What type of wine pairs best with Vietnamese food?

Sunday marked not only the start of the Chinese New Year but the Vietnamese New Year celebrations too - known as Tet. As in China there are certain foods which are traditional to the occasion such as pickled vegetables and candied fruits, none of which are particularly wine-friendly but in general I find Vietnamese food, with its milder heat and fragrant herbal flavours easier to match than Thai (although I haven’t had such extensive experience of doing so).
