How worried should China be about slowing economic growth?

To which my answer is, quite a lot. Communist Party credibility hangs on China being able to sustain growth in and around 6%. And these growth numbers, at least from the state statistical bureau bring us down to 6% in the most recent quarter. So, what China will now be seeking to do is to change its domestic economic policy settings to encourage the private sector back into investing for the future. That's critical, because in the last 18 months they've been sitting on their cash.
