It's anecdotal, but I live a fair bit of the time in Guangzhou and noticed a lot of Chinese developers I've met there have taken great interest in Go. The surge in popularity seems to have been since an impressively detailed ebook in Chinese on writing web applications in Go[1] was released a couple of years back now, and remains a very popular project on GitHub.

It is worth noting though that the most popular languages in China reflect the major languages around the rest of the world, a GitHub search for a very common Chinese character[2] shows that for the Chinese open source community.
