Shoes, electronics and clothing are just some of the goods that could get more expensive under the trade agreement President Donald Trump announced with Vietnam on Wednesday.

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.
