Well... I don t get it.
If China lost 3.5% of their GDP previous activity, how could the next growth number, assuming still 7% increase on other parts of GDP, be 6.76% ?
I understand the operation you did (96.5% of 7%) but can't see the logic behind it.
GDP the next year would look like 96.5*1.07=103.255 , so 3.255%growth, if US exports disappear and all the rest keep on climbing 7%
I suspect cutting all exports to the US would create quite a mess.
