. That's why it works when WeTransfer doesn't. We're also building something I haven't seen any other self-serve file transfer tool offer - a data centre in Hangzhou, inside mainland China, on Alibaba Cloud infrastructure. When that launches, files sent to Chinese recipients will be stored on a server inside China. No firewall crossing at all. And no ICP licence required on our end to make it work. For now, senders in Europe use our Frankfurt node, North America uses Silicon Valley, the Middle East uses Dubai, and everyone sending to China uses Hong Kong. The file always starts as close to the recipient as possible.
