"A lot of companies are moving to Vietnam, but Vietnam takes advantage of us even worse than China. So there's a very interesting situation going on there," Trump said.

When Bartiromo asked Trump whether he planned to impose tariffs on Vietnam, Trump didn't directly answer the question, saying, "We're in discussions with Vietnam." He went on to describe Vietnam as "the single worst abuser of everybody" and vowed to increase tariffs on China again if a trade deal isn't reached.
