The U.S. Department of the Treasury has announced a list of North Korean individuals and organizations that are suspected of having engaged in illicit activities and will be subject to new U.S. sanctions.

The list of 22 North Korean institutions includes the Namchongang Trading Corporation, which is thought to be handling the funding for North Korea’s nuclear program.

Of the two individuals that will be sanctioned, one of them is Kim Tong-myong, the chief of Tanchon Commercial Bank. Kim is thought to have managed slush funds for top North Korean officials, including leader Kim Jong-il.

This is the first time the Treasury Department has officially named North Korean groups and individuals for sanctions since the U.N. Security Council passed resolutions 1718 and 1874.

The new blacklist is based on financial transactions the U.S. has been tracking.
