 In a 2006 intelligence report, Zokwang was described as a local unit of a North Korean company called Daesung Chongguk, officially involved in the machinery and textiles trade and allegedly coordinating opium trafficking, which was using Macau "as a base to move counterfeit dollars and to try to procure components for its weapons systems".North Korean government officials and other sources state that the company engages in legitimate business transactions, purchasing cigarettes, food, liquor, televisions, and luxury goods for shipment to Pyongyang, but police long had suspicions about Zokwang's activities.One of its officers, An Gun-ho, was identified as a senior counterintelligence officer of North Korea's Ministry of Political Security.
