According to estimates, about 40 % of all international business deals fail because non-native speakers are not able to make themselves understood or do not understand their foreign business partners on an intercultural level. Anyone who learns a foreign language, goes to a foreign country or deals regularly with foreign business partners does well to learn about non-verbal communication so as to avoid faux pas or feeling excluded.
Learners of Business English must know how to handle the different conventions and customs of countries in the English-speaking world in order to avoid embarrassing situations or making mistakes that could damage their business dealings.
My Business English training always looks at the culture of English-speaking nations as well as the language. I also incorporate foreign countries such as Thailand, Japan, China and India where English is the language of business but not necessary the mother-tongue of business partners in these countries.
