US Sanctions Chinese for Enabling Crypto Money Laundering
In a press release published earlier this week, the Office of Foreign Assets Control (OFAC) within the Department of the Treasury in the United States, stated that it had sanctioned two Chinese nationals and a Hong Kong British national for allegedly having aided the North Korean government in crypto money laundering activities.

The Americans claim that the funds are the proceeds of cyber crime with the laundered money in turn being used to support the Democratic People’s Republic of Korea (DPRK) regime, including its ballistic missile and weapons programs.
Illicit OTC crypto trades
The three OFAC-sanctioned individuals are Wu Huihui (Wu), Cheng Hung Man (Cheng) and Sim Hyon Sop (Sim). Wu is an over the counter (OTC) cryptocurrency trader based within China. OFAC claims that he has facilitated the conversion of millions of dollars worth of stolen digital assets into fiat currency at the behest of a North Korean cyber-crime syndicate.
In 2009 OFAC sanctioned a small North Korean bank, Korea Kwangson Banking Corp. (KKBC). At the time, the agency claimed that KKBC had extended financial services to previously designated North Korean banks including Tanchon Commercial Bank and Korea Hyoksin Trading Corporation. Fourteen years on, OFAC has now identified Sim as a facilitator of KKBC money laundering schemes. OFAC claims that Sim represented the sanctioned bank, and in the process, he was the recipient of millions of dollars worth of cryptocurrency.
Overseas earnings
The agency claims that the source of this money was the earnings of North Korean IT workers who had worked overseas, including within the United States. The North Korean regime has pursued a strategy of sending workers into employment overseas in an effort to raise capital in harder currency.
Like Wu, Cheng was also identified as an OTC cryptocurrency trader. It’s understood that Cheng collaborated with Wu, and employed a series of shell companies in order to convert cryptocurrency into fiat money.
Blockchain data analysis firm Chainalysis has researched the topic based upon the OFAC and Department of Justice data and information. That analysis has revealed that the North Korean hackers and cyber-crime facilitators make use of cryptocurrency mixers such as Tornado Cash and Sinbad. While other illicit entities utilize these crypto mixers which attempt to obfuscate the origin of digital assets, Chainalysis’ research suggests that the North Korea-affiliated actors use mixers to a far greater extent than others.
Reward offered
It’s understood that the US authorities indicted a fourth person who remains unknown beyond his/her online moniker, “live:jammychen0150.” Properties in the United States connected with the three known individuals have been frozen. The State Department has also outlined its willingness to provide a reward of up to $5 million for any information that leads to the arrest or conviction of Sim. Furthermore, rewards of $500,000 each are being offered relative to the apprehension of two of Sim’s associates, Han Linlin and Qin Gouming.
In a statement, Department of Justice Criminal Division Assistant Attorney General Kenneth Polite Jr. said that “the North Korean operatives have innovated their approach to evading sanctions by exploiting the technological features of virtual assets to facilitate payments and profits, and targeting virtual currency companies for theft.”
