I don't know about English but I don't think they are lots of them in French. One I can think about is Josephine Baker (YouTube)'s La petite Tonkinoise (lyrics) though it's no kids' song.

It's hard to put a request "Song Indochine" into Google because Indochine is the name of a French rock group.
There are army songs (lyrics only) from the colonial period but you wouldn't want to teach them any of them I suppose. Nobody would!

When I was a kid, we used to recite...

"Connaissez-vous Nénette Rintintin
Qui habite au Tonkin?
Son bateau a chaviré,
Nénette Rintintin s'est noyée
Dans une barque en papier"

... as a counting-out rhyme
