I'm not sure there isn't such a thing in many places, though maybe not quite as broadly based as the 'Italian Mafia' in the US. Bear in mind that in Italy, organised crime is run along regional lines (Calabrian, Apulian, Sardinian and Sicilian mobsters don't really talk to each other). It was only in the US that they were all alike treated as 'Italians' and thus could become an 'Italian mafia'. Right now, the situation in Europe could serve to create something similar. Criminal groups from several West African countries are involved in snakeheading, drug running, fencing, and the usual community-based extortion and violence right now. Lots of Europeans, both xenophobes and genuine law enforcement experts, do nowadays speak of 'African organised crime', though as yet it still appears to be Nigerian, Cameroonian, Ghanaian or Senegalese organised crime. But I could see a sense of joint African solidarity emerging from this constellation.
Of course, that would be very bad news for European policing, because especially the Nigerian groups have a repuitation for violence that would make the Albanian mafia flinch.
