Walmex says working with Mexican authorities
Mexico's attorney general's office said earlier on Thursday it has begun a probe to establish whether a criminal investigation into the allegations is warranted.
Walmex, as the company is known locally, said it was setting up a process to guarantee that it meets all requests from Mexican authorities.
"This process is part of a wider program to strengthen the confidence of Mexico's society at large about the nature and scope of its operations," the company said in a statement.
