France was just being a good ally. A number of formerly Dutch holdings had been captured by Britain, and recaptured by France, who turned these islands back to the Dutch.
France had been worried about the Anglo-Dutch alliance since at least the end of the 17th century. This was the first time that the Dutch allied with France against England, rather than vice-versa. France hoped to have the Dutch as allies in any potential future conflict with England.
