Official reason

In coordination with the Republic of Korea and Japan, the United States sanctioned two individuals and one entity—Jon Jin Yong, Sergey Mikhaylovich Kozlov, and Intellekt LLC—involved in generating revenue for the Democratic People’s Republic of Korea’s (DPRK) unlawful development of weapons of mass destruction (WMD) and ballistic missiles. Russia-based Jon Jin Yong worked with Sergey Mikhaylovich Kozlov (Kozlov) to coordinate the use of DPRK construction workers in Russia and served as a director of one of Kozlov’s companies. Kozlov has assisted Jon Jin Yong in the procurement of items commonly used in the ship-building industry. Jon Jin Yong led a team of DPRK information technology (IT) workers in Russia and worked with Russian nationals to obtain identification documents to validate the DPRK IT team’s accounts on freelance IT work platforms. Some of the identity documents were from family members or Russian employees of Kozlov. OFAC is designating Jon Jin Yong pursuant to Executive Order (E.O.) 13687 (“Imposing Additional Sanctions With Respect to North Korea”) for being an official of the Workers’ Party of Korea, which was sanctioned on March 15, 2016, pursuant to E.O. 13722 (“Blocking Property of the Government of North Korea and the Workers’ Party of Korea, and Prohibiting Certain Transactions With Respect to North Korea”). OFAC is designating Kozlov pursuant to E.O. 13687 for materially assisting, sponsoring, or providing financial, material, or technological support for, or goods or services to or in support of, Jon Jin Yong.
