We've been having these every month for the past year and a half. We're also having a JS meetup (node.js, marionette.js...) this Saturday: http://shanghaios.org
I think what people seem to be saying is that China is one of the only countries so blatantly using it for economic espionage against private corporations. This is fundamentally different than what other countries are rumored to be doing.
Exactly. Moreover, every nation is also denying it. Some reports make fun of China because they deny something that seem obvious, but this is no China specialty.
Just another aspect of anti China sentiment, that's all.
