Explain how to choose what language to use in doing business across borders and issues with using an interpreter

What will be an ideal response?

A first step in doing business across borders is to determine what language to use. English is regarded as the language of international business, because it is the most frequently used.32 The language that businesspeople are most likely to know other than their native language is English. Even in circumstances where managers from one country do know the language of their counterparts' country, they may prefer to speak English. French and German managers, for example, may conduct business discussions in English, because it does not give either side an advantage.
Alternatives to using English are to use the language of one of the parties, use another language that both parties are willing to use, or rely on interpreters. When the supplier and customer managers do not have a common language that they are comfortable using for business discussions, one or both parties need to employ interpreters. Use of interpreters, however, can lengthen the time needed for the business discussions, change the "atmosphere" of the discussions, increase the costs of the discussions, or increase the chances for misunderstandings. Nevertheless, doing business through interpreters is sometimes the only viable.
