What were the dificulties that walmart encountered in its incursion
into Mexico in the early 90's?

"According to various press reports, Walmart failed to observe
Mexico's labeling requirements related to providing Spanish language
labels for thousands of products exported to Mexico for sale in
Walmart's Mexican stores. Although Walmart advised Mexican trade
officials that its failure to provide the required Spanish language
labels was an unfortunate misunderstanding, Mexican trade officials
temporarily shut down Walmart's Mexico City store and did not allow it
to re-open until Walmart officials had corrected the labeling
deficiency."
