The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) added two North Korean officials to its list blacklist on Tuesday for their involvement with the DPRK’s ballistic missile programs.

Kim Jong Sik, the Deputy Director of the Workers’ Party of Korea Military Industry Department and Ri Pyong Chol, First Vice Department Director of the Workers’ Party of Korea Central Committee were both added to OFAC’s sanctions list.

“Treasury is targeting leaders of North Korea’s ballistic missile programs, as part of our maximum pressure campaign to isolate the DPRK and achieve a fully denuclearized Korean Peninsula,” Treasury Secretary Steven Mnuchin said in
