My friend, I told you before, last year, about 17% of China's GDP came from exports. That's way less than many other countries such as Germany, and probably including Vietnam.
And 13% of the total exports goes to the US market. The rest goes to the rest of the world.
Now, do the math and see how important US market is for China.
Probably, again, much less than it is for Vietnam.
You will say TPP.
Well, if you have TPP, China has BRI.
See which one is more comprehensive and which one has taken more strides.
