Latin America is a HUGE market for concerts especially for big artists because they can book stadiums down there yet Gaga has 0 dates booked in the region for her current tour
Gaga's last tour (born This Way ball) was received poorly there when Madonna was touring Latin America in 2012 and she outsold Gaga 3 tickets to 1.
Did Gaga stop being a force in that region?
Why didn't she book at least 1 show in Mexico or Brazil?
Well first off, it's impossible for a country to tour. It's fixed onto the earth. Secondly, it's also impossible for a person to be a country. Gaga can't be a "touring Latin America".
