Ted in Italy there are the art 416 penale code associazione a delinquere (conspiracy) where the people that made a deal for create a organization that use violence for their needs are santionated once proved the existance of the deal; so every people even white collar men that are associated for break the law can be arrested.
The 416 bis associazione a delinquere di stampo mafioso (mafia type conspirancy) sentence the organization that fall under the OC group localy named (ndrangheta,camorra etc).

The people in the fist case risk to 3 y to 7 y and in the second case over 14 y.
But is based on the italian experiences against the mafia that started with the Rognoni-La Torre law in 1982.
So in the other state apart the RICO there are no simil law.
