China's growth rates have stayed put for nearly two decades. Any slowdown can only happen if there is a drastic worldwide decline in the demand for "Made in China" goods, or if there is political turmoil in China. As there isn't much sign of either of these happening, don't hold your breath till any of these happen.
We all like things to be different, but unfortunately, the store shelves seem to be filling with more and more Chinese-made stuff.
End even "if there is a drastic worldwide decline in the demand", it will be rather for the MORE expensive goods made OUTSIDE of China.
