The variety of differences encountered when interacting with people from other cultures can be daunting for foreign nationals operating in another country. Consequently, many companies send their managers on some form of cultural orientation training, before beginning their duties in a foreign country. This paper seeks to examine forms of cross-cultural training, and assess the relative effectiveness of each. Potential participants were identified using a stratified random sample of companies that do business in Mexico. The data showed that meetings with experienced international staff were the most common type of training. The second was lecture training. Behaviour modification methods and field experiences were the methods that were the greatest help to US managers in understanding Mexican culture. Analysis of the data would seem to support the idea that there must be factors other than training that influence a US managers understanding of Mexican culture. A possible explanation is the level of psychic distance between the cultures of those involved in the interaction. Companies should use meetings with experienced expatriates as a central part of their training programme.
