It's true that there will be a bit of a slowdown but you have to remember that 7% growth P/A for a country the size of China is truely amazing compared to anything. And the at the end of that five years 7% will be like 10% today. As the economy grows a lower % increase is needed to sustain current demand and at the moment that demand is still huge.
Still looking good to me.
