Prostitution is legal in the Netherlands as long as it concerns voluntary sex. It appears that mafia-like organizations, for example, do not hold the Red Light District in their grip anymore. Organized crime in the heart of Amsterdam's city center is mainly committed by criminals of Dutch origin. In trafficking in women, criminals from Central and Eastern Europe are involved 'at operational level'. Meanwhile, Chinese are increasingly buying real estate. In the massage parlors, where illegal sex is offered, the Chinese mafia may have a hand.
