@Hollander Giancana established a drug route which went though Mexico but it wasnt supplied with the Mexican product. You see according to some reports, the connection was established with the help of several underworld Chinese syndicates from Macao and Hong Kong areas who operated independently from the Triads. The plan was for smugglers from the Philippines to ship raw opium to a small island on the Pacific Ocean known as Guam, which in fact it’s an island on U.S. territory in Micronesia, in the Western Pacific. The transportation process was carried out mainly by individuals who were paid by the Asian crime syndicates, until they brought it in Mexico, where it was usually welcomed by local gangs who were on Giancana’s payroll. His “voice” in the Mexico area was his main attorney know as Jorge Castillo who in turn also worked as Giancana’s front man and contact with local Mexican authorities and criminal gangs. This “landing” point was obviously chosen mainly because of the constant raids on U.S. soil and because of that, now the main smuggling route extended along the Arizona-Mexico border and was mainly controlled by members of Cosa Nostra in alliance with some of the Mexican criminal factions such as the Savela brothers and one Chinese born criminal Hector Mar Wong who in turn was the main dope smuggling contact between Mexico and the Asian criminal factions
