A North Korean national received a four-week jail sentence in a Singaporean court Tuesday, after pleading guilty to four counts of conspiracy to supply luxury goods to a Pyongyang department store in violation of UN and Singaporean sanctions.

Li Hyon, the son of unindicted co-conspirator Li Ik, completed his studies in Singapore in 2014 and served as his DPRK-based father’s business liaison in the Southeast Asian city state until 2017, when the scheme was revealed to media and Singaporean investigators.
