In February, Macao‘s banking regulators froze $25 million worth of North Korean accounts in the Banco Delta Asia, a bank the U.S. Treasury Department had accused in September of helping the North Korean government launder money and distribute counterfeit U.S. currency.
A North Korean company, Jokwang Trading Co., long believed to be a front for illicit activities, closed its headquarters on the fifth floor of an office building near the bank. Most of its personnel have relocated to Zhuhai, just across the border in China proper, business sources here say.
