SINGAPORE—A tariff agreement with Vietnam emphasizes one of the White House’s top priorities in this frantic round of dealmaking over global trade: slamming shut any backdoor routes for Chinese goods to enter the U.S.
A key provision of the Vietnam deal announced by President Trump Wednesday is that goods “transshipped” to the U.S. through Vietnam would be subject to a punitive 40% tariff, twice the 20% rate Trump said he is applying to regular imports from Vietnam.
