The People’s Daily of China says North Korea's top-secret Bureau 39 is the key political and economic organization of the dynasty in the North.

The official newspaper of the Communist Party of China made the statement in its online edition Wednesday, saying that the Bureau 39 building of the North’s Workers' Party of Korea ranks fourth among the world’s top ten most restricted areas.

The report added that the bureau has set up ten to 20 accounts in China and Switzerland and has been engaged in illegal activities, including counterfeiting and money laundering.

According to the report, it has been confirmed that the bureau has been involved in drug smuggling and illegal dealings of weapons.

The report, however, was taken off the Internet after it was covered by KBS.
