What's the problem with China's growth? China uses to be a friend when they can only manufacture T-shirts and socks, now a threat when they can even do chips and aircraft? The foreign policy of the US is a failure, wars in mid east and anti-terrorsim has costed too much, and that gave China an opportunity to grow. You cannot blame China for this. The business practice need to be changed for sure, but let's hope there is no war.
