I was thinking about Andrew's answer as I drove home. When I got here I found Norman's response. It made me think a little further. So I took a look at the Times Educational Supplement's 'intelligence' on business studies. It is more or less the most widely accepted and impartial listing worldwide and when you really look through all of their reviews and so on there are usually answers. They have little on distance learning though, but then 90% or more is simply rubbish anyway. Beware also, many masters degrees are a waste of time because they go through the motions but not teach anything whatsoever. The vast majority of the private schools are no more than an office from where they send out pre-prepared 'courses' and pay people, many of whom are not qualified properly, to mark and supervise the courses. The exams are not worth a cent and the qualifications worth less.
Take a look at the simplest table of ranking for business schools in the TES. In business studies the top French rating is 65th. I know what Andrew is saying and agree but recent details of just over 40% of all French postgraduate students looking for study places outside of France and increasing, with the majority of them now looking for international qualifications, then the goalposts are moving fast. France has a bad record on all business training so far with exception of a couple of Paris universities and international business schools (mostly US) in Paris. Big companies are looking for people who can work with and/or in other countries, so business studies in other languages, which are mainly English in the Netherlands, Germany, Switzerland, Sweden, Norway... are gaining favour. If, like Andrew, it was languages or a social science like me then I would go for French. Even the French business community know there is a world outside.
There are no specific distance learning masters included, but these are university and business school rankings. There are various reviews of the masters courses but several contradict the other so do not take them as seriously. Otherwise Norman has just about said exactly what you need to know:
