The United States has announced additional sanctions against North Korea.

U.S. President Barack Obama on Tuesday signed an executive order that directs related agencies to sanction individuals and entities. The North Korean agencies and individuals are allegedly linked to trafficking in arms, money laundering, the counterfeiting of goods and currency, bulk cash smuggling, narcotics trafficking and other illicit activities.

Under the new 13551 Executive Order, one individual and three organizations were slapped with sanctions. They are the North Korean army’s reconnaissance bureau and its chief, Kim Yong-chol, the Workers’ Party Bureau 39, which is believed to be charged with handling slush funds for North Korean leader Kim Jong-il; and the Green Pine Associated Corporation, which is suspected of exporting torpedoes similar to the one that caused the sinking of the “Cheonan” naval ship in March.

The three newly targeted individuals under existing Executive Order 13382 are three individuals and five entities. The five individuals are Bureau of Atomic Energy Director Ri Je-son; former head of the Yongbyon Nuclear Research Center, Ri Hong-sop; and Yun Ho-jin, who heads the Namchongang Trading Corporation.

The five newly targeted entities are the Korea Heungjin Trading Company, the Korea Taesong Trading Company, the Munitions Industry Department, the Second Academy of Natural Sciences and the Second Economic Committee.

The targeted organizations and individuals will have their assets in the U.S. frozen, will be prohibited from doing business with United States’ financial institutes and will be banned from visiting the U.S.
