I've read about this a bit now and it clearly says the Mexicans are settling down in Colombia but NOT with an army, they are not trying to take over territories although they finance their partners over there in their wars.. They basically wants to cut out the intermediaters since its very usual that Colombians,Panamanians,Ecuadorians bring the coke to them in Mexico for about 15k a kilo.

Seems to me they are doing what the Ndrangheta has done for decades now. Establishing more Brokers in Colombia.
