The U.S. Department of the Treasury has announced new sanctions on two individuals within the North Korean government, both of whom are reportedly prominent figures within Kim Jong Un's ballistic weapons development program.
Ri Pyong Chol and Kim Jong Sik are now both blacklisted — which means any assets they have in the U.S. will be frozen, although as NPR's David Welna notes, "It's not clear whether either of them, in fact, has any U.S. assets." Additionally, Americans will generally be prohibited from doing business with them.
"Kim Jong Sik reportedly is a key figure in North Korea's ballistic missile development, including efforts to switch from liquid to solid fuel," the Department of the Treasury says. "Ri Pyong Chol is reported to be a key official involved in North Korea's intercontinental ballistic missile development."
Both men have appeared multiple times in photos of Kim Jong Un watching missile tests, according to North Korea Leadership Watch and reporting by Reuters. The men smile and congratulate each other.
