It wasn't my intent to doubt the potential of local developers. China has a lot to offer and I actually strongly believe, as the end of my post implies, that we'll see a rising participation of Chinese developers in the OSS community. Heck, most of my teammates are Chinese and they kick asses.
That being said, on the ground it still feel very fragmented and insular. Some of the fundamentals of a healthy and self sustaining local culture are still missing.
