Macau is one dark world sitting next to Hong Kong. It may have the appearance of a modern city but its people lack the characters of a modern civic society. Ever since the Cultural Revolution in 1966 when the Communist Chinese Red Guards overran the territory (12.3 incident) it has been politically tightly controlled by Beijing.
Pao-hwa Lin, an expert on the Chinese Communist regime, (and himself a PhD graduate in Chinese Communist Party history from the Eastern China Normal University just preceding the Communist years), wrote that "North Korea used Macau as a staging post to traffic drugs, launder money, kidnap, use counterfeit US currency, and even planning terrorist sabotages...". All of that is impossible because Macau has effectively been a "semi-liberated zone" from 1966 up until its formal transfer of sovereignty in 1999. North Korea has "a trading company, several enterprises, and a restaurant" in Macau.
For more details about North Korea's activities through Macau and how China has discreetly allowed this to happen in a city it controls, have a look at this article in Chinese:

Thanks for the link. I will look it up. What you said tends to match What I heard about N. Korea's Macao operation in S. Korea. The difference, I gather, would be details on the extent of Chinese complicity. I suspect that China also has a lot to answer for.
