An initial trade deal with Vietnam offers a glimpse of how President Trump is pushing countries to cut back on trade with China.

The United States will place a lower-than-promised 20% tariff on many Vietnamese exports, Donald Trump said on Wednesday, cooling tensions with its tenth-biggest trading partner days before the U.S. president could raise levies on most imports.

“Vietnam will pay the United States a 20% Tariff on any and all goods sent into our Territory, and a 40% Tariff on any Transshipping,” Trump said on his social network. “In return, Vietnam will do something that they have never done before, give the United States of America TOTAL ACCESS to their Markets for Trade.”
