 Zokwang Trading was founded in 1974 in Macau, then under Portuguese administration, soon after Portugal recognised North Korea, following the Carnation Revolution, in which a left-wing government came to power.It functioned as North Korea's "de facto" consulate in Macau, issuing documents and visas.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".
