When it becomes more expensive for producers in China to sell their goods in the US due to tariffs, bi-lateral exchange rate changes, increasing wage costs in China, etc., production does not necessarily move to the US:
Antidumping in Action, by Bill C: Today's Washington Post provides another example of our dysfunctional "Antidumping" rules in action. This case is about antidumping tariffs imposed on furniture imports from China:But do tariffs work? In the case of bedroom furniture, they’ve clearly helped slow China’s export machine. In 2004, before tariffs went into force, China exported $1.2 billion worth of beds and such to the United States.
