The Trump administration is placing sanctions on entities it says have violated trade restrictions with North Korea.
The Treasury Department announced designations against one individual and three entities from China, Singapore and Russia on Wednesday.
The department said some of the companies worked together to falsify shipping documents so they could send "alcohol, tobacco, and cigarette-related products" to North Korea.
These designations are part of a larger push to maintain pressure on the Kim regime to denuclearize.
