A study of the elements of a domestic market and those of an international market may reveal many crucial differences, especially political, legal and cultural differences. For example, the "rules of the game” of business in the international market are diverse, changeable and often unclear. The international firm may have to content with different legal and ethical standards in different host countries. In this paper the parameters of the political, legal, and the cultural environment of international business will be considered, The paper also relates how political, legal, and cultural incidents or situations may become roadblocks to the smooth operation of business ventures in foreign countries. Misunderstandings and breakdown in communication often arise from differences in perception by executives who are not from the same cultural, legal and political background. International investors need to know what elements in a foreign culture have the greatest influence over consumption patterns in general and particularly the consumption behaviour to their specific product. By reflecting on the language, religion, demography, climate, values and beliefs, education, labour, roles of women, family, ethnic groups and other similar elements, the international business person will be able to, not only participate in the international economy with a better perception of the situation, but also be able to cater for the needs of the international buyers.
