I doubt China has 7m persons writing code in the same way that I doubt there are 1.6m people pumping code in the US. That being said, they are pretty close to being in a "closed universe" of their own. Some companies are trying to open up (deepseek, tencent, alibaba, etc...) but it is a relatively a new thing. If you go low in the stack (Operating Systems, compilers, developer tools, etc...) it's all American but in mainland China they make everything custom and different (more aligned with their culture and how they do business). If you want to get in touch with them, find projects in GitHub where the Chinese hangs out (ie: they like P2P/sharing/decentralized stuff) and send an email. My experience is that they are eager to try your stuff or get in touch but there can be a significant language barrier.
