English is the new lingua Franca, the language of modern business. Read an interesting article in the European edition of the International Herald Tribune online. It concerns the increasing use of English as the primary teaching language in university business schools around the globe. It is particularly striking that this is happening at business schools in language-proud France and Spain, as well as in Asia.
I've seen this phenomenon in my own life. An American friend from the days when we were both doctoral students teaches business in English in Taiwan. Other Americans I once worked with later taught in English in Hong Kong, Singapore and Denmark. The other DrC and I were even offered university English teaching jobs in Guilin, China, 20 years ago while touring the country (we didn't accept).
