This sounds like a conspiracy theory, but it is true: Chinese gangsters with ties to the Chinese government are in league with Mexican gangsters to smuggle drugs and people into the United States, and in at least some cases enslave those smuggled people on farms operating in the United States. Relatedly, Chinese gangsters with ties to the Chinese government are known to be laundering drug money through Canadian banks including TD (i.e. Toronto Dominion) bank.
None of this should be an excuse for racism of course. The gargantuan and inasatiable U.S. demand for drugs is the root driver of these problems, criminalization of said drugs creates the profit incentive, and organized crime exists to exploit opportunities like this while minimizing risks (to itself). Organized crime tends to be ethnicity based because recent immigrant groups have social ties to each other and to people and organizations in their countries of origin. And particularly in the case of human trafficking, it is the immigrants themselves who are typically exploited by criminals belonging to their own ethnic group. The risk of violence to those of us not directly involved would seem to be low, other than people who get caught up in the illegal drug marketplace in one way or another.
Nonetheless, all this needs to be smashed. And it can be smashed by traditional law enforcement, inside our traditional borders. Human trafficking and borderline or outright slavery in particular just have to be smashed without mercy. The Oklahoma story above is particularly disturbing where it sounds like law enforcement knew for quite a while that armed guards were confining and forcing people to work against their will, within the boundaries of the United States.
