The president said he had agreed to initial trade terms with Vietnam, the second country to strike a limited deal after Mr. Trump threatened steep tariffs.

President Donald Trump announced a trade deal with Vietnam Wednesday that would allow U.S. goods to enter the country duty-free.

“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.”
