"La Chine et le Vietnam sont des pays asiatiques."

Translation: China and Vietnam are Asian countries.

[Agonisti]

China is feminine and Vietnam is masculine... wat?

[CJ.Dennis]

"livre" is masculine and "pomme" is feminine, what?

Surely by now you know that French is a gendered language, and the genders are mostly randomly assigned.

[TheHandShand]

Not sure why this is in this thread.

But anyway, there IS a feminine version of the noun livre which means 'a pound'. In terms of weight as well as the currency.

[casperdewith]

To determine with quite some certainty whether a country is masculine or feminine, check: if the last letter is an ‘e’, it's probably feminine. Except « le Mexique » and a few others.

[Kate_Joy]

The male voice seems to add another syllable, Viet a nam, phonetically. Is this usual?

[Frigooss]

No, it isn't. In French, you say 'Vietnam' and not something like 'Vietenam'

[GraemeSarg]

Isn't the official French name still Viêt Nam ? It can't be all that long since Vietnam stopped being classified as slang!

I any case Viêt Nam should be accepted.

The French language wikipedia agrees with you: https://fr.wikipedia.org/wiki/Vi%C3%AAt_Nam

Larousse as well:

They should change the preferred answer here.
