While Vietnam’s elite speaks French, its civil servants and business community adopted English in 1994, the year of the country’s incorporation in ASEAN1. Once the main language, French has now become a second foreign language.

For a long time French monopolized the « market » for the second foreign languages on offer to young Thais (English being the first language and compulsory); today, French is having to compete with Chinese, Japanese and German. Hence the change in balance: with around 45,000 individuals learning French for a population of 12 millions pupils and students, French is now less present in Thailand than it was in the seventies.

While three million Chinese viewers are said to regularly watch the « Bienvenue en France » programmes broadcast by the central television, French as a language is well and truly absent in China, where it is studied by only 12,000 people, including 500 secondary school pupils.
