Tan Wee Beng, director of Singapore-based Wee Tiong (S) Pte Ltd, is wanted for allegedly conspiring to violate U.S. sanctions by conducting millions of dollars in commodities transactions with North Korean entities from 2011 onwards. He allegedly laundered money through U.S. and Singaporean financial systems, concealing payment origins and structuring transactions to evade regulatory scrutiny, including orchestrating bulk cash hand-deliveries by North Korean operatives. A federal arrest warrant was issued on August 29, 2018, and he remains at large; locating him is critical to disrupting illicit North Korean procurement networks and enforcing international sanctions.
