Walmart is the largest retailer and employer in the world. The massive American multinational retail corporation employs approximately two million people and has a presence in 15 countries under 55 different names. Serious concerns surrounded some of Walmart’s ventures outside the United States – operations failed in South Korea and Germany. However, the vast majority of the corporation’s international projects and acquisitions have now proven highly successful.Today, Walmart has a total of 4,625 stores in the United States, a number dwarfed by the corporation’s international operations. There are 6,148 Walmart stores away from U.S. shores, with the majority concentrated in Mexico – America’s southern neighbour has a total of 2,353 Walmart stores. In Mexico, Walmart operates as Walmex. In the United Kingdom, it is run as Asda, while in Japan, Walmart falls under the Seiyu brand.
