Strictly speaking with regard to just the 10% tariff on DR goods coming to the US, the impact will not be that great as the amount of goods sent is reasonably small. Certain sectors will feel it more than others, but for the moment the tariff is more of getting attention to the perceived disparate trade treatment.
It is only when/if the DR decides to retaliate, as opposed to sit down a and discuss the reason(s) the 10% tariff on them took effect, will you begin to see real economic pain.
Notwithstanding your comment above regarding China, Canada, E.U. etc.,......when the US sneezes the world tends to catch a cold.
