China will change the location where they dump and the US will pick the dump up there.
For example, I would assume that Amazon will have a similar strategy with their Basics product line.
Unless sanctions come into play, but I don't think that it will. The US and China will continue to trade blows. There is also no guarantee that Trump's "plan" will bear positive results in the long term. Uneasy trade alliances are already being made with China, but who knows, maybe that is the plan.
This is better than having a conventional war, but one should hope that once this trade war simmers down, that the US and China are a bit more aligned than they were in the past. This US "plan" could still go horribly wrong.
All in all, the world order is being realigned. For better or worse, perhaps in the end there are more 'good' guys than 'bad' guys, perspective and all that.
This said, though not belonging in this thread. For the West to suppress Iran, it would need support on the other side.
