Yevgeny Primakov, head of SVR (foreign intelligence service)

Yevgeny Primakov (aka “Primus”), the head of the SVR [The Foreign Intelligence Service of the Russian Federation, Russia’s external intelligence agency, succeeded the First Chief Directorate of the KGB in December 1991] under Yeltsin.

Primakov conducted behind-the-scenes negotiations to free KGB spy Kalmanovich and supervised the arms trade conducted by Mogilevich in Europe.
So we can conclude this:
the KGB spy Kalmanovich after release from prison in Israel, moved to East Europe to join criminal organization of another KGB spy Semion Mogilevich, and the both were acting under control of Primakov. And in general russian mafia aboard was serving interests of russian secret services.

Primakov as the head of SVR controlled operations of arms trafficing to criminal gangs and third-world countries, even to middle east terrorist organizations. To avoid direct contact between russian government officials and customers, they used russian mafia bosses (and SVR agents at the same time) as proxies in this shady deals.

Involved into fraud operations with Iraqi oil withing ‘oil-for-food’ campaign:

This oil company, run by Primakov’s sister, bought oil from Iraq under “oil for food” at a heavy discount, and then sold it at full market value to primarily US companies, splitting the difference evenly with Primakov and the Iraqis. This US-sponsored deal resulted in profits of hundreds of million of dollars for both the Russians and Iraqis, outside the control of “oil for food”.
