Wal-Mart has its presence in over 27 countries and has retail outlets in 11000 units. It has e-commerce websites in over ten countries. They have partnered with a number of local retail chains in each country and slowly spreading their business across the globe. This partnership strategy helps Wal-Mart sustain the socio-economical challenges in those countries. They have spread into the North American and the Latin countries. Apart from this their presence is seen in the African, South Asian, European markets. There also have expansion plans to spread in more countries. However the international environment has always not been favorable to Wal-Mart expansions. During the initial stages of expansion in early 1990s, Wal-Mart tried to penetrate into the Mexico and Canadian markets. They faced challenges in meeting the demand of a local market and in this they strategized to understand market structure and the needs of the people in Canada and Mexico which were similar to the needs to the people in the US. They also made simultaneous attempt to move to Brazi. This was their first footing in the Latin American markets. The uniqueness of Wal-Mart is that they were able to decipher specific success economic models for each geographical location. They did face challenges in trying to sustain in many markets. The socio economic and political models in each country vary.
