Ok, so whatever think anyone about the FUTURE of China,US or SK at the moment SK is dependent on the US technology and markets to prosper, like China.
It can change in the future, and of course it doesn't means that any party won't willing to take even extreme level of economycal hardship to reach a strategical goal.
But, the current SK/US relations making any trialt o get rid fo the US a very hard and expensive adventure, and the US has many means to kill this idea.
And sadly many of the comments about future prospect of Chinese semi industry, trade flow and deficit, efficeincy and so on require way more talk than the patience fo the moderators to delete the best part of this topics.
Why do you fixate on a FALSE claim? Here is the latest trading figures of SK (2017 Dec. 1) from world bank which is more reliable than yourself.
SK export 156 BUSD to China (mainland + HK) vs. 67 BUSD to US. That is much more than double.
SK import 87 BUSD from China vs. 43 BUSD from US. Still double.
Now, based on that hard facts, how could you say SK is more dependent on US for market?
