There may have been minor slave importations through the countries I mentioned but probably just used for transportation to the surrounding regions. The reality is if you look at most of Central America such as Nicaragua, Guatemala, Honduras, El Salvador, there are no large amounts of Black people. Belize is the exception so do not use it as an example demonstrating the rule. Don't mistake dark-skinned indigenous people as having Black blood in them. Mayans are very dark while Incans (in Peru) usually are a little lighter in contrast. Has to do with the level of sun exposure in the given environments and being in the flatland vs. the mountains. Argentina is mostly Italians and German immigrants and they wiped out most of the native Americans driving them into the desert and mountains. Peru and Chile are largely indigenous. Yes at some point there may have been some slaves transported there temporarily but judging by the attitudes, prejudice and racism many Peruvians have against Blacks in particular both in that country and in North America I doubt it was in very large numbers. The Peruvian attitude towards Blacks in my opinion largely stems from the perception of genetic inferiority. Many Peruvians are short and small in stature, even smaller than indigenous groups native to Mexico.
If you look at the history of slavery the countries I mentioned had the lowest slave population percentage. They imported slaves into countries where the locals were perceived to be too small or weak to perform hard labor or if there simply weren't enough of them. In the unique case of Ecuador I believe the Spaniards found it very difficult to get to due to the mountainous environment. So Ecuador was barely "controlled" per se in the ways the other countries were and therefore they also received little to no slaves. The people of Ecuador to my knowledge don't have a drop of Black blood in them so to speak. In Mexico they had plenty of indigenous people who didn't die from smallpox and other European diseases so there wasn't as much of a need compared to North America. Then again to the best of my knowledge Spaniards were not in the habit of fukking goats, sheep and cows in the ass so they did not have as many communicable diseases of that nature compared to the British.
The legacy of this can be seen in the people. In territories conquered by Simon Bolivar formerly known as Gran Colombia in the upper half of South America, there are Black people who have lineage dating back to the colonial days. In other countries such as Costa Rica the majority of Black people there are RECENT IMMIGRANTS only dating back 100 years from Jamaica and other Latin countries with a stronger presence of African slaves. Aside from Brazil those territories are the main region where Blacks were imported in South America. You had a couple of groups of former slaves that moved down to Argentina as cowboys but that is very rare.
So in summation for example just because you found a group of Black Mexicans that doesn't mean that they constitute a relevant portion of that population. Most of the Black Mexican villages in Mexico have historically been close to the U.S. border. So it is very possible they are merely descendants of escaped slaves from the Southeastern U.S.
I have talked about this with many Mexicans over the years and while they acknowledge there was a Black presence in Mexico at certain periods of time, they were largely during upheavals such as the American Civil War, their Independence from Spain and other key historical events that occurred in-between leading to the migration of people. Mexicans are very vocal about this, they differentiate themselves from Latinos in that they are NOT mixed with Black at all in general. And this is genetically true.
On the other hand, I know many Colombians and Venezuelans who are literally 1/3 Black, 1/3 Spaniard and 1/3 indigenous which is what many of us North America understand as the "Latino" or "Hispanic" blended identity. To keep the discussion simple I leave the Carribean out of my examples as they are typically melting pots.
shyt is making me really think, at first I was 
with illegal immigration and viewed it as Mexicans reclaiming what White Americans took from them
latinos are our friends Mexicans are our enemies caribean latins are mostly cool porque la mayoria de ellos son morenos keep up
