Unfortunately, The names ‘Camembert’ and ‘Brie’ are not protected. Only the specific name ‘Camembert de Normandie’ is. In the case of Brie, only ‘Brie de Meaux‘ and ‘Brie de Melun’ are. So anyone, anywhere can call their cheeses Brie or Camembert in the same way that cheddar cheese is made around the world not only in Cheddar in England where it originated.
So, the likes of Mexican Camembert is not really fake in legal terms, but morally dubious. Most countries at least make an attempt to stick to the original recipe when making off-piste versions in other counties.
The Mexican goat Camembert sounds terrible and I'm a goat's cheese lover.
