South Korea announced new unilateral sanctions against North Korea for the first time in five years on Friday, designating more than 30 DPRK individuals and organizations in protest of its accelerated missile testing.

The new measures, which aim to stifle Pyongyang’s weapons programs, designate persons and entities already covered by existing U.S. and U.N. sanctions, according to Seoul’s foreign ministry.

“Our government strongly condemns North Korea for recently broaching the possibility of using tactical nuclear weapons against the ROK, as well as conducting back-to-back missile provocations with unprecedented frequency,” the ministry states in a press release announcing the new designations.
