U.S. DEPARTMENT OF THE TREASURY
Treasury Targets Procurement Agents Who Supply Prohibited
Components for DPRK Missile Development
June 15, 2023

WASHINGTON — Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control
(OFAC) sanctioned two Democratic People’s Republic of Korea (DPRK) nationals involved in the
procurement of equipment and materials that support the DPRK ballistic missile program. The
DPRK continues to utilize a network of representatives in foreign countries, including the People’s
Republic of China (PRC) and Iran, to illicitly import restricted components necessary to conduct
research and development of its unlawful weapons of mass destruction (WMD) and ballistic missile
programs, in violation of multiple UN Security Council resolutions.
“The DPRK’s ongoing development of its ballistic missile program – even Pyongyang’s recent failed
military satellite launch – continues to threaten regional and international security,” said Under
Secretary of the Treasury for Terrorism and Financial Intelligence Brian E. Nelson. “The United
States is committed to targeting the regime’s illicit procurement networks that feed its weapons
programs.”

DPRK PROCUREMENT REPRESENTATIVES
The DPRK relies on foreign-sourced ballistic missile-related components that it cannot produce
domestically. To obtain these components, the DPRK uses an extensive overseas network of
procurement agents, including officials who operate from DPRK diplomatic missions or trade
offices, as well as third-country nationals and foreign companies.
The Second Academy of Natural Sciences (SANS) is a national-level organization responsible for
research and development of DPRK’s advanced weapons systems, including missiles and likely
nuclear weapons. SANS is designated by the UN and U.S. for its involvement with the DPRK’s WMD
programs. SANS uses numerous subordinate organizations and international representatives to
procure foreign technology, equipment, materials, and information used in the research and
development of advanced weapons systems, including missiles and likely nuclear weapons.
Choe Chol Min is a Beijing-based SANS representative who has worked with DPRK weapons
trading officials, PRC nationals, and other associates to purchase and procure a range of items,

including items known to be materials used in the production of DPRK ballistic missiles. Choe Chol
Min has also collaborated with SANS representatives to facilitate the dispatch of over a thousand
DPRK workers to the PRC and has supported the DPRK’s primary weapons trading entity. Choe
Chol Min received procurement requests from the DPRK for items and coordinated with associates
to fulfill those orders. Furthermore, Choe Chol Min has worked with DPRK weapons trading officials
to purchase electronic equipment for Iranian customers.
Choe Chol Min is being designated pursuant to Executive Order (E.O.) 13382 for acting or
purporting to act for or on behalf of, directly or indirectly, SANS, an entity whose property and
interests in property is blocked pursuant to E.O. 13382.
Choe Chol Min’s wife, Choe Un Jong, is a Beijing-based North Korean national and is officially
assigned to the DPRK Embassy in the PRC. Choe Un Jong has previously accompanied her
husband, Choe Chol Min, on official travel related to his work with the DPRK’s primary weapons
trading entity. On at least one occasion, Choe Un Jong helped coordinate an order with one or
more SANS associates for dual-use bearings that are used in DPRK ballistic missile production.
Choe Un Jong is being designated pursuant to E.O. 13810 for being a North Korean person,
including a North Korean person that has engaged in commercial activity that generates revenue
for the Government of North Korea or the Workers’ Party of Korea.
Today’s action will further restrict the ability of SANS to procure various items, including items that
are listed in the North Korea Ballistic Missile Procurement Advisory, that the DPRK uses in the
production of its ballistic missiles.

SANCTIONS IMPLICATIONS
As a result of today’s action, all property and interests in property of the designated persons
described above that are in the United States, or in the possession or control of U.S. persons, are
blocked and must be reported to OFAC. In addition, any entities that are owned, directly or
indirectly, 50 percent or more by one or more blocked persons are also blocked unless authorized
by a general or specific license issued by OFAC, or exempt, OFAC’s regulations generally prohibit all
dealings by U.S. persons or within the United States (including transactions transiting the United
States) that involve any property or interests in property of designated or otherwise blocked
persons.
In addition, persons that engage in certain transactions with the individuals or entities designated
today may themselves be exposed to designation. Furthermore, any foreign financial institution
that knowingly facilitates a significant transaction or provides significant financial services for any

of the individuals or entities designated today could be subject to U.S. correspondent or payablethrough account sanctions.
The power and integrity of OFAC sanctions derive not only from OFAC’s ability to designate and
add persons to the Specially Designated Nationals and Blocked Persons (SDN) List but also from its
willingness to remove persons from the SDN List consistent with the law. The ultimate goal of
sanctions is not to punish but to bring about a positive change in behavior. For information
concerning the process for seeking removal from an OFAC list, including the SDN List, please refer
to OFAC’s Frequently Asked Question 897. For detailed information on the process to submit a
request for removal from an OFAC sanctions list, please click here.
