Walmart operates in Mexico as Walmex, in the United Kingdom as Asda, in Japan as Seiyu, and in India as Best Price. It has wholly-owned operations in Argentina, Brazil, Canada, and Puerto Rico. Wal-Mart's investments outside North America have had mixed results: its operations in the United Kingdom, South America and China are highly successful, while it was forced to pull out of Germany and South Korea when ventures there were unsuccessful.

Walmart has been criticized by some community groups, women's rights groups, grassroots organizations, and labor unions, specifically for its extensive foreign product sourcing, low wages, low rates of employee health insurance enrollment, resistance to union representation, sexism, and management efforts to pressure employees to vote for specific parties during national elections. Conversely, others point out that Wal-Mart's rapid growth and logistical efficiency has enabled it to bring lower prices to consumers and more jobs to the communities in which it operates. Cerrar
