The State Department says it will bar US citizens from travelling to North Korea in a bid to prevent any more Americans from being taken prisoner.
The ban will come into effect 30 days after a notice is placed in the Federal Register, which is expected on Thursday.
It comes a month after American student Otto Warmbier died after being detained by the North Korean regime.
State Department spokeswoman Heather Nauert says the administration doesn't want any more Americans to put themselves in danger.
