President Barack Obama has signed an executive order mandating new financial sanctions on North Korea, senior administration officials say.
The sanctions will hit eight North Korean “entities” and four individuals, targeting the trade in arms, luxury goods and narcotics.
The new sanctions come after the sinking of a South Korean warship in March, in which 46 sailors died.
North Korea has denied responsibility for the sinking.
But an international investigation blamed Pyongyang for the sinking.
The US Treasury Department said the sanctions were aimed “at freezing the assets of [weapons of mass destruction] proliferators and their supporters thereby isolating them from the US financial and commercial systems”.
