The 'real' Github clone in China is called gitcafe, available at: https://gitcafe.com
I have been involved with the community for many years... and therefore I do not completely agree with your statement: "there are not enough open source projects and contributors in China". We have them, and they generally contribute directly to the projects involved (as it should be as you do not want to create islands/insular projects). Local (and localized) initiatives are great and I hope this is what you meant.
I mean that the number of people who contribute to, the quality and activity of local projects is not very good, compared to the projects on Github. And the contribution from China to international projects is also not very big.
The open sources community in China is still small and lack solid industry support. We should build a bigger community and let more people have the ability and will to contribute.
