There's been loads of discussion about the China's tech ecosystem on HN over many years. Of course a lot of it is politically charged, due largely to the actions of national governments and a few people's over-enthusiasm to get caught up in political battles (and it doesn't help that HN is blocked by China's firewall, along with language and cultural barriers). But there's also been plenty of discussion here between ordinary people about what's going on there.

And there are always plenty of Show HNs and other discussions from elsewhere in Asia, particularly India of course, but also Japan and Singapore.

Much of it you may not be aware of, as it's often not explicitly stated in titles or intros.
