Does the blocking of the Government of North Korea and the Workers’ Party of Korea impact the ability of U.S. persons to do business with or conduct transactions with entities in which either party has an interest?
OFAC's answer
Yes. All property and interests in property of the Government of North Korea and the Workers’ Party of Korea are blocked. U.S. persons are generally prohibited from engaging in transactions with them without authorization from OFAC and must block property or interests in property that are in, or come within, the United States or the possession of a U.S. person.
